Abstract
A quinone-containing poly(arylene) includes repeating units of formula (I), (II), (III), (IV), (V), or (VI) as defined herein. The quinone-containing poly(arylene) can be useful in composites, electrode assemblies, electrochemical cells, gas separation systems, energy storage devices, and electrochromic devices.
