Charge transfer at phthalocyanine heterojunctions — •Susi Lindner, Benjamin Mahns, and Martin Knupfer — IFW Dresden, P.O. Box 270116, 01171 Dresden

Motivated by interesting electronic and magnetic properties of organic semiconductors like transition metal phthalocyanines we studied the organic-organic interfaces of CoPc, F16CoPc and MnPc on various metal substrates (Au and Ag) by means of x-ray and ultra violet photoemission spectroscopy. We show that a charge transfer can be achieved at the interface between this well known molecules. Additionally, in this effect the transition metal center is mainly involved resulting in oxidized Mnδ+Pc and reduced F16Coδ−Pc, as well as Coδ−Pc species.

This project is supported by the DFG (KN 393/14).
