摘要

Photophysical and photochemical processes in diperchlorates of styryl dyes containing an N-ammonioalkyl substituent have been studied by the absorption, luminescence, and laser kinetic spectroscopy techniques. Participation of the triplet state in photoexcitation energy degradation processes and the ability of the dyes to enter the trans-cis photoisomerization reaction have been revealed. Dimerization and delayed fluorescence of the dyes at 77 K have been detected.
