Molecular Nanoscience at Interfaces
Our research aims at the fundamental understanding of surface chemical processes and interface phenomena, encompassing the exploration of model systems for heterogenous catalysis and the design of functional nanoarchitectures in reduced dimensions. We explore individual nano-objects, highly organized supramolecular systems and on-surface synthesis protocols. Utilizing scanning probe microscopy tools we examine the interior of complex molecular species and develop self-assembly protocols for nanotextured surfaces and low-dimensional metal-organic coordination systems. With advanced spectroscopy techniques we study charge transfer, electronic reconfiguration processes and chemical conversions.
