摘要：

X-ray photoelectron spectra of 4,4'-bis(4 styryl-styryl) benzene oligomer (4PV) films metallized with chromium and aluminum films were used to investigate the nature of 4PV-metal interfacial reactions. The changes in the core level spectra of carbon, metal, and oxygen indicated the formation of a carbide in a chromium covered oligomer and a metal-oxide carbon and/or carbide in aluminum covered films. Yet no apparent reaction was observed in the interfacial layer when depositing the oligomer film on the chromium layer. These reactions are used as a possible explanation for the electrical characteristics of diodes made from these materials. (C) 1997 American Institute of Physics.
