Research Topics

Synthesis and investigation of new coordination compounds (complexes) including organo-metallic derivatives. Coordination units (or building block) carrying specific properties are embedded in mononuklear, binuclear, polynuclear complexes, coordination polymers or hybrid materials. Design of polydentate ligands is essential to this approach.

Specific properties such as reactivity in the ligand sphere, activation of ligands, redox chemistry at the metal(s) or the ligand(s), electron transfer, luminescence, photochemistry, formation of stable radicals, magnetism etc. define potential applications of such materials. Variation of metal(s) and ligand(s) in combination with suitable structural and spectroscopic Methods allow drawing structure-property relations for optimisation. Electrochemical and spectroelectrochemical methods are a stronghold of the work.

Potential applications of the coordination units:

  • Mono- and oligonuclear complexes for (electro)catalysis
  • Strongly luminescent materials
  • Transition metal complexes with cytotoxic (antiproliferative) properties
  • Precursor complexes for the deposition (CVD, ALD) of metals or metal chalkogenides, metal pnictides etc.
  • Coordination polymers as electroactive (semiconducting) materials

Ongoing research projects:

  • Organonickel complexes with relevance to C‒C cross coupling catalysis (DFG project KL 1194/15-1)
  • Luminescent organometallic platinum-, palladium- and nickel complexes (DFG SPP 2102 – light controlled reactivity of metal complexes)
  • Cytotoxic organometallic Pt- and Pd complexes
  • Complexes with N-rich ligands
  • New thiosemicarbazone ligands and their transition metal complexes
  • New organic-inorganic hybrid perovskites
  • Hybrid materials of semiconductor nanoparticles and complexes
  • Coordination chemistry of low valent U and other actinides
