Water-soluble conducting polymers having a chemical structure represented by, for example, the formula (I)n n wherein R¹ and R² independently represent H, a C₁ to C₂₀ alkyl or alkoxy group, amino group, trihalomethyl group or phenyl group, X represents S, O, Se, Te or NR₃, R₃ represents H, a C₁ to C₆ alkyl group or an aryl group, M represents a cation such as H⁺, an alkali metal ion or quaternary ammonium, and m is 0.2 to 2 and a method for the production thereof by the reaction of a sulfonating agent on a derivative of, for example, isothianaphthene or isobenzofuran. |
