We report on poly(arylene-imidazoliums), which were synthesized by microwave polycondensation of dialdehyde with bisbenzil and quantitatively functionalized by alkylation. This cationic polyelectrolyte is sterically protected around the C2-position a

The application of highly charged anion exchange membranes is often limited by strong water sorption leading to excessive swelling and eventual dissolution, especially at elevated temperatures. The cross-linking of polymers has been shown to be an ex
