Energy transfer between polystyrene donor and 2,5-diphenyloxazole (PPO) species incorporated as intramolecular energy traps has been studied by time-resolved luminescence spectroscopic techniques. It is demonstrated that the extent of energy transfer from excimeric species is negligible compared to that from unassociated (or monomeric) excited-state donors. The results implicate singlet energy migration in determination of the photophysical characteristics of polystyrene and in intramolecular energy trapping in polymers based on styrene derivatives. © 1983 American Chemical Society.
