Final Report Abstract

In summary, my scientific career has strongly profited from the funding and support within the Emmy Noether Program of the German Science Foundation. Within the first two years of funding (beginning January 2009) I got a call for the professorship of Structure and Properties of Polymeric Materials which I accepted in November 2010. I had the key advantage that my young researchers’ group consisting of PhD students and a lab technician moved with me from the University of Freiburg to the University of Stuttgart and helped me to set up the laboratories in Stuttgart. Hierarchical nanostructure control of polymer and polymer-hybrid materials has become one of the major topics in my research group and as outlined in the original proposal this means synthesis, self-assembly / crystallization on the nanometer scale, top-down patterning and establishment of structure-property relationships. Especially in terms of structural control we have published numerous approaches to control and direct structure formation, e.g. via solvent-vapor annealing techniques. Furthermore, my group has now in-depth experience in the characterization of functional properties, including absorption and electrochemical behavior, measurements of electronic transport (field-effect transistors and four-point-probe measurements) as well as of organic solar cells.
