Electronic and Ionic Transport in Polymers

Abstract

By employing Sodium Hydroxide dedoping high/low conductivity interfaces have been prepared. Optoelectrochemical properties of several thiophene-phenylene-thiophene polymers have been studied. Blends of poly(3- decylthiophene) with polyethylene or poly(ethylene terephthalate) have been prepared. The ion binding properties of copolymers of pyrrole and 3-(1-pyrrolyl) propanesulfonate have been studied for the first time using Ru(NH3)6(3+) and Ru(bpy)3(2+) (bpy=2,2'-bipyridyl) as the ion probes. Molecular orbital calculations have been used to estimate the equilibrium ground state geometries of alternating copolymers of substituted phenylenes and bithiophenes. Calculated spin populations suggest possible Alpha-Beta and/or Beta-Beta linkages in addition to Alpha-Alpha linkages. Calculated band gaps are between those of poly(p-phenylene) and polythiophene.
