For example, a rigid cage with small windows can efficiently protect its contents from the environment; in contrast, tube-shaped, flexible hosts with large openings and an easily accessible cavity are ideally suited for catalysis. Here, we report a “Janus” nature of a Pd6L4 coordination host previously reported to exist exclusively as a tube isomer (T). We show that upon encapsulating various tetrahedrally shaped guests, T can reconfigure into a cage-shaped host (C) in quantitative yield. Extracting the guest affords empty C, which is metastable and spontaneously relaxes to T, and the T⇄C interconversion can be repeated for multiple cycles. Reversible toggling between two vastly different isomers paves the way toward controlling functional properties of coordination hosts “on demand”.","lang":"eng"}],"date_updated":"2023-12-11T11:47:07Z","page":"24755-24764","_id":"14664","year":"2023","acknowledgement":"We acknowledge funding from the European Union’s Horizon 2020 Research and Innovation Program under the European Research Council (grant agreement 820008).We also thank the Deutsche Forschungsgemeinschaft (DFG) for support through priority program SPP1807(CL489/3-2) and RESOLV Cluster of Excellence EXC2033 (project number 390677874).

However, this reaction typically requires ultraviolet light, which limits applicability. In this study, we introduce disequilibration by sensitization under confinement (DESC), a supramolecular approach to induce the E-to-Z isomerization by using light of a desired color, including red. DESC relies on a combination of a macrocyclic host and a photosensitizer, which act together to selectively bind and sensitize E-azobenzenes for isomerization. The Z isomer lacks strong affinity for and is expelled from the host, which can then convert additional E-azobenzenes to the Z state. In this way, the host–photosensitizer complex converts photon energy into chemical energy in the form of out-of-equilibrium photostationary states, including ones that cannot be accessed through direct photoexcitation.","lang":"eng"}],"month":"09","type":"journal_article","oa_version":"Preprint","page":"1357-1363","_id":"13340","year":"2023","acknowledgement":"We acknowledge funding from the European Union’s Horizon 2020 Research and Innovation Program [European Research Council grants 820008 (Ra.K.) and 101045223 (A.P.) and Marie Skłodowska-Curie grants 812868 (J.G.) and 101022777 (T.-P.R.)], the Academy of Finland [Center of Excellence Programme LIBER grant 346107 (A.P.), Flagship Programme PREIN grant 320165 (A.P.), and Postdoctoral Researcher grant 340103 (T.-P.R.)], Zuckerman STEM Leadership Program Fellowship (J.R.C.), President’s PhD Scholarship (M.O.), and the EPSRC [Established Career Fellowship grant EP/R00188X/1 (M.J.F.)].","quality_controlled":"1","doi":"10.1126/science.adh9059","publication_identifier":{"eissn":["1095-9203"]},"language":[{"iso":"eng"}],"issue":"6664","title":"Disequilibrating azoarenes by visible-light sensitization under confinement","day":"22","author":[{"last_name":"Gemen","first_name":"Julius","full_name":"Gemen, Julius"},{"last_name":"Church","first_name":"Jonathan R.","full_name":"Church, Jonathan R."},{"full_name":"Ruoko, Tero-Petri","last_name":"Ruoko","first_name":"Tero-Petri"},{"last_name":"Durandin","first_name":"Nikita","full_name":"Durandin, Nikita"},{"full_name":"Białek, Michał J.","first_name":"Michał J.","last_name":"Białek"},{"last_name":"Weissenfels","first_name":"Maren","full_name":"Weissenfels, Maren"},{"first_name":"Moran","last_name":"Feller","full_name":"Feller, Moran"},{"first_name":"Miri","last_name":"Kazes","full_name":"Kazes, Miri"},{"full_name":"Borin, Veniamin A.","first_name":"Veniamin A.","last_name":"Borin"},{"full_name":"Odaybat, Magdalena","last_name":"Odaybat","first_name":"Magdalena"},{"first_name":"Rishir","last_name":"Kalepu","full_name":"Kalepu, Rishir"},{"full_name":"Diskin-Posner, Yael","first_name":"Yael","last_name":"Diskin-Posner"},{"last_name":"Oron","first_name":"Dan","full_name":"Oron, Dan"},{"first_name":"Matthew J.","last_name":"Fuchter","full_name":"Fuchter, Matthew J."},{"full_name":"Priimagi, Arri","first_name":"Arri","last_name":"Priimagi"},{"full_name":"Schapiro, Igor","last_name":"Schapiro","first_name":"Igor"},{"first_name":"Rafal","last_name":"Klajn","full_name":"Klajn, Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b"}],"article_processing_charge":"No","scopus_import":"1","article_type":"original","publication":"Science","department":[{"_id":"RaKl"}],"publisher":"American Association for the Advancement of Science","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"page":"275-287","date_updated":"2023-08-02T06:51:15Z","abstract":[{"text":"The self-assembly of nanoparticles driven by small molecules or ions may produce colloidal superlattices with features and properties reminiscent of those of metals or semiconductors.

As a case study, we focus on gold nanoparticles bearing positively charged groups that self-assemble into FCC crystals via mediation by citrate counterions. In silico ohmic experiments show how the dynamically diverse behavior of the ions in different superlattice domains allows the opening of conductive ionic gates above certain levels of applied electric fields. The observed binary conductive/nonconductive behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular level, crossing the “band gap” requires a sufficient electrostatic stimulus to break the intermolecular interactions and make ions diffuse throughout the superlattice’s cavities.","lang":"eng"}],"month":"01","oa_version":"Published Version","type":"journal_article","volume":17,"date_created":"2023-08-01T09:30:29Z","year":"2023","_id":"13346","publication_status":"published","oa":1,"date_published":"2023-01-10T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1021/acsnano.2c07558"}],"status":"public","extern":"1","intvolume":"        17","citation":{"apa":"Lionello, C., Perego, C., Gardin, A., Klajn, R., &#38; Pavan, G.

Here, we describe the concept of photocleavable anionic glue (PAG): small trianions capable of mediating interactions between (and inducing the aggregation of) cationic NPs by means of electrostatic interactions. Exposure to light converts PAGs into dianionic products incapable of maintaining the NPs in an assembled state, resulting in light-triggered disassembly of NP aggregates. To demonstrate the proof-of-concept, we work with an organic PAG incorporating the UV-cleavable o-nitrobenzyl moiety and an inorganic PAG, the photosensitive trioxalatocobaltate(III) complex, which absorbs light across the entire visible spectrum. Both PAGs were used to prepare either amorphous NP assemblies or regular superlattices with a long-range NP order. These NP aggregates disassembled rapidly upon light exposure for a specific time, which could be tuned by the incident light wavelength or the amount of PAG used. Selective excitation of the inorganic PAG in a system combining the two PAGs results in a photodecomposition product that deactivates the organic PAG, enabling nontrivial disassembly profiles under a single type of external stimulus."}],"date_updated":"2023-08-02T10:44:22Z","page":"4098-4108","date_created":"2023-08-01T09:33:08Z","volume":145,"year":"2023","_id":"13354","publication_identifier":{"issn":["0002-7863"],"eissn":["1520-5126"]},"quality_controlled":"1","doi":"10.1021/jacs.2c11973","issue":"7","language":[{"iso":"eng"}],"keyword":["Colloid and Surface Chemistry","Biochemistry","General Chemistry","Catalysis"],"day":"09","author":[{"last_name":"Wang","first_name":"Jinhua","full_name":"Wang, Jinhua"},{"first_name":"Tzuf Shay","last_name":"Peled","full_name":"Peled, Tzuf Shay"},{"first_name":"Rafal","last_name":"Klajn","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","full_name":"Klajn, Rafal"}],"title":"Photocleavable anionic glues for light-responsive nanoparticle aggregates","pmid":1,"publisher":"American Chemical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","scopus_import":"1","article_processing_charge":"No","publication":"Journal of the American Chemical Society"},{"status":"public","citation":{"chicago":"Bian, Tong, Ivan Lobato, Ji Wang, Tara A.

Various interactions have been employed to direct the crystallization of NPs, including van der Waals forces, hydrogen bonding, as well as electric and magnetic dipolar interactions. Among them, Coulombic interactions—ubiquitous in nature and the main driving force behind the formation of many minerals, such as fluorite or rock salt—have remained largely underexplored, owing to the rapid charge exchange between NPs bearing high densities of opposite charges (superionic NPs). Here, we worked with superionic NPs under conditions (room temperature, concentrated salt solutions) that preserved their native surface charge density. We demonstrate that under these conditions, the Coulombic interactions between superionic NPs are reminiscent of short-range intermolecular interactions. Our methodology was used to assemble oppositely charged NPs into high-quality superlattices exhibiting Catalan shapes. Depending on their size ratio, the NPs assembled into either rhombic dodecahedra or triakis tetrahedra with structures mimicking those of the ionic solids CsCl and Th3P4, respectively. We envision that the methodology described here can be applied to a wide range of charged NPs of various sizes, shapes, and compositions, thus facilitating the discovery of new nanomaterials.","lang":"eng"}],"day":"08","type":"preprint","month":"04","oa_version":"Preprint","author":[{"first_name":"Tong","last_name":"Bian","full_name":"Bian, Tong"},{"full_name":"Lobato, Ivan","first_name":"Ivan","last_name":"Lobato"},{"full_name":"Wang, Ji","first_name":"Ji","last_name":"Wang"},{"first_name":"Tara A.","last_name":"Nitka","full_name":"Nitka, Tara A."},{"full_name":"Peled, Tzuf Shay","first_name":"Tzuf Shay","last_name":"Peled"},{"full_name":"Lee, Byeongdu","first_name":"Byeongdu","last_name":"Lee"},{"full_name":"Van Aert, Sandra","last_name":"Van Aert","first_name":"Sandra"},{"first_name":"Sara","last_name":"Bals","full_name":"Bals, Sara"},{"full_name":"Vuković, Lela","last_name":"Vuković","first_name":"Lela"},{"last_name":"Altantzis","first_name":"Thomas","full_name":"Altantzis, Thomas"},{"last_name":"Král","first_name":"Petr","full_name":"Král, Petr"},{"last_name":"Klajn","first_name":"Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","full_name":"Klajn, Rafal"}],"date_created":"2023-08-01T09:30:08Z","title":"Catalan solids from superionic nanoparticles"},{"main_file_link":[{"url":"https://doi.org/10.1038/s42004-022-00658-8","open_access":"1"}],"date_published":"2022-03-30T00:00:00Z","oa":1,"publication_status":"published","citation":{"short":"O.

For example, the controlled aggregation of chromophores into discrete oligomers has been shown to tune their optical properties whereas encapsulation of reactive species within molecular hosts can increase their stability. The resazurin/resorufin pair has been widely used for detecting redox processes in biological settings; yet, how tight confinement affects the properties of these two dyes remains to be explored. Here, we show that a flexible Pd<jats:sup>II</jats:sup><jats:sub>6</jats:sub>L<jats:sub>4</jats:sub> coordination cage can efficiently encapsulate both resorufin and resazurin in the form of dimers, dramatically modulating their optical properties. Furthermore, binding within the cage significantly decreases the reduction rate of resazurin to resorufin, and the rate of the subsequent reduction of resorufin to dihydroresorufin. During our studies, we also found that upon dilution, the Pd<jats:sup>II</jats:sup><jats:sub>6</jats:sub>L<jats:sub>4</jats:sub> cage disassembles to afford Pd<jats:sup>II</jats:sup><jats:sub>2</jats:sub>L<jats:sub>2</jats:sub> species, which lacks the ability to form inclusion complexes – a process that can be reversed upon the addition of the strongly binding resorufin/resazurin guests. We expect that the herein disclosed ability of a water-soluble cage to reversibly modulate the optical and chemical properties of a molecular redox probe will expand the versatility of synthetic fluorescent probes in biologically relevant environments."}],"_id":"13347","year":"2022","quality_controlled":"1","doi":"10.1038/s42004-022-00658-8","publication_identifier":{"eissn":["2399-3669"]},"language":[{"iso":"eng"}],"keyword":["Materials Chemistry","Biochemistry","Environmental Chemistry","General Chemistry"],"article_number":"44","title":"Encapsulation within a coordination cage modulates the reactivity of redox-active dyes","day":"30","author":[{"first_name":"Oksana","last_name":"Yanshyna","full_name":"Yanshyna, Oksana"},{"first_name":"Michał J.","last_name":"Białek","full_name":"Białek, Michał J."},{"last_name":"Chashchikhin","first_name":"Oleg V.","full_name":"Chashchikhin, Oleg V."},{"id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","full_name":"Klajn, Rafal","last_name":"Klajn","first_name":"Rafal"}],"article_type":"original","scopus_import":"1","article_processing_charge":"No","publication":"Communications Chemistry","publisher":"Springer Nature","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"publication":"Journal of the American Chemical Society","scopus_import":"1","article_processing_charge":"No","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Chemical Society","title":"Altering the properties of spiropyran switches using coordination cages with different symmetries","author":[{"first_name":"Jinhua","last_name":"Wang","full_name":"Wang, Jinhua"},{"last_name":"Avram","first_name":"Liat","full_name":"Avram, Liat"},{"full_name":"Diskin-Posner, Yael","last_name":"Diskin-Posner","first_name":"Yael"},{"last_name":"Białek","first_name":"Michał J.","full_name":"Białek, Michał J."},{"first_name":"Wojciech","last_name":"Stawski","full_name":"Stawski, Wojciech"},{"last_name":"Feller","first_name":"Moran","full_name":"Feller, Moran"},{"first_name":"Rafal","last_name":"Klajn","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","full_name":"Klajn, Rafal"}],"day":"15","keyword":["Colloid and Surface Chemistry","Biochemistry","General Chemistry","Catalysis"],"language":[{"iso":"eng"}],"issue":"46","doi":"10.1021/jacs.2c08901","quality_controlled":"1","publication_identifier":{"eissn":["1520-5126"],"issn":["0002-7863"]},"_id":"13348","year":"2022","volume":144,"date_created":"2023-08-01T09:31:01Z","page":"21244-21254","date_updated":"2023-08-02T06:39:50Z","abstract":[{"text":"Molecular confinement effects can profoundly alter the physicochemical properties of the confined species. A plethora of organic molecules were encapsulated within the cavities of supramolecular hosts, and the impact of the cavity size and polarity was widely investigated. However, the extent to which the properties of the confined guests can be affected by the symmetry of the cage─which dictates the shape of the cavity─remains to be understood. Here we show that cage symmetry has a dramatic effect on the equilibrium between two isomers of the encapsulated spiropyran guests. Working with two Pd-based coordination cages featuring similarly sized but differently shaped hydrophobic cavities, we found a highly selective stabilization of the isomer whose shape matches that of the cavity of the cage. A Td-symmetric cage stabilized the spiropyrans’ colorless form and rendered them photochemically inert. In contrast, a D2h-symmetric cage favored the colored isomer, while maintaining reversible photoswitching between the two states of the encapsulated spiropyrans. We also show that the switching kinetics strongly depend on the substitution pattern on the spiropyran scaffold.

Here, we demonstrate rapid guest exchange between inclusion complexes of an open-window coordination cage that can simultaneously accommodate two guest molecules. Working with two types of guests, anthracene derivatives and BODIPY dyes, we show that the former can substantially modify the optical properties of the latter upon noncovalent heterodimer formation.

Chiral metasurfaces increase the electronic sensitivity to circular polarization, but their out-of-plane architecture entails manufacturing and performance trade-offs. Here, we show that nanoporous thin films of chiral nanoparticles enable high sensitivity to circular polarization due to light-induced polarization-dependent ion accumulation at nanoparticle interfaces. Self-assembled multilayers of gold nanoparticles modified with L-phenylalanine generate a photocurrent under right-handed circularly polarized light as high as 2.41 times higher than under left-handed circularly polarized light. The strong plasmonic coupling between the multiple nanoparticles producing planar chiroplasmonic modes facilitates the ejection of electrons, whose entrapment at the membrane–electrolyte interface is promoted by a thick layer of enantiopure phenylalanine. Demonstrated detection of light ellipticity with equal sensitivity at all incident angles mimics phenomenological aspects of polarization vision in marine animals. The simplicity of self-assembly and sensitivity of polarization detection found in optoionic membranes opens the door to a family of miniaturized fluidic devices for chiral photonics."}]},{"language":[{"iso":"eng"}],"issue":"21","keyword":["Materials Chemistry","Metals and Alloys","Surfaces","Coatings and Films","General Chemistry","Ceramics and Composites","Electronic","Optical and Magnetic Materials","Catalysis"],"quality_controlled":"1","doi":"10.1039/d1cc07081a","publication_identifier":{"issn":["1359-7345"],"eissn":["1364-548X"]},"article_processing_charge":"No","scopus_import":"1","article_type":"original","publication":"Chemical Communications","pmid":1,"publisher":"Royal Society of Chemistry","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Coexistence of 1:1 and 2:1 inclusion complexes of indigo carmine","day":"22","author":[{"first_name":"Oksana","last_name":"Yanshyna","full_name":"Yanshyna, Oksana"},{"full_name":"Avram, Liat","last_name":"Avram","first_name":"Liat"},{"full_name":"Shimon, Linda J.

However, it remains challenging to design physiologically stable self-assembling systems that demonstrate tunable and predictable behavior. Here, the use of zwitterionic tetrapeptide modalities to direct nanoparticle assembly under physiological conditions is reported. The self-assembly of gold nanoparticles can be activated by enzymatic unveiling of surface-bound zwitterionic tetrapeptides through matrix metalloprotease-9 (MMP-9), which is overexpressed by cancer cells. This robust nanoparticle assembly is achieved by multivalent, self-complementary interactions of the zwitterionic tetrapeptides. In cancer cells that overexpress MMP-9, the nanoparticle assembly process occurs near the cell membrane and causes size-induced selection of cellular uptake mechanism, resulting in diminished cell growth. The enzyme responsiveness, and therefore, indirectly, the uptake route of the system can be programmed by customizing the peptide sequence: a simple inversion of the two amino acids at the cleavage site completely inactivates the enzyme responsiveness, self-assembly, and consequently changes the endocytic pathway. This robust self-complementary, zwitterionic peptide design demonstrates the use of enzyme-activated electrostatic side-chain patterns as powerful and customizable peptide modalities to program nanoparticle self-assembly and alter cellular response in biological context.","lang":"eng"}],"date_updated":"2023-08-07T09:58:17Z","oa_version":"Published Version","type":"journal_article","month":"01","date_created":"2023-08-01T09:33:26Z","volume":34,"year":"2022","_id":"13355","publication_status":"published","oa":1,"main_file_link":[{"url":"https://doi.org/10.1002/adma.202104962","open_access":"1"}],"date_published":"2022-01-06T00:00:00Z","external_id":{"pmid":["34668253"]},"status":"public","citation":{"ama":"Huang RH, Nayeem N, He Y, et al.

These interactions can guide the assembly of charged nanoparticles into colloidal crystals of a quality previously only thought to result from their co-crystallization with oppositely charged nanoparticles of a similar size.

Herein, we describe the remote manipulation of native (non-photoresponsive) chiral plasmonic molecules (CPMs) using light. Our strategy is based on the use of a photoresponsive medium comprising a merocyanine-based photoacid. Upon exposure to visible light, the medium decreases its pH, inducing the formation of DNA triplex links, leading to a spatial reconfiguration of the CPMs. The process can be reversed simply by turning the light off and it can be repeated for multiple cycles. The degree of the overall chirality change in an ensemble of CPMs depends on the CPM fraction undergoing reconfiguration, which, remarkably, depends on and can be tuned by the intensity of incident light. Such a dynamic, remotely controlled system could aid in further advancing DNA-based devices and nanomaterials."}],"page":"5859-5863","date_created":"2023-08-01T09:35:06Z","volume":60},{"volume":7,"date_created":"2023-08-01T09:35:19Z","page":"23-37","oa_version":"Published Version","type":"journal_article","month":"01","date_updated":"2023-08-07T10:04:28Z","abstract":[{"text":"Dissipative self-assembly is ubiquitous in nature, where it gives rise to complex structures and functions such as self-healing, homeostasis, and camouflage. These phenomena are enabled by the continuous conversion of energy stored in chemical fuels, such as ATP. Over the past decade, an increasing number of synthetic chemically driven systems have been reported that mimic the features of their natural counterparts. At the same time, it has been shown that dissipative self-assembly can also be fueled by light; these optically fueled systems have been developed in parallel to the chemically fueled ones. In this perspective, we critically compare these two classes of systems. Despite the complementarity and fundamental differences between these two modes of dissipative self-assembly, our analysis reveals that multiple analogies exist between chemically and light-fueled systems.

Bacteriorhodopsin, for example, is a protein embedded within archaeal cell membranes that binds the chromophore retinal within its hydrophobic pocket. Exposure to light triggers regioselective photoisomerization of the confined retinal, which in turn initiates a cascade of conformational changes within the protein, triggering proton flux against the concentration gradient, providing the microorganisms with the energy to live. We are inspired by these functions in nature to harness light energy using synthetic photoswitches under confinement. Like retinal, synthetic photoswitches require some degree of conformational flexibility to isomerize. In nature, the conformational change associated with retinal isomerization is accommodated by the structural flexibility of the opsin host, yet it results in steric communication between the chromophore and the protein. Similarly, we strive to design systems wherein isomerization of confined photoswitches results in steric communication between a photoswitch and its confining environment. To achieve this aim, a balance must be struck between molecular crowding and conformational freedom under confinement: too much crowding prevents switching, whereas too much freedom resembles switching of isolated molecules in solution, preventing communication.\r\n\r\nIn this Account, we discuss five classes of synthetic light-switchable compounds—diarylethenes, anthracenes, azobenzenes, spiropyrans, and donor–acceptor Stenhouse adducts—comparing their behaviors under confinement and in solution. The environments employed to confine these photoswitches are diverse, ranging from planar surfaces to nanosized cavities within coordination cages, nanoporous frameworks, and nanoparticle aggregates. The trends that emerge are primarily dependent on the nature of the photoswitch and not on the material used for confinement. In general, we find that photoswitches requiring less conformational freedom for switching are, as expected, more straightforward to isomerize reversibly under confinement. Because these compounds undergo only small structural changes upon isomerization, however, switching does not propagate into communication with their environment. Conversely, photoswitches that require more conformational freedom are more challenging to switch under confinement but also can influence system-wide behavior.\r\n\r\nAlthough we are primarily interested in the effects of geometric constraints on photoswitching under confinement, additional effects inevitably emerge when a compound is removed from solution and placed within a new, more crowded environment. For instance, we have found that compounds that convert to zwitterionic isomers upon light irradiation often experience stabilization of these forms under confinement. This effect results from the mutual stabilization of zwitterions that are brought into close proximity on surfaces or within cavities. Furthermore, photoswitches can experience preorganization under confinement, influencing the selectivity and efficiency of their photoreactions. Because intermolecular interactions arising from confinement cannot be considered independently from the effects of geometric constraints, we describe all confinement effects concurrently throughout this Account."}],"date_updated":"2023-08-07T10:06:46Z","month":"11","oa_version":"Published Version","type":"journal_article","page":"2600-2610","date_created":"2023-08-01T09:35:50Z","volume":53,"language":[{"iso":"eng"}],"issue":"11","keyword":["General Medicine","General Chemistry"],"publication_identifier":{"issn":["0001-4842"],"eissn":["1520-4898"]},"quality_controlled":"1","doi":"10.1021/acs.accounts.0c00434","pmid":1,"publisher":"American Chemical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","scopus_import":"1","article_type":"original","publication":"Accounts of Chemical Research","day":"17","author":[{"full_name":"Grommet, Angela B.","last_name":"Grommet","first_name":"Angela B."},{"last_name":"Lee","first_name":"Lucia M.","full_name":"Lee, Lucia M."},{"id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","full_name":"Klajn, Rafal","first_name":"Rafal","last_name":"Klajn"}],"title":"Molecular photoswitching in confined spaces"},{"day":"04","author":[{"first_name":"Julius","last_name":"Gemen","full_name":"Gemen, Julius"},{"full_name":"Ahrens, Johannes","last_name":"Ahrens","first_name":"Johannes"},{"last_name":"Shimon","first_name":"Linda J.

For instance, the optical properties of BODIPY dyes are inherently related to the degree of aggregation and the mutual orientation of BODIPY units within these aggregates. Whereas the noncovalent aggregation of various BODIPY dyes has been studied in diverse media, the ill-defined nature of these aggregates has made it difficult to elucidate the structure–property relationships. Here, we studied the encapsulation of three structurally simple BODIPY derivatives within the hydrophobic cavity of a water-soluble, flexible PdII6L4 coordination cage. The cavity size allowed for the selective encapsulation of two dye molecules, irrespective of the substitution pattern on the BODIPY core. Working with a model, a pentamethyl-substituted derivative, we found that the mutual orientation of two BODIPY units in the cage’s cavity was remarkably similar to that in the crystalline state of the free dye, allowing us to isolate and characterize the smallest possible noncovalent H-type BODIPY aggregate, namely, an H-dimer. Interestingly, a CF3-substituted BODIPY, known for forming J-type aggregates, was also encapsulated as an H-dimer. Taking advantage of the dynamic nature of encapsulation, we developed a system in which reversible switching between H- and J-aggregates can be induced for multiple cycles simply by addition and subsequent destruction of the cage. We expect that the ability to rapidly and reversibly manipulate the optical properties of supramolecular inclusion complexes in aqueous media will open up avenues for developing detection systems that operate within biological environments.","lang":"eng"}],"page":"17721-17729","date_created":"2023-08-01T09:36:10Z","volume":142,"year":"2020","_id":"13362","publication_status":"published","oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1021/jacs.0c08589"}],"date_published":"2020-10-04T00:00:00Z","external_id":{"pmid":["33006898"]},"status":"public","citation":{"short":"J.
