Abstract
An ion conducting polymer comprising a modified poly(phenylene oxide) is described. In an exemplary modified polymer, a portion of the monomeric units are attached to a sulfonate-substituted arylamino moiety, such as a monovalent derivative of phenoxy aniline trisulfonate (BOATS), to form a monomeric unit with a charged side chain. Ion conducting polymers can also be prepared with polyether-containing side chains. The ion conducting polymer can be used to prepare ion exchange membranes which can be used in a variety of applications, such as in non-aqueous redox flow batteries and related energy storage systems.
