Interface properties of polar phthalocyanines on silver substrates — •Małgorzata Polek, Fotini Petraki, Florian Latteyer, Heiko Peisert, and Thomas Chassé — University of Tuebingen, Institute of Physical Chemistry, Auf der Morgenstelle 18, 72076 Tuebingen, Germany
Phthalocyanines (Pcs) are promising materials for various devices like light-emitting diodes, field effect transistors and solar cells. In this context, polar Pcs are of particular interest, e.g. due to their different growth properties and the variation of the chemical reactivity. Chemical reactions at interfaces could be a route for the tuning of both electronic interface properties and the molecular orientation.
We study interface properties between polar Pcs and silver using X-ray photoelectron spectroscopy (XPS), Ultraviolet photoelectron spectroscopy (UPS) as well as optical spectroscopies. We focus on VOPc, VOPcF16, GaClPc and AlClPc. For some interfaces a clear indication for a chemical interaction was found.
