  • Publication number: 20120208978
    Abstract: An electrically conductive polymer obtained by oxidative polymerization of a heterocycle-containing aromatic compound as a monomer, wherein the heterocycle-containing aromatic compound is represented by the formula: A-B. In the above formula, A represents a substituted or unsubstituted thiophene ring group, or a substituted or unsubstituted pyrrole ring group; B represents a substituted or unsubstituted hydrocarbon aromatic ring group, a substituted or unsubstituted thiophene ring group, or a substituted or unsubstituted pyrrole ring group; the ring represented by A and the ring represented by B are directly linked; however, A and B represent structures that are different from each other. The compound can be produced by a coupling reaction using a hypervalent iodine reactant.
