Melanie Weichselbaumer presents the synthesis of the monomers as well as the electropolymerization on Pt-electrodes. The electrolysis experiments were carried out for 40 hours and the products were analysed by gas chromatography and ionic chromatography. Pyridine-functionalized and Rheniumbipyridine-functionalized Polythiophenes can be used as heterogeneous catalysts for CO2 reduction.
