Abstract

A novel aromatic polymer electrolyte with pendant sulfodecyloxy groups was synthesized. The monomer 4, bis[2-(10′-sulfodecyloxy)-5-chlorophenyl] sulfone, was synthesized from bis(2-hydroxy-5-chlorophenyl)sulfide via bromoalkylation, oxidation, and sulfonation, and then polymerized via Ni-catalyzed C-C coupling polymerization to afford the title polymer electrolyte 6. The polymer 6 was isolated as a brown powder with molecular weight of M̄_w = 12000. The high decomposition temperature of 6 (200 °C) was confirmed by TG/DTA-MS measurement. Proton conductivity of 6 was measured using porous polyimide membrane as a supporting substrate. The pore-filled membrane showed 1 × 10^-5 S · cm^-1 of the proton conductivity at 80°C and 90% RH.
