In honor of Albert Weller (1922-1996), the GDCh Division of Photochemistry , together with the German Bunsen Society for Physical Chemistry, usually awards the Albert-Weller Award for an outstanding dissertation in the field of photochemistry / spectroscopy every two years . The award is intended for young academics up to a maximum of two years after their doctorate and is combined with an award certificate and prize money of 1,000 euros. Usually, the handover takes place on the occasion of the annual meeting of the Division of Photochemistry , which takes place in even years, and the awardee winner is invited to present the award-winning work in a scientific lecture . A panel of experts made up of members from both societies will decide on the award of the prize. The prize can be shared.
The Division of Photochemistry of the German Chemical Society and the German Bunsen Society for Physical Chemistry award the Albert-Weller Award 2020, donated by ATTO-TEC GmbH, to Dr. Michael Peter Kathan and Dr. Yusen Luo.
The award is given to Dr. Kathan awarded in recognition of his outstanding dissertation with the title: "Photoswitching Reactivity - From Remote-Controlled to Light-Driven Chemical Systems". The award winner's impressive work deals with the fundamental question of the photochemical control of thermal equilibria Developed creative approaches to optically control and drive condensation-hydrolysis equilibria with the help of photoswitches. Through the creative coupling of photo-induced 6? electrocyclization and thermal keto-enol tautomerism, he was able to remotely control living polymerization processes on the one hand and dynamically covalent imine- Bonds contrary to their equilibrium position, ie quasi uphill, tie or break. His work has significant application potential for self-healing materials, for example in sensors and for solar recycling of polymers. The dissertation was in the working group of Prof. Dr. S tefan Hecht at the Humboldt University in Berlin.
The prize is awarded to Dr. Luo to recognize her outstanding doctoral thesis, entitled: ?Photoinduced Electron Transfer Dynamics in Ruthenium (II) Bis (terpyridine) Based Molecular Dyads and Triads?. Dr. Luo studied the photoinduced electron-transfer dynamics in covalently linked molecular dyads and triads as model systems for molecular photoredox catalysts. Using model systems comprising a Ru-terpyridin-based photosensitizer, a fullerene acceptor and a phenothiazine donor, Dr. Luo could obtain novel insights into the mechanisms of photodriven electron transfer. Resorting on temperature-dependent ultrafast time-resolved transient absorption spectroscopy, Dr. Luo experimentally demonstrated novel effects, eg investigating the impact of a formally spectator ligand on the electronic coupling between photosensitizer and electron donor. Such "remote control" of electron transfer has been speculated about but has never been demonstrated experimentally before.
