GENERAL RESEARCH INTERESTS

Polyoxometalates The research activity of the Kortz group is in the field of synthetic inorganic and organometallic chemistry. We are particularly interested in the preparation and structural characterization of discrete polynuclear metal-oxo complexes called polyoxometalates (POMs). POMs have a tremendous structural variety and interesting properties in different fields including catalysis, energy, environment, medicine and materials science. The multitude of potential applications has led to significant interest in POMs worldwide. The first POM was prepared almost two centuries ago by Berzelius (1826), but it could be structurally characterized only 100 years later by Keggin (1933). Especially the availability of single-crystal X-ray diffraction has led to the discovery of a large number of novel POMs with different shape, size, and composition.

Cu20-144
The research activities of the Kortz group at Jacobs University Bremen are mainly focused on (a) transition metal-substituted POMs, (b) hybrid organic-inorganic POMs, and (c) noble metal-based POMs. POMs are synthesized and structurally characterized at Jacobs University Bremen using a multitude of state-of-the art solution and solid-state analytical techniques (e.g. NMR, XRD, IR, UV-vis, AA, TGA-DSC). The catalytic, magnetic, biomedical, and electrochemical properties of the novel compounds are also investigated, at times involving expert colleagues from around the world. The Kortz group also has several industrially sponsored research projects in the areas of catalysis, energy, and environmental applications.

In 2008 the Kortz group discovered polyoxopalladates(II), a class of POMs based exclusively on square-planar coordinated Pd2+ addenda (as opposed to classical POMs, which are based on early d-block metal ions in high oxidations states). In 2010 the Kortz group also discovered polyoxoaurates(III). In 2005 the Kortz group discovered Cu20P8W48, a pioneering result demonstrating chemical reactivity of the large, wheel-shaped P8W48.
