Our research is driven by the development of new sustainable processes in organic synthesis and their application to control functions in materials on the molecular level.
Under this scheme we are developing new catalytic processes based on bidentate Lewis acid, such as the inverse electron-demand Diels-Alder reaction.
Furthermore, we are looking for new ways of controlling structures with molecular switches and use this knowledge to create “smart” responsive materials, e.g. macrocylic oligoazobenzenes or switchable peptides.
We are also interested in new concepts to build polycyclic (hetero-) aromatic structures as materials for molecular electronics or other applications.

In the publikation with the title "Combining Bidentate Lewis Acid Catalysis and Photochemistry: Formal Insertion of o-Xylene into an Enamine Double Bond" a new reaction pathway for o-quinodimethane derivatives upon irradiation with blue LEDs is presented.
The Wegner group welcomes its new new bachelor candidate Conrad Averdunk.
From February, 1st until April 30th, 2019, Assoc. Prof. Yakimova stayed at the Justus-Liebig University Giessen under the DAAD program Stimuli-responsive macrocyclic assembly induced by complexation of molecular switches.
In collaboration with the group of Prof. Lars H. Andersen "Action-spectroscopy studies of positively charge-tagged azobenzene in solution and in the gas-phase" were conducted. Our results were published in the Journal of Chemical Physics. The investigation demonstrates the potential of this technique to provide the intrinsic absorption properties of the ammonium-tagged azobenzene.
Recently, Burns and co-workers reported the successful implementation of the air-stable catalyst complex of 9,10-dimethyl-9,10-diboraanthracene with pyridazine in their total synthesis of azamerone.
