Here, we investigated the behavior of a model arylazopyrazole in the presence of a self-assembled cage based on Pd–imidazole coordination. Owing to its high water solubility, the cage can solubilize the E isomer of arylazopyrazole, which, by itself, is not soluble in water. NMR spectroscopy and X-ray crystallography have independently demonstrated that each cage can encapsulate two molecules of E-arylazopyrazole. UV-induced switching to the Z isomer was accompanied by the release of one of the two guests from the cage and the formation of a 1:1 cage/Z-arylazopyrazole inclusion complex. DFT calculations suggest that this process involves a dramatic change in the conformation of the cage. Back-isomerization was induced with green light and resulted in the initial 1:2 cage/E-arylazopyrazole complex. This back-isomerization reaction also proceeded in the dark, with a rate significantly higher than in the absence of the cage."}],"date_created":"2023-08-01T09:38:06Z","year":"2019","scopus_import":"1","oa":1,"intvolume":"        15","citation":{"chicago":"Hanopolskyi, Anton I, Soumen De, Michał J Białek, Yael Diskin-Posner, Liat Avram, Moran Feller, and Rafal Klajn. “Reversible Switching of Arylazopyrazole within a Metal–Organic Cage.” <i>Beilstein Journal of Organic Chemistry</i>.
