Abstract
Fluorescence, phosphorescence and thermally activated delayed fluorescence of tetrachlorophthalic anhydride-hexamethylbenzene charge-transfer crystal have been studied, under photostationary and transient conditions, in a wide temperature range (1.7–300 K). The rate constants for various radiative and non-radiative processes have been determined within the framework of a photokinetic model, which is considered to be a typical one for those charge-transfer crystals which are characterized by very high charge-transfer character of the lowest triplet state (charge-transfer triplet excitons).
