    • Mario Leclerc was awarded a Ph.D. in chemistry from Laval University, Quebec City, Canada, in 1987. After a short stay at INRS-Energie in Montreal, he joined the Max Planck Institute for Polymer Research, Mainz, Germany, as a post-doctoral fellow. He returned to Canada in 1989 and accepted the position of assistant professor at the Department of Chemistry, University of Montreal, where he became associate professor in 1994. His main research interests are in the synthesis, characterization, and applications of electroactive and photoactive polymers. His current research activities include the development of novel polythiophenes and polyfluorenes for applications in electronics and photonics.

Abstract

Control of the electrical and optical properties of different polythiophene derivatives can be achieved, to some extent, by adjusting the nature of their substituents. The effects of flexible side chains (increase in solubility, modification of the stability of the conducting state, induction of thermo-, iono-, photo-, or biochromism) such as alkyl or alkoxy moieties are reviewed and the promising self-doped polythiophenes (see Figure) discussed.
