Date : 2013. 3. 14, 4:30 PM Place : Mogam Hall, Bldg.500 - Abstract- This seminar will describe our group"s recent efforts on using a range of stimuli, including mechanical force, light, and redox processes, to finely control various chemical reactions or to access transformations that are altogether new. The design and development of specially designed catalysts that contain photo and/or redox responsive N-heterocyclic carbene ligands as well as novel polymeric materials are tightly coupled with the aforementioned methods, and will be presented. Likewise, extensive spectroscopic analyses and control experiments to probe underlying mechanisms will be discussed. The presentation will conclude with some perspectives on using various stimuli to control other types of small molecule and macromolecular chemistry.
