Magnetic transition metal (MTM) phthalocyanines are regarded as objects for the development of low dimensional molecular magnets because they are assumed as possible candidates for potential applications in high-density information storage and quantum computers that gives a strong motivation to characterize and study the electronic structure of MTM phthalocyanine thin films. Moreover this determines also the performance of devices. In this presentation we report the results of extensive investigations of the electronic structure: core-levels and valence band of the organic semiconductors CoPc and FePc in situ grown on Au(001) surface under UHV conditions. The studies were performed by means of direct and resonant photoemission, NEXAFS and DFT calculations. The experimentally obtained electronic states appeared to be in very good agreement with DFT calculations. This work was supported by the DFG under grant no. 436RUS17/52/06 and through the DFG Priority Program 1165., by the SMWK and by RFBR (grant no. 08-02-01170).
