Abstract
A series of derivatized bis(pyrrol-2-yl) arylenes, specifically 1,4-bis(pyrrol-2-yl)benzene (1e, BPB), 1,4-bis(pyrrol-2-yl)-2,5-dimethoxybenzene (2e, BPB(OCH3)2), 1,4-bis(pyrrol-2-yl)-2,5-diethoxybenzene (3e, BPB(OC2H5)2), 1,4-bis(pyrrol-2-yl)-2,5-didodecyloxybenzene (4e, BPB(OC12H25)2), 2,6-bis(pyrrol-2-yl)naphthalene (5e, BPN), and 4,4‘-bis(pyrrol-2-yl)biphenyl (6e, BPBP) have been synthesized. Cyclic voltammetry shows these monomers to oxidize at relatively low potentials to form cation radicals. The lowest peak monomer oxidation potential of +0.15 V vs Ag/Ag+ is observed for 2e, lower than that reported for any other pyrrole-based monomer. Electrochemical polymerization from a 0.01 M monomer, 0.1 M tetrabutylammonium perchlorate (TBAP), and acetonitrile solution was carried out using multiple scanning cyclic voltammetry to yield polymers having E1/2 values ranging from −0.1 to +0.1 V. These low oxidation potentials cause the polymers to be quite stable in the electrically conducting form. The electron...
