Abstract

We overview our experimental work on exciton self-trapping in simple organic molecular crystals. First we show pressure-induced change in the exciton-phonon interaction, indicating that the interaction depends strongly on the intermolecular distance, and then we demonstrate the experimental results and compare them with theoretical results on the exciton-phonon coupling constants, presence of the self-trapping barrier, intermediate self-trapped exciton states, the radiative annihilation of excitons at the exit of the self-trapping path. Most of this paper is devoted to show exciton relaxation processes visualized in time-resolved luminescence in Pyrene.
