text: The architecture of self-assembled host molecules can profoundly affect the
properties of the encapsulated guests. 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”.

text: Photoisomerization of azobenzenes from their stable E isomer to the metastable
Z state is the basis of numerous applications of these molecules. 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.

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. However, to what extent the properties of such supramolecular
crystals actually resemble those of atomic materials often remains unclear. Here,
we present coarse-grained molecular simulations explicitly demonstrating how a
behavior evocative of that of semiconductors may emerge in a colloidal superlattice.
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.

text: 'Integrating light-sensitive molecules within nanoparticle (NP) assemblies
is an attractive approach to fabricate new photoresponsive nanomaterials. 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.'

text: The self-assembly of inorganic nanoparticles (NPs) into ordered structures
(superlattices) has led to a wide range of nanomaterials with unique optical,
magnetic, electronic, and catalytic properties. 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.

text: Confining molecules within well-defined nanosized spaces can profoundly alter
their physicochemical characteristics. 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
PdII6L4 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 PdII6L4
cage disassembles to afford PdII2L2
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.

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. This finding was used to fabricate a time-sensitive
information storage medium with tunable lifetimes of the encoded messages.

text: Confinement within molecular cages can dramatically modify the physicochemical
properties of the encapsulated guest molecules, but such host-guest complexes
have mainly been studied in a static context. Combining confinement effects with
fast guest exchange kinetics could pave the way toward stimuli-responsive supramolecular
systems—and ultimately materials—whose desired properties could be tailored “on
demand” rapidly and reversibly. 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. We
also studied the light-induced covalent dimerization of encapsulated anthracenes
and found large effects of confinement on reaction rates. By coupling the photodimerization
with the rapid guest exchange, we developed a new way to modulate fluorescence
using external irradiation.

text: Optoelectronic effects differentiating absorption of right and left circularly
polarized photons in thin films of chiral materials are typically prohibitively
small for their direct photocurrent observation. 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.

text: We show that the optical properties of indigo carmine can be modulated by
encapsulation within a coordination cage. Depending on the host/guest molar ratio,
the cage can predominantly encapsulate either one or two dye molecules. The 1 : 1
complex is fluorescent, unique for an indigo dye in an aqueous solution. We have
also found that binding two dye molecules stabilizes a previously unknown conformation
of the cage.

text: 'Supramolecular self-assembly in biological systems holds promise to convert
and amplify disease-specific signals to physical or mechanical signals that can
direct cell fate. 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.'

text: 'Self-assembly of nanoparticles can be mediated by polymers, but has so far
led almost exclusively to nanoparticle aggregates that are amorphous. Here, we
employed Coulombic interactions to generate a range of composite materials from
mixtures of charged nanoparticles and oppositely charged polymers. The assembly
behavior of these nanoparticle/polymer composites depends on their order of addition:
polymers added to nanoparticles give rise to stable aggregates, but nanoparticles
added to polymers disassemble the initially formed aggregates. The amorphous aggregates
were transformed into crystalline ones by transiently increasing the ionic strength
of the solution. The morphology of the resulting crystals depended on the length
of the polymer: short polymer chains mediated the self-assembly of nanoparticles
into strongly faceted crystals, whereas long chains led to pseudospherical nanoparticle/polymer
assemblies, within which the crystalline order of nanoparticles was retained.'

text: Coulombic interactions can be used to assemble charged nanoparticles into
higher-order structures, but the process requires oppositely charged partners
that are similarly sized. The ability to mediate the assembly of such charged
nanoparticles using structurally simple small molecules would greatly facilitate
the fabrication of nanostructured materials and harnessing their applications
in catalysis, sensing and photonics. Here we show that small molecules with as
few as three electric charges can effectively induce attractive interactions between
oppositely charged nanoparticles in water. 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. Transient nanoparticle assemblies can be generated using positively
charged nanoparticles and multiply charged anions that are enzymatically hydrolysed
into mono- and/or dianions. Our findings demonstrate an approach for the facile
fabrication, manipulation and further investigation of static and dynamic nanostructured
materials in aqueous environments.

text: DNA nanotechnology offers a versatile toolbox for precise spatial and temporal
manipulation of matter on the nanoscale. However, rendering DNA-based systems
responsive to light has remained challenging. 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.

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. We hope
that these considerations will facilitate further development of the field of
dissipative self-assembly.

text: 'Inorganic nanoparticles (NPs) exhibit a wide range of fascinating physicochemical
properties, many of which can be controlled by modulating the NP–NP coupling.
Controlling the self-assembly of NPs using light has traditionally been achieved
by functionalizing their surfaces with monolayers of photoswitchable molecules,
which can be reversibly isomerized between two or more states upon exposure to
different wavelengths of light. NPs whose assembly can be controlled by light
in a reversible fashion can find interesting applications. The chapter deals with
systems comprising mixtures of non-photoswitchable NPs and small-molecule photoacids
and photobases. Examples of light-controlled self-assembly of NPs hitherto reported
have been categorized into six distinct approaches. These are: functionalizing
NPs with monolayers of photoswitchable molecules, light-controlled adsorption/desorption
of photoswitchable molecules onto NPs, and light-induced electron transfer between
the particle''s inorganic core and the NP-bound ligands.'

text: "In nature, light is harvested by photoactive proteins to drive a range of
biological processes, including photosynthesis, phototaxis, vision, and ultimately
life. 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."

text: Aggregation of organic molecules can drastically affect their physicochemical
properties. 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.
