Functionalized Imidazolium Ether-Free Polymer Backbones with Ion Transport Channels and Catalytic Activity.

ABSTRACT: Novel ether-free bond polymer backbones were synthesized through polycondensation in a superacid medium by using p-terphenyl and 4-(1H-imidazol-1-yl)benzaldehyde. The presence of imidazolium groups enabled further modifications through a highly efficient nucleophilic substitution reaction introducing cationic sites essential for anionic transport. Characterization by NMR and FTIR analyses confirmed the structures and the complete functionalization of the base polymer. Critical properties for potential anion exchange membrane applications, including water uptake, ion exchange capacity, ion conductivity, morphology, and thermal and mechanical stabilities were investigated. Results indicated that these polymers form stable ion transport channels, with the formation of distinctiv
