The present disclosure concerns the synthesis and investigation of a series of bis-triaryl amine compounds that span a range of multi-electron oxidation potentials. The compounds feature good solubility in acetonitrile and an exceptionally high oxidation potential compared to usual low oxidation potentials of such compounds. Radical cations of the compounds were synthesized and isolated as PF.sub.6.sup. salts and characterized. Use of the compounds in a symmetrical RFB showed high cycling stability and capacity retention.
