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 Rhenium bipyridine-functionalized Polythiophenes can be used as heterogeneous catalysts for CO 2 -reduction.Carbon Dioxide: A Greenhouse Gas.- Carbon Capture and Storage.- Setup for Electropolymerization/Electrolysis.- Chemical Synthesis of Pyridine-functionalized and Rhenium bipyridine-functionalized Thiophenes. Melanie Weichselbaumer obtained her Master´s Degree under the supervision of Univ. Prof. Mag. Dr. DDr. h.c. N. S. Sariciftci at University of Linz, Austria.
