Research Profile

Our research aims the design of novel liquid crystalline (LC) materials controlling the self-assembly of functional building blocks on a nanometer scale. The fluid properties facilitate the orientation of these nanostructures in self-healing thin solid films. We focus on LC molecules with non-conventional topology such as star, bent, board shape or Janus compounds. The structures are fine-tuned by the generation of free space, in which guests can be incorporated. Nanosegregation of incompatible building blocks and space-filling conduct the positioning of molecular units and produce complex functional LC materials. Detailed knowledge of these self-assemble processes is achieved via comprehensive studies by X-ray scattering techniques, modelling and photophysical investigations, which leads subsequently to the development of stimuli-responsive materials.
