The observed photo processes include dimerization, E-Z isomerization, and intersystem crossing to the triplet state, as well as the complexation [(E,E)-1](ClO4)2 with cucurbit[7]uril (CB[7]). The [(E,E)-1](ClO4)2 dye dimerization was shown to be energetically more favorable in the excited state than in the ground state. The reversible photoinduced migration of the dye dication in the CB[7] cavity takes place as a result of partial exit of the [(E,E)-1]2+ from the cavity and its subsequent conversion to the (E,Z)-isomer in the excited state, which undergoes conversion to the initial complex of {[(E,E)-1]@CB[7]}2+ after returning to the ground state. This photoprocess is of interest in relation to the scientific problem of designing photocontrolled supramolecular machines.<\/jats:p>","DOI":"10.3390\/molecules31091464","type":"journal-article","created":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T15:09:33Z","timestamp":1777388973000},"page":"1464","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prospects for the Creation of a Photocontrolled Supramolecular Machine Based on a 1,4-Di(azastyryl)benzene Derivative and Cucurbit[7]uril"],"prefix":"10.3390","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3739-1693","authenticated-orcid":false,"given":"Levon S.","family":"Atabekyan","sequence":"first","affiliation":[{"name":"NRC \u201cKurchatov Institute\u201d, Academician Kurchatov Square 1, 123182 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vitaly G.","family":"Avakyan","sequence":"additional","affiliation":[{"name":"NRC \u201cKurchatov Institute\u201d, Academician Kurchatov Square 1, 123182 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0915-7894","authenticated-orcid":false,"given":"Vyacheslav N.","family":"Nuriev","sequence":"additional","affiliation":[{"name":"NRC \u201cKurchatov Institute\u201d, Academician Kurchatov Square 1, 123182 Moscow, Russia"},{"name":"Department of Chemistry, M.
