Welcome to the Science of Sweet Salts!

Our research interests

  • development and fundamental understanding of new carbohydrate-based ionic liquids and salts (CHILS)
  • optimization of highly cost- and yield-efficient CHILS syntheses
  • investigating carbohydrate-based ionic liquids and salts as green alternatives to common ionic liquids by developing biocompatible and biodegradible CHILS
  • application of CHILS in  bio- and organocatalysis, in organometallic complexes, in polymer chemistry and more
