Overview

The focus of our research are 3d metal ions, especially their interaction with (reactive) oxygen species.  One of our research interests includes multinuclear complexes as potential catalysts in multielectron transfer reactions. Here, we seek to understand the cooperative effects of metal ions to establish a structure-function relationship for the development of new homogeneous catalysts.  Additionally, we are focusing on reactive intermediates formed in copper complexes.

Another research field is located in metalloneurochemistry. Here, we are developing metal specific chelators and fluorescent sensors to explore the metabolic pathways of (especially) endogeneous zinc ions.

Chosen research areas:

  • Multinuclear catalysts can store more than one redox equivalent, which makes them promising candidates for the catalysis of complex redox reactions.... read more
  • Fluorescent sensors and chelators are important tools in metalloneurochemistry to study the role of endogeneous inorganic species such as 3d metal ions in the central nervous system....
