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."}],"scopus_import":"1","date_published":"2019-10-10T00:00:00Z","page":"2398-2407","external_id":{"pmid":["31666874"]},"oa_version":"Published Version","keyword":["Organic Chemistry"],"_id":"13369","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3762/bjoc.15.232"}],"intvolume":"        15","title":"Reversible switching of arylazopyrazole within a metal–organic cage","publisher":"Beilstein Institut","publication_identifier":{"eissn":["1860-5397"]},"citation":{"ama":"Hanopolskyi AI, De S, Białek MJ, et al.
