Abstract: | Here we report the synthesis of a new redox-active ionic liquid (IL), (ferrocenylmethyl)dodecyldimethylammonium tetrakis3,5-bis(trifluoromethyl)phenyl]borate that can be used to form the polarizable water│IL interface at an elevated temperature (43 °C). Experimental approach is based on the cyclic voltammetry of the charge transfer processes occurring at the IL membrane supported on a thin microporous filter. Evidence is provided of the interfacial electron transfer between the ferrocenated cation of IL and an electron acceptor, IrCl62?, in the adjacent aqueous phase. |
