Topic: Emerging Guidelines for the Design of Organic Semiconductors
Speaker: Prof. Guillermo C. Bazan (University of California, Santa Barbara)
Venue: Room 502, Building No.1, Wushan Campus
Time: Friday, Mar 9, 2018, 15:00
This presentation will initially focus on the impact of molecular structure on the organizational and functional properties of organic semiconductors. Special emphasis will be placed on understanding organizational principles under kinetically confined conditions as a result of non-covalent interactions; for instance, the diversity of conformational isomers, presence of solvent additives, and molecular reorganizations that may favor amorphous or crystalline phases.  Examples will be provided that illustrate translation of morphological control into more efficient optoelectronic devices, including organic solar cells.
The second part of the seminar will center on the properties of narrow bandgap conjugated polyelectrolytes, and in particular how the electrostatic field of the adjacent charged groups can be used to modulate doping preferences of the electronically delocalized backbone.  New emerging applications for these materials will be demonstrated, including the ability to dope other semiconductors, including carbon nanotubes and graphene, and to serve as relays for electron transport from living anaerobic microorganisms.
Professor Bazan obtained his B.Sc. (Honors) from the University of Ottawa and his Ph.D. from the Massachusetts Institute of Technology under the advisement of Professor Richard R. Schrock. After working at the California Institute of Technology as a postdoctoral fellow with advisor Professor John E. Bercaw, he started his academic career at the University of Rochester in 1992. In 1998, Gui became a Professor of Chemistry at the University of California, Santa Barbara. A year later he joined the faculty of the Department of Materials (Engineering) and in June 2000, he became the Director of the Center for Polymers and Organic Solids.
Professor Bazan has over 545 publications, an h-index of 105, and his work has been recognized by the Arthur C. Cope Scholar Award of the American Chemical Society (2007) and the Bessel Award of the Humboldt Foundation. He is a fellow of the American Association for the Advancement of Science.
