Design and manipulation of functional molecular nanosystems at interfaces

Abstract:
The control and organization of molecular species at interfaces is key to advance molecular science, nanochemistry and the development of novel materials. We explore the pertaining bonding, assembly and dynamic behaviour at well-defined homogenous surfaces, textured templates and sp2-sheet layers. The developed bottom-up fabrication protocols employ biological and de novo synthesized building blocks, exploiting error-corrective bonding schemes as well as covalent chemistry. Our approach provides a rationale for the interfacial control of single molecular units and the design of nanoarchitectures with remarkable structural features, intricate dynamics and tailored properties.

Biography:
After studying physics at Munich’s Ludwig Maximilian University (LMU), Prof. Barth received his doctorate in physical chemistry under Prof. G. Ertl at the Fritz Haber Institute of the Max Planck Society in Berlin (1992). Following that, he became an IBM Postdoctoral Fellow at the IBM Almaden Research Center in San Jose, USA. He spent over a decade continuing his work at the École Polytechnique Fédérale de Lausanne, Switzerland. Prior to his appointment as a full professor at Technische Universität München (TUM) in 2006, he researched and taught at the Canada Research Chair at the University of British Columbia in Vancouver. He is currently the Dean of Physics Department at TUM and the Chair in Molecular Nanoscience and Surface Chemical Physics.
