Abstract
The photophysical processes and photochemical reactions of 4-[(E)-2-(2,3,5,6,8,9,11,12,14,15-decahydro-1,4,7,10,13,16-benzohexaoxacyclooctadecyn-18-yl)vinyl]-1-ethylpyridinium perchlorate and its complexes with cucurbit[7]uril in water in the absence and in the presence of lead perchlorate were studied by absorption, luminescence, and laser kinetic spectroscopy. Intersystem crossing to the triplet state and trans—cis-photoisomerization of the dye were established. The formation of an inclusion complex of the dye with cucurbit[7]uril was found.
