Subject: 13.03.06 Webinar: "The Electronic Couplings in Electron Transfer and Excitation Energy Transfer"
Title: "The Electronic Couplings in Electron Transfer and Excitation Energy Transfer" Presenter: Prof. Chao-Ping (Cherri) Hsu, Academia Sinica When: Wed, Mar 6, 2013, 8:00 PM - 9:00 PM EST Duration: 1 hour Registration: https://attendee.gotowebinar.com/register/8691085612110559744 Summary: In recent years, research focusing on advanced materials and on molecular level of understanding in biological systems has attracted a lot of attention. One class of important reactions in this areas is the electron transfer (ET) process. Understanding of the corresponding electronic coupling becomes important since the coupling is an important parameter in the ET rate expression in the weak-coupling limit. Theoretical determination of ET coupling does not only provide a route to deeply understand the ET process, but also offers crucial hints to the designing of new functional molecules. Electronic coupling is an important factor in the ET rate constant in the weak-coupling limit. We have developed several new methods for calculating ET coupling and have applied them to functional organic molecules. In addition, we are also interested in excitation energy transfer (EET), where excitation energy between two molecules/fragments is exchanged. The singlet-singlet EET is widely known as Forster's dipole-dipole interaction. We have recently studied the triplet-triplet EET, which is similar to the Dexter's exchange coupling. For the first time, ab initio triplet-triplet exchange coupling can be calculated and reported. Our results offer the basis to understanding previous experimental observation without additional mechanisms. About the Presenter: Cherri received her Ph.D. in Chemistry in 1998 from the California Institute of Technology. She was a Miller Research Fellow at the University of California at Berkeley from 1998 to 2001. She joined the Institute of Chemistry, Academia Sinica, in 2002, where she is now an associate research fellow (http://www.chem.sinica.edu.tw/faculty/index_en.php?piName=cherri). Her main research interest in computational chemistry has been in the characterization of electronic coupling for charge and energy transports. Cherri has been recognized by many awards, such as the Wu Ta-You Memorial Award from National Science Council of Taiwan (2008 ); Junior Researcher Award, Academia Sinica (2009); Pople Medal, Asia-Pacific Association of Theoretical & Computational Chemists (2010); Outstanding Young Scholar Award from Shui-Mu Foundation of Chemistry (2011).NOTE THAT E-MAIL ADDRESSES HAVE BEEN MODIFIED!!!
