Electric-field effects on fluorescence decay profile have been measured for each fluorescence component of the methylene-linked compound of pyrene, i.e., 1,3-bis-(1-pyrenyl)propane, in a polymer film at a high concentration. It is shown that the field-induced change in fluorescence intensity of the linked compound mainly arises from the field-induced change in initial population of the emitting states. The field-induced decrease in initial population both of the S1 state of pyrene chromophore and of the emitting state of the sandwich type of excimer is attributed to the field-induced charge separation. The efficient charge transport following the field-induced charge separation of the sandwich type excimer is related to the efficient generation of electroluminescence in the methylene-linked compound of pyrene.
