Switchable molecularly functionalized surfaces

The research group “Switchable molecularly functionalized surfaces” develops innovative hybrid surfaces consisting of redox- and spin-active molecular compounds immobilized as single molecules or thin films on technical material systems. These next-generation surfaces should provide new functions for data storage and processing (integration of semiconductor technology with molecular chemistry and physics) or can be used as chemosensors in diagnostics. The research focuses on the stability, sensory efficiency, and electrical performance of molecular logic states of metal complexes on conducting and semiconducting surfaces as bottom electrodes and their manipulation by the tip of a scanning probe microscope as the top electrode. The goal is to introduce stimuli-responsive, functional materials into industrial applications in the areas of digital transformation, green-IT, as well as therapy and diagnostics in medicine. This will be achieved through a deep scientific understanding of hybrid surfaces.
