Abstract

Abstract 1-Pyrenylmethyl 9-anthracenecarboxylate exhibits an intramolecular exciplex emission. The electron transfer from the pyrene to the anthracenecarboxylate chromophore has been shown by the effects of solvent and temperature on the fluorescence spectra to drive the formation of the exciplex in spite of the unfavorable s-cis conformation of the carboxylate C–O bond.
