We report photoemission measurements using synchrotron radiation for a series of metal-free and copper benzo-annelated porphyrazines, respectively. Such systems of molecules allow to investigate the evolution of the electronic structure with the increasing π-electron system of the molecule. For the copper set of compounds information about metal-to-ligand and ligand-to-metal charge transfer processes are inferred from the ratios between the copper satellites and main lines. The results are discussed for both the Cu2p and valence regions of the photoemission spectra.
