Research Overview

Organic synthesis enables the precise generation of functional molecular building blocks and constitutes the basis of chemical approaches that our group is developing to address various aspects of materials science. We are convinced that the design of custom-tailored molecular nano-objects and their integration into functional nanosized structures will be key to the future bottom-up fabrication of miniaturized devices and the creation of new responsive “smart” materials. Our work is primarily focused on the design and synthesis of (macro)molecules with defined geometrical and electronic structure to target a desired property and function of the resulting materials. Complementing our synthetic efforts, we are investigating structure-property relationships as well as fundamental molecular processes on both the single molecule and the ensemble levels in solution and in the bulk, yet with particular focus on interfaces.

Currently, we are following several lines of research and our main efforts are directed towards:
  • Remote-controlling function: Developing photoresponsive (switchable and triggerable) reactive and catalytically active systems as well as charge and energy transporting systems for spatio-temporally resolved chemistry and signal amplification.
  • Light-powered processes: Designing various light-driven macro- and supramolecular systems that exploit cooperative phenomena to directly convert (sun) light into materials response with regard to mechanical and (self)healing properties, among others.
  • Surface-confined chemistry: Controlling conformation, self-assembly, and chemical reactivity (switching and covalent bond formation) of individual molecules and their assemblies on solid substrates for nanoconstruction, molecular-scale electronics, and sensing.
