Abstract

The origin of the excited states and the spectroscopic features of polar molecular films and crystals of N,N- dimethylaminobenzylidene 1,3-indandione (DMABI) was considered. The formation of charge transfer exciton states in the absorption and luminescence spectra by increase of the thicknesses of DMABI films was observed. The evidence of a strong exciton-phonon interaction and its effects on the exciton absorption and luminescence spectra was discovered. The coexistence of free and self-trapped excitons at elevated temperatures was found in DMABI films. The dynamics of both shallow short-lived and deeply trapped long-lived self-trapped exciton states in various films and crystal of DMABI was discussed.
