[{"abstract":[{"lang":"eng","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."}],"intvolume":"         8","publication_status":"published","publication_identifier":{"issn":["2451-9308"],"eissn":["2451-9294"]},"oa_version":"Published Version","title":"Ternary host-guest complexes with rapid exchange kinetics and photoswitchable fluorescence","author":[{"last_name":"Gemen","full_name":"Gemen, Julius","first_name":"Julius"},{"full_name":"Białek, Michał J.","last_name":"Białek","first_name":"Michał J."},{"last_name":"Kazes","full_name":"Kazes, Miri","first_name":"Miri"},{"last_name":"Shimon","full_name":"Shimon, Linda J.W.","first_name":"Linda J.W."},{"full_name":"Feller, Moran","last_name":"Feller","first_name":"Moran"},{"first_name":"Sergey N.","last_name":"Semenov","full_name":"Semenov, Sergey N."},{"full_name":"Diskin-Posner, Yael","last_name":"Diskin-Posner","first_name":"Yael"},{"first_name":"Dan","last_name":"Oron","full_name":"Oron, Dan"},{"first_name":"Rafal","last_name":"Klajn","full_name":"Klajn, Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b"}],"scopus_import":"1","day":"08","article_type":"original","date_created":"2023-08-01T09:32:14Z","volume":8,"language":[{"iso":"eng"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","issue":"9","citation":{"ieee":"J.

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."}],"intvolume":"         7","month":"01","citation":{"mla":"Weißenfels, Maren, et al. “Dissipative Self-Assembly: Fueling with Chemicals versus Light.” <i>Chem</i>, vol. 7, no. 1, Elsevier, 2021, pp. 23–37, doi:<a href=\"https://doi.org/10.1016/j.chempr.2020.11.025\">10.1016/j.chempr.2020.11.025</a>.","apa":"Weißenfels, M., Gemen, J., &#38; Klajn, R.
