Electronic and Ionic Transport in Polymers
Abstract
We have prepared and studied a variety of electroactive polymers including self-doped conducting polypyrroles, high molecular weight poly(3- alkylthiophenes), new polymers containing both various aryl groups along the main chain and solublizing substituents, electroactive polymers containing main chain transition metal complexes, fluoropolymers for high permittivity materials, liquid crystalline polymers and polymers containing PN linkages in the main chain. We have also prepared films and/or fibers of these materials both pure and as blends and molecular composites (using polyelectrolytes). We have used spectroscopy, electrochemistry and microgravimetry to study ion transport and redox switching in these systems and have developed in situ techniques to monitor and quantify this ion transport. We have used theoretical calculations (PRDDO and ab initio) to study HOMOLUMO gaps, spin densities, structures and conformations in monomers and oligomers and have used these methods and Extended Huekel calculations to estimate band gaps and to help understand substituent effects in these polymers. Keywords: Electroactive polymers; Polythiophenes; Polypyrroles; Ion transport; Molecular composites; Molecular orbital calculations; Organometallic polymers; Liquid crystalline polymers.
