Photoelectron spectroscopy is a powerful tool for probing the electronic structure of organic materials. A major concern in such studies is sample degradation under light irradiation. Here, we investigate the electronic structure of CuPc on TiSe2 using angle-resolved photoelectron spectroscopy, with particular emphasis on X-ray–induced degradation. Our results show that the degradation rate depends strongly on the substrate, even for identical molecules, and we discuss the resulting effect on the interfacial electronic properties.
