Copper-phthalocyanine based metal-organic interfaces: The effect of fluorination, the substrate, and its symmetry

Abstract

Metal-organic interfaces based on copper-phthalocyanine monolayers are studied in dependence of the metal substrate (Au versus Cu), of its symmetry hexagonal (111) surfaces versus fourfold (100) surfaces, as well as of the donor or acceptor semiconducting character associated with the nonfluorinated or perfluorinated molecules, respectively. Comparison of the properties of these systematically varied metal-organic interfaces provides new insight into the effect of each of the previously mentioned parameters on the molecule-substrate interactions. © 2010 American Institute of Physics.
