Paper Abstract

A problem of kinetic fluorescence and emission anisotropy decays of the intramolecular charge transfer (ICT and TICT) compounds in polar and non-polar (but highly polarizable) solvents will be discussed. It will be shown that the application of appropriate kinetic approximations (high- and low-temperature approximations) enables a direct determination of the kinetic rates describing the two-excited-state processes. Experimental examples for DMABN (4-(dimethyl amino) benzonitrile) and related compounds will be compared. A problem of TICT (Twisted Intramolecular Charge Transfer) mechanism will be discussed. The discussion will be supported by considering the emission anisotropy decays of DMABN in the solvents of different viscosity and which provide further evidence for TICT mechanism in DMABN and related compounds.
