Abstract

A complex experimental study of Cu(2p3/2), Cu(2p1/2) photoelectron and Kα1,2 and Lα1,2 X-ray emission spectra of copper in copper phthalocyanine CuPcH16 and its fluoro-substituted analog CuPcF16 is carried out. A charge transfer model is used to interpret the spectra. It is shown that Kα1 and Kα2 lines of the spin-doublet of copper have a complex structure due to the processes of metal-to-ligand charge transfer. The role of a satellite in the formation of emission lines is revealed.
