Temperature dependence of excimer formation and dissociation in poly(N-vinylcarbazole)

Abstract

The fluorescence from a solution of poly(N-vinylcarbazole) has been examined over the temperature range 200–295 K, using time-resolved and steady-state fluorescence spectroscopy. At all temperatures the emission could be best described by a three-component fluorescence decay function, the derived lifetimes being assigned to three independent excimer groups. Some conclusions are drawn concerning the origins, interconversion between, and dissociation of, these species.
