Abstract

The adsorption configurations of copper phthalocyanine (CuPc) molecules on platinum-modified Ge(001) have been studied using scanning tunneling microscopy. After deposition at room temperature and cooling down to 77 K the CuPc molecules are still dynamic. However, after annealing at 550±50 K, the adsorption configurations of the CuPc molecules change and the CuPc molecules do not exhibit any dynamics at 77 K. This is indicative of a transition from a physisorbed to a chemisorbed state. We suggest that during annealing, the CuPc molecule binds with the substrate dimers via a cycloaddition reaction. Atomic models are proposed for the different adsorption configurations
