Low Melting and Electrochemically Stable Ionic Liquids Based on Asymmetric Fluorosulfonyl(trifluoromethylsulfonyl)amide
An asymmetric amide anion, FTA(-) {[(FSO2)(CF3SO2)-N](-)}, has a significant ability to reduce the melting points of an aliphatic quaternary ammonium salts even for a symmetric tetraethylammonium. Much more interestingly, the electrochemical stability of this anion was comparable to a typical amide anion, such as bis(trifluoromethylsulfonyl)amide.
