TLC2 seminar focuses on molecular electronic devices
The Texas Learning and Computation Center hosted its Research Seminar Series, held on the second Friday of each month for the school year 2007-2008. Dr. Eric Bittner, Dept. of Chemistry, discussed the research he conducted as a recipient of TLC2 Innovation Funding into quantum dynamics in molecular electronic devices.
Abstract
Electronic materials made of plastic organic polymers may seem the stuff of science fiction; however, many polymers are semiconducting and one can use both their chemical and physical properties to make devices ranging from flexible displays to plastic logic circuits. Dr. Bittner’s work in this area has focused upon how vibronic interactions tune and couple the relevant intra- and inter-molecular electronic states that determine many of the device characteristics of these systems.
In his talk Dr. Bittner focues on one particular class of these materials, namely bulk heterjunctions, that are used in both light-emission and light-harvesting applications. Using state-of-the-art quantum chemical and quantum dynamical methods his research shows that this is due to a phonon-coupled ultrafast recycling of charge-separated exciplex states pinned to at the interface to form secondary excitons. Discussions also included the possible role of triplets, the role of stacking morphology, and dark exciplexes.
About Dr. Bittner
Dr. Bittner is an Associate Professor in the Chemistry Department. He was recently named a Guggenheim Fellow and spent last term at the University of Cambridge as a Visiting Fellow of St. John's College. He received his PhD in Chemistry from the University of Chicago in 1988.
