Abstract
Chemically inert, mechanically tough, cationic metallo-polyelectrolytes designed as durable anion-exchange membranes (AEMs) via ring-opening metathesis polymerization (ROMP) of cobaltocenium-containing cyclooctene with triazole as the only linker group, followed by backbone hydrogenation to provide a new class of AEMs with a polyethylene-like framework and alkaline-stable cobaltocenium cation for ion transport, which exhibit excellent thermal, chemical and mechanical stability, as well as high ion conductivity.
