Cobaltocenium-containing poly(carbazole)s towards alkaline-stable anion exchange membranes via post-polymerization modification

Abstract

Robust alkali-resistant cobaltocenium-containing poly(carbazole)s are prepared via the combination of superacid-catalyzed polyhydroxyalkylation and CuAAC-based post-polymerization modification. The prepared cobaltocenium-containing AEMs show a hydroxide conductivity of up to 127.2 mS cm⁻¹ at 80 °C and a conductivity retention of more than 95.0% after soaking in 1 M NaOH for 2500 h.
