Ion-Transfer Voltammetry at a Polarized Room-Temperature Molten Salt | Water Interface

抄録

Tetraoctylammonium cation forms a room-temperature molten salt (RTMS) with 2,4,6-trinitrophenolate anion. The RTMS is immiscible with water (W) and forms a stable RTMS | W interface. It has been shown that the RTMS | W interface can be electrochemically polarized. A well-defined voltammetric wave due to the transfer of thiocyanate ion across the RTMS | W interface was observed within the potential window. This is the first example of a polarized RTMS | W interface.
