Electronic and Ionic Transport in Polymers
Abstract
High molecular weight poly 3-alkylthiophenes have been prepared and cast into films and made into fibers. Molecular composites of polypyrrole with polyelectrolytes polystyrene sulfonate and poly(phenyleneterephthalamide propanesulfonate) have been prepared and characterized by electrochemical microgravimetry. By derivatizing doped polypyrrole membranes with 2,6-di-p-toly- 4-phenylpyrylium reagent, dopant ion fluxes during electrochemical reduction down to parts per billion could be measured. Extensive PRDDO conformational EH band structure calculations have been done on the aromatic and quinoid forms of poly(isothianaphthene), poly(thieno3,4-Bnaphthalene-9,11-diyl) and related systems. Very high molecular weight, low polydispersity, polymers such as poly(octamethylene sulfide) have been made by a novel polythioetherification using phase transfer catalysis and tetrahydrothiophene also as a catalyst.
