Photo-Induced Charge Separation in a Blend of Perylenediimide and Hexabenzocoronene Derivatives Studied by FP-TRMC

Photo-induced charge separation has been monitored in a spin-coated blend of hexabenzocoronene and perylene-diimide derivatives using the electrodeless flash-photolysis time-resolved microwave conductivity technique (FP-TRMC). Evidence is found for a direct charge-transfer transition between the components at longer wavelengths.
