This paper describes the preparation and characterization of a novel ion‐conducting polymeric material (2). The backbone consists of alternating alkenylidene and sulfanylidene units with adjacent hydroxy groups. Fitting of the experimental impedance data of 2 in a Bode plot reveals a conductivity of 6.6 × 10−2 S · cm−1 and a capacitance of 2.2 × 10−5 F at room temperature. The deuterated derivative of 2 shows significantly lower conductivity, suggesting that the conductivity of 2 can be attributed to proton migration.
