Abstract

Ultrafast exciton dynamics in polycrystalline films of dipolar N,N-dimethylaminobenzylidene 1,3-indandione (DMABI) molecules was studied by femtosecond luminescence upconversion and transient absorption techniques. An enhanced nonradiative relaxation of the excitons, taking place on the subpicosecond time scale, was observed. It was attributed to the initial localisation and thermalisation of the self-trapped excitons. One-dimensional exciton-exciton annihilation was observed under high excitation conditions.
