Presenter: Prof. Guillermo C. Bazan (University of California, Santa Barbara)
Topic: Emerging Guidelines for the Design of Organic Semiconductors
Time: 10:00 AM, Feb. 2nd (Friday)
Location: 909-B
Abstract
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.
