摘要

A novel organic electron accepter, N,N'-dipyrimidinyl-3,4,9,10-perylene-tetracarboxylic diimide (DMP), was designed and synthesized.The molecular structure was characterized by FTIR spectrum and ele-mental analysis.By cyclic voltammetry measurements, DMP was found to possess a lower LUMO en-ergy level than N,N'-diphenyl-3,4,9,10-perylene-tetracarboxylic diimide due to the stronger elec-tron-withdrawing pyrimidinyl group than the phenyl group.Fluorescence quenching is observed in a dual-layer film consisting of a DMP layer and a C60 layer and was attributed to the charge transfer at the interface due to the energy level offset between DMP and C60.
