Abstract

The dependence of spectral properties and interfragmental charge transfer (ICT) on excitation, relaxa­tion and excited state deactivation of 2-(3-coumaroyl)-benzopyrylium perchlorates has been analyzed. It was found that the positions of emission bands and rate constants of radiationless deactivation line­arly correlate with ICT upon excited state deactivation, and Stokes' shifts of fluorescence demonstrate linear dependence on ICT upon structural relaxation in the excited state.
