Research Interests

Our current studies are concerned with the photocatalytic water splitting in metallo-supramolecular coordination polygons and polyhedra as well as metal-organic coordination frameworks. Therefore, we self-assemble catalytic active transition metal complex fragments and (metal)organic photosensitizers in the presence of auxiliary ligand systems to obtain well defined photocatalysts. In the field of organic electronics we aim to prepare open-shell organic materials based on electron deficient chromophores like perylene bisimides, isoindigo derivatives or diketopyrrolopyrroles which are discussed to be suitable materials for versatile applications like electronic devices, non-linear optics or energy storage devices.

Background and Motivation

With a strong background in the synthesis of molecular metalorganic catalysts, our current efforts are focused on the controlled self-assembly of multidimensional metallosupramolecular architectures which should serve as artificial model systems for natural biocatalysts like the oxygen-evolving complex of photosystem II. Motivated by our knowledge on organic dye chemistry and reactive open-shell materials we additionally prepare highly functionalized chromophores with multiple radical centers for the fabrication of (opto)electronic and photovoltaic devices.
