Tuning the Performance of Poly(quaterphenyl piperidinium) Anion‐Exchange Membranes by Monomer Configuration

open access: yesAdvanced Energy Materials, EarlyView.
Ether‐free poly(quaterphenyl piperidinium) ionomers are prepared by superacid‐mediated polyhydroxyalkylations and explored as hydroxide conducting membranes. The para‐meta configuration of the quaterphenyl monomer greatly influences polymer backbone flexibility.
