    Günter Reiter is professor for experimental polymer physics at the physics institute of the University of Freiburg. He is a member of the board of directors of the Freiburger Materialforschungszentrum and speaker of the International Research Training Group on Soft Matter Science, a collaboration between Strasbourg, Mulhouse, Basel and Freiburg. He is chairman of the Macromolecular Physics Section of the Condensed Matter Division of the European Physical Society. He has previously been Editor-in-Chief of The European Physical Journal E Soft Matter and is now Editor for The European Physical Journal Special Topics (EPJ ST) and Book Series Editor (with David Andelman) for the Series in Soft Condensed Matter published by World Scientific, Singapore.

    He studied physics in Graz/Austria, where he received his PhD in 1987. After five years at the MPI for Polymer Research in Mainz/Germany and two years at the University of Illinois in Urbana-Champaign/USA, he stayed 14 years in Mulhouse/France as a researcher at the CNRS. In 2008 he accepted his current position in Freiburg.

    His research interests are covering questions on the behavior and properties of polymers at interfaces, phase transitions and growth processes in complex systems, and molecular self-assembly and the formation of functional structures on surfaces.


    Orienting semi-crystalline conjugated polymers through dewetting and nucleation control

    Low cost solution processing coupled with high-performance opto-electronic properties make semi-crystalline π-conjugated polymers key materials in the development of organic electronic technology such as transistors, light emitting diodes and photovoltaic cells.
    The aim of this project is to generate model systems comprising large arrays of oriented and partially crystalline domains of semiconducting polymers like polythiophenes. The formation of large aligned domains will allow establishing detailed and predictive correlations between specific aspects of molecular order and opto-electronic properties. In view of a potential applicability, we intend to obtain such model systems by developing approaches based on dewetting and self-organization processes. Our central goal is to unveil the underlying physical processes both concerning the ordering processes and the resulting electronic properties of such oriented polymer structures. To this end, we will develop pathways to control the kinetics of molecular organization and the degree of order, based on techniques like dewetting, nucleation and growth and related self-organization processes controlled via appropriate deformation of the polymeric chains (e.g. by rubbing or stretching) and directed by specific interactions with appropriate substrates.
