High-performing phenanthrene-containing poly(arylene piperidinium)s for anion exchange membranes
Incorporating fused benzene rings in backbones of anion conducting polymers may improve the properties of anion exchange membranes (AEMs). Here, we haveprepared and studied ether-free AEMs based on poly(arylene piperidinium)s containing up to 50% phenanthrene units. A series of terpolymers were prepared in superacid-mediated polyhydroxyalkylations of phenanthrene, p-terphenyl and N-methylpiperidon
