| description | A series of poly(<i>meta/para</i>-terphenylene-methyl piperidinium)-based anion exchange membranes devoid of benzylic sites or aryl ether bonds, that are vulnerable to degradation by hydroxide ions, are synthesized and investigated for their application as novel anion exchange membranes. The copolymers are composed of both linear <i>para</i>-terphenyl units and kink-structured <i>meta</i>-terphenyl units. The <i>meta</i>-connectivity in terphenyl units permits the polymer backbones to fold back, maximizing the interactions among the hydrocarbon polymer chains and enhancing the peripheral formation of ion aggregates, due to the free volume generated by the kink structure. The effects of the copolymer composition between <i>para</i>-terphenyl and <i>meta</i>-terphenyl on the morphology and the electrochemical and physicochemical properties of the corresponding polymer membranes are investigated. |
