Abstract
  Photovoltaics and solid state lighting are examples of technologies that are enablers for a new sustainable energy economy, since these technologies would allow us to use a renewable energy source, and to use energy sources we already have more efficiently. The successful development of alternate low cost technology for current lighting devices will have a significant impact on the U. S. economy and national security. White organic light emitting diodes (OLEDs) with potentially high power efficiency are considered as strong candidate for the next generation of illumination devices. Moreover, the use of environmentally benign organic materials in white OLEDs and their potentially low fabrication cost makes them an attractive technological prospect.  In this presentation, we will discuss our continuing efforts on the design, synthesis and characterization of stable and efficient platinum and palladium complexes for displays and lighting applications.  The photo-physics, electrochemistry, electroluminescent properties and operational stability of these novel platinum complexes, including fluorine-free Pt-based deep blue emitters, will be discussed.  The rational molecular design enables us to develop cyclometalated Pt complexes with both photon-to-photon (in thin film) and electron-to-photon (in device settings) conversion efficiency close to 100% for OLED applications as well as record device operational time of over millions of hours.

Brief Bio:
  Dr. Jian Li received his B.Sc. degree in Chemistry from Fudan University in 1997, and his M.Sc. degree in Electrical Engineering and Ph.D. degree in Chemistry from the University of Southern California during 1999-2005. In 2006, he was appointed as an assistant professor in the School of Materials at the Arizona State University and received his full-tenured promotion in 2018. His research interests include materials design and synthesis for organic semiconductor materials, investigating charge-transporting, energy transfer, and radiative or non-radiative decay process inside of the organic solids.  In the past 10 years, he has worked with his colleagues to raise over $50 million external funds from DOD, DOE, NSF and private industries for the university including $8 million for his own research group. Dr. Li has published over 60 research papers with total citations of over 6000 (google scholar) and has received 50 issued US patents and filed over 60 pending patent applications.  He was the recipient of NSF CAREER Award and has been a symposium organizer or co-organizer for multiple MRS and OSA national meetings.
