Synthesis, phase structure and ion conductivity of poly(p-phenylene) functionalized with lithium trifluoromethanesulfonimide and tetra(ethylene oxide) side chains
Rigid-rod polymers tethered with delocalized anions and flexible ion conductive side chains present a synthetic pathway towards thin, single-ion conducting electrolyte membranes with low bulk resistance and high mechanical stability. In the present work we have synthesized poly(p-phenylene) (PpP) copolymers carrying lithium trifluoromethanesulfonimide groups and tetra(ethylene oxide) side chains t
