Energy Transfer in Poly(vinyl toluene)

Abstract

An investigation of host‐sensitized energy transfer in poly(vinyl toluene) doped with p‐terphenyl and diphenylstilbene is reported, along with a study of energy transfer from p‐terphenyl to diphenylstilbene in the poly(vinyl toluene) host. The results indicate that excitons can migrate in poly(vinyl toluene) and that excimer‐forming sites and p‐terphenyl molecules act as exciton traps. Both of these kinds of traps can transfer their energy to diphenylstilbene by radiative reabsorption and by long‐range resonant interaction.
