The Award: The Richard C. Tolman Medal is awarded each year by the Southern California Section of the American Chemical Society in recognition of outstanding contributions to chemistry in Southern California. The Tolman Medal recognizes broad accomplishments in chemistry rather than a single fundamental discovery. These contributions may be of several kinds, including seminal research of widely regarded influence, achievements of broad impact in chemical technology, significant contributions to chemical education, and outstanding leadership in science on a national level. To be eligible for the Medal, the recipient must have accomplished a major portion of his or her work while a resident of Southern California.
Abstract: We have developed a great deal of chemistry around phosphorescent iridium and platinum complexes for monochromatic and white OLEDs. These materials give LEDs with efficiencies close to 100%. The reason that these Ir and Pt complexes perform so much better than pure organic analogs is that the electroluminescent process generates a mixture of singlet and triplet excited states. The strong spin orbit coupling of third row transition metals efficiently mixes singlet and triplet states, allowing us to collect all of the electrically generated excitations. In this talk, I will start with the mechanism of electroluminescence and then move on to our work in studying a wide range of iridium and platinum organometallic complexes, which emit with near unit efficiency from the UV to the nearinfrared. We have prepared high efficiency OLEDs with the visible and NIR emitting materials. I will also discuss our efforts to generate broadband (white) emitting OLEDs. Time permitting, I will discuss our recent results with Copper based phosphors for electroluminescence.
2013 Richard C. Tolman Award Recipient
The Southern California Section of the American Chemical Society is pleased to announce the 2013 Recipient of the Richard C. Tolman Award, Mark E. Thompson of USC.
Dr. Mark E. Thompson (Ph.D., California Institute of Technology) is Professor of Chemistry at the University of Southern California. Dr. Thompson received his B.S. degree in Chemistry in 1980 (U.C. Berkeley) and his Ph.D. in chemistry in 1985 (California Institute of Technology). He spent two years as a S.E.R.C. fellow in the Inorganic Chemistry laboratory at Oxford University. Prof. Thompson took a position in the Chemistry Department at Princeton University in 1987, as an Assistant Professor. In 1995, Prof. Thompson moved his research team to the University of Southern California, where he is currently a Professor of Chemistry. His research program involves the study of new materials and devices for electroluminescence, solar energy conversion, chemical/biological sensing and catalysis. Prof. Thompson is the author of approximately 300 papers in refereed professional journals and holds more than 130 patents primarily in the areas of molecular and polymeric materials for optoelectronic applications, organic thin film devices, and heterogeneous catalysis.
