Investigation of the electronic structure of cobalt phthalocyanine films on MnO substrates by X-ray Photoemission Spectroscopy — •Mathias Glaser, Heiko Peisert, and Thomas Chassé — Instit für Physikalische und Theoretische Chemie, Universität Tübingen, Auf der Morgenstelle 18, 72076 Tübingen

Interactions at the interface between transition metal phthalocyanines (TMPc) and metal substrates affect electronic properties of adsorbed organic molecules in many cases [1,2]. Besides metals, transition metal oxide thin films are promising substrates for applications of TMPcs; studies of these interfaces however are rare. It is known that epitaxially grown ultrathin transition metal oxide films on metals show unique chemical physical properties depending e.g. on the film thickness [3,4]. In addition, charging effects in photoemission can be avoided. In this work we investigate the electronic structure of cobalt phthalocyanine on MnO ultrathin films epitaxially grown on Ag(001) using x-ray photoelectron spectroscopy.
