A diamine monomer was synthesized from 3,3′-dihydroxybenzidine in four steps, and its polymerization was performed with 1,4,5,8-naphthalenetetracarboxylic dianhydride in the presence of triethylamine and benzoic acid in m-cresol. A flexible, ductile, and self-standing membrane was obtained via casting from an m-cresol solution. Good thermal, hydrolytic, and oxidative stability was confirmed. The ionomer membrane showed very high proton conductivity of 1.0 S cm−1 at 120 °C and 100% relative humidity, which is higher than that of a Nafion membrane.
