- W1990477411 abstract "An electrochemical study of fused pyrroles, i.e., 1,4-dihydropyrrolo-[3,2-b]pyrrole (PP), 3,6-di-t-butyl-1,4-dihydropyrrolo[3,2-b]pyrrole (BPP) and dimethyl 1,4-dihydro-3,6-di-t-butyl-pyrrolo[3,2-b]pyrrole-1,4-dicarboxylate (BMPP), was carried out. PP could be polymerized electrochemically on InSn oxide conducting glass (ITO), basal-plane pyrolytic graphite, Pt or Au electrodes, while BPP and BMPP could not be electropolymerized. The polymeric film (PPP) prepared from PP was electroactive in both acetonitrile and aqueous solutions. The morphology of PPP films was found to depend on the supporting electrolytes used. The conductivity of the film was 5 × 10−5 S cm−1 just after its preparation and decreased gradually when exposed to air. The film thickness (φ) was linearly related to the amount (Q) of charge passed in the polymerization, with Q in the range 5 to 150 mC cm−2 (slope of the φ versusQ plot: 4 μm C−1 cm2). The PPP film was found to undergo degradation via electrochemical oxidation at the electrode and chemical oxidation by oxygen in air. Furthermore, the physical and electrochemical properties are compared with those of polypyrroles, polymers of other fused heterocycles, etc." @default.
