A method of making an ion conducting membrane includes a step of reacting a compound having formula 1 with a polymer having polymer segment 2:
to form a copolymer having polymer segment 2 and polymer segment 3:
and
The copolymer having polymer segment 2 and polymer segment 3 are then formed into an ion conducting membrane, wherein Z is a C
