The redox-active IL was shown to exhibit the same ion selectivity as the structurally similar but redox-inactive tridodecylmethylammonium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate. Ion transfer potentials evaluated from CV measurements allowed establishing the scale of absolute potential differences for the interfacial oxidation of FcMDDA+ with the aqueous redox species including IrCl62−, Fe(CN)63−, Mo(CN)83−, ICl2− or IBr2−. In order to rationalize experimental data, the theory of CV was developed for an electron transfer at one membrane interface that is coupled with the ion transfer at the other membrane interface.
