Projektbeschreibung der*des Nominierenden
| Professor Wang is internationally renowned for his pioneering work on the photoelectron spectroscopy of mass selected molecular anions under controlled, ultrahigh-vacuum conditions. As a consequence of sustained spectrometer technology and ion source development, the Wang group has continued to have the most sensitive and highly resolved instruments in the world with which to study such species. These instruments have been applied to many systems of broad chemical interest and the resulting photoelectron spectra have typically allowed fundamental insights into the corresponding bonding properties. He was one of the first people to systematically interpret his photoelectron measurements on the basis of high level quantum chemical calculations leading in many cases to important insights concerning novel bonding behaviour. Examples include work on planar fourfold coordinated carbon, studies of aromatic-like bonding in small metal doped aluminium cluster ions, probes of cluster size-dependent topology switching in boron aggregates and the structure determination of gold clusters. Apart from his work on cluster-based systems, Professor Wang is also well known for his contributions to the systematics of molecular multianions. Wang's group was the first to demonstrate that specific, multiply negatively charged molecular anions (accessible to mass spectrometric probes) were electronically metastable. Furthermore, he was able to identify the corresponding decay channels - notably tunneling electron autodetachment processes and to quantify the associated Coulombic barriers. Recent work on the 'textbook' multianion SO42- and the energetics of its water salvation, is a further case in point. Professor Wang will divide his time in Germany mainly among research groups in Karlsruhe and Berlin. In Karlsruhe he intends to collaborate with the group of Professor M. Kappes on structural probes of doped boron clusters as well as on the femtosecond time resolved photoelectron spectroscopy of organometallic multianions. In Berlin he plans to work together with Profs. Schwarz, Sauer and Wöste on the structure and catalytically-relevant chemical properties of metal oxide clusters. |
