Project Content
The project's goal is to develop and investigate inter- and intramolecular catalytic systems for the light-driven reduction of carbon dioxide. The photosensitizer and the catalytic units will be based on non-noble metal compounds, such as Cr, Mo or Cu in the first case and Fe, Co or Ni in the later. The catalytic performance will be determined in dependence of the used solvent, sacrificial electron donor and other relevant parameters. Photosensitizer-catalyst dyads with varying linker units will be synthesized as well. Mechanistic studies should provide more insight into the energy and electron transfer processes within the photocatalytic systems (inter- and intramolecular).
Tasks for Interns
Research placement involves an organic and inorganic synthesis of metal complexes built up of macrocyclic ligands with a different sulfur-containing donor set. Investigations on the catalytic properties of the complexes in the CO2 activation will be of high priority.
