Specific themes and goals

We synthesize and develop:

  • Fluorinating and polyfluoroalkylating as well as fluorinated building blocks to modify biological and pharmacological active compounds
  • Modern fluorinated liquid crystal molecules for LCD-displays
  • High-performance lithium-ion battery electrolyte components
  • Novel bisphosphonates, active agents against osteoporosis and bone cancer
  • New perfluorinated monomers for copolymerization
Highlights and impact
  • We synthesized and investigated fluorine- and phosphorus-containing compounds for their application in material science and medicinal chemistry.
  • We design and developed lithium battery electrolytes.
  • We synthesized and used fluorinated monomers in high-performance polymers.
  • We used new small molecules containing phosphorus and fluorine as bioactive compounds.
  • The group contributed to two books, and filed five patents.
Group composition & projects/funding

Between 2019 and 2022, the group consisted of six postdoctoral research associates and two PhD candidates working on basic research projects concerning organofluorine chemistry. They were supported by the German Research Foundation (DFG) jointly with the National Natural Science Foundation of China (NSFC) and the Czech Science Foundation (GACR). Further projects deal with lithium battery component development supported by the Federal Ministry of Economy and Energy (BMWi), together with the Münster Electrochemical Energy Technology (MEET) research center and companies like Bosch and BASF. In industrially oriented projects, we designed and developed fluorinated high-performance materials.
