Abstract:

Symmetrically and unsymmetrically substituted polydi-2-thienyl-2,5- dialkoxy-p-phenylenes have been prepared and studied. X-ray studies have shown that the unsymmetrically substituted polymer is completely amorphous while the symmetric polymer exhibits a high level of crystallinity. The dihexadecyloxy derivative has been observed to be birefringent and, after NOPF6 doping, a film of this polymer shows a conductivity of 3 OHM per centimeter. A water soluble benzylsulfonate derivative of Kevlar has been prepared and a polypyrrole film formed with this as the electrolyte shows a conductivity of ca. 10 OHM per centimeter. Polypyrrolenaphthalene sulfonate thin films can be used to detect ppb quantities of hydrazine in the presence of ammonia. A new technique which combines cyclic voltammetry with Raman scattering has been developed.
