		Electrically Conductive Polymers Primary interests include developing new conductive polymer compositions and developing quantitative group additivity principles (structure/property relationships) for constructing conjugating conductive polymers with predictable optical, electrical, and electrochemical properties. Classes of polymers being studied comprise polyaromatics and polyheteroaromatics, as well as poly (arylene vinylenes) and their non-conjugated precursors. New synthetic methods for the development of high molecular weight polymers are being explored. Applications being developed for conjugated polymers include electroluminescent displays, lightweight superconductors, and corrosion preventive coatings for steel. Mechanistic Organic and Polymer Chemistry Studies focus on the preparation and reactivity of various quinodimethane intermediates and polymerization to high molecular weight polymers. Further, we are investigating novel, non-redox methods for doping conjugated polymers to highly conductive compositions. Materials Science of Conjugated Polymers Studies here are concerned with the macroscopic solid-state properties of highly conjugated polymers. Our efforts are directed at developing an understanding of how polymer preparation, processing and post-processing fabrication can influence the ultimate conductive and mechanical properties of conjugated polymers and blends.
