Abstract
Photoprocesses in bis(18-crown-6)-1,4-distyrylbenzene (DSB) and its complexes with potassium, barium, and lead perchlorates have been studied in MeCN solutions by absorption, luminescent, and laser kinetic spectroscopy. The DSB molecules in the triplet state participate in the degradation of electron excitation energy, cis–trans isomerization, and fluorescence. The triplet–triplet absorption spectrum has several maximums in the range of 500–700 nm. The most efficient intersystem crossing to the triplet state is observed for the lead perchlorate complex, which is accompanied by a drop in the fluorescence quantum yield and the absence of trans–cis isomerization.
