Highly Regioregular Polythiophenes for Magneto-Optical Applications

Abstract

The synthetic research efforts focused on three main topics: (1) a profound, detailed study of the polymerization of regioregular, head-to-tail coupled poly(alkoxythiophene)s (HTP3AOTs), (2) the development of processable, high-molecular weight polydithienopyrroles (PDTPs), (3) the construction of alternating copolymers of cyclopentadithiophene and thiophenes (P(CPDTaltT)), and (4) the development of soluble, highly ordered polythienothiophenes (PTTs). All these polymers are highly conjugated, thiophene-based polymers, with large variation in their bandgaps. In view of the important role of regioregularity in the Faraday rotation observed in thin films of polythiophenes an important part of the research effort was focused on the development of synthetic methodologies and a search of new polymers. Additionally the physico-chemical properties of several polythiophenes were investigated, with some remarkable results. Also the magnetic properties of several polythiophenes were investigated, as well as new polythiophenes synthesized. Final work involved in search for new synthetic pathways for new polythiophenes and the initiation of computer calculations/simulations to identify polymer conformations active in magnetic properties of several polythiophenes. Initial attempts were made to develop a new model based upon previous results to describe magnetic effects in organic media.
