Preparation of organic thin films from solution on metal templates — •Stephan Wenzel, Norman Schmidt, George Tzvetkov, and Rainer Fink — Physikal. Chemie 2, Universität Erlangen, Egerlandstr.3,91058 Erlangen

The preparation of well ordered organic nanostructures is an interesting topic with respect to potential applications in photonic crystals. We have started with a comprehensive study to investigate the formation of well-ordered and well-oriented organic nanostructures using metallic microstructures on inert surfaces when the organic substance is deposited from solution. Emphasis is lying on the effect of reduced template sizes on the growth of particular crystallites upon slow evaporation of the solvent. We employed various molecular substances which are attractive for optical investigations. The formation of crystallites is characterized in-situ by light microscopy and ex-situ by UV photoelectron emission microscopy (PEEM) and scanning transmission x-ray microspectroscopy (STXM). The latter is used to investigate the orientation of the microcrystallites from the linear NEXAFS dicroism which is accessible at the recently installed PolLux beamline at the Swiss Light Source. The project is funded by the BMBF under contract 05/KS4WE1/6.
