The polarized potential window at the room-temperature molten salt (RTMS)|water (W) interface can be widened using RTMSs composed of a hydrophobic anion, tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (TFPB). The cations which we used for TFPB-based salts are 1-alkyl-3-methylimidazolium (C nmim+: n = 2,4-8,10,12), N-dodecylpyridinium (C nPy+), trioctylmethylammonium (TOMA+), and N-alkylisoquinolinium (CnIq+, n = 12, 18). Among the RTMSs investigated, [C18Iq][TFPB] is in the liquid state at room temperature. The width of the potential window of [C18Iq][TFPB]|W interface is 800 mV, which allows us to study the transfer of moderately hydrophilic cations and moderately hydrophobic anions across the interface.

Proceedings - Electrochemical Society PV 2004-24 519 - 522 2006

Novel fluorine-free and water-immiscible room-temperature molten salts (RTMSs) composed of symmetrical tetraalkylammonium (Nnnnn· n: length of alkyl chain, n = 4-8) and diisooctylsulfosuccinate (DOSS) have been synthesized. Density, conductivity, and water content of the water-saturated RTMSs at 25°C have been measured. Cyclic voltammograms at the N nnnnDOSS|water interfaces show that the interfaces are polarizable and the width of the potential window at the N6666DOSS |water interface is ca. 300 mV.
