在此，我们报告了18种新型含硫磷鎓阳离子的液体性质，即密度、粘度、电导率、表面张力、熔点和玻璃化转变温度，（三乙基[（甲硫基）甲基] 鏻、三乙基[2-（三氟甲基）苯基]甲基）鏻、（甲硫基）乙基]鳞、三乙基[2-（2-（2-甲氧基乙基）乙基]鳞（乙硫基）乙基]三丁基[（甲硫基）甲基]三丁基[2-（甲硫基）乙基]鳞、三丁基[2-（乙硫基）乙基]鳞）基离子液体，其具有双（三氟甲基磺酰基）酰胺、双（氟磺酰基）酰胺和四氟硼酸根阴离子。烷硫基烷基对离子液体粘度和表面张力的影响与典型离子液体中常见的烷基有很大的不同。
Herein, we report the liquid properties, that is, densities, viscosities, electrical conductivities, surface tensions, melting points, and glass transition temperatures, of 18 novel sulfur-containing phosphonium cation- (triethyl[(methylthio)methyl]phosphonium, triethyl[2-(methylthio)ethyl]phosphonium, triethyl[2-(ethylthio)ethyl]phosphonium, tributyl[(methylthio)methyl]phosphonium, tributyl[2-(methylthio)ethyl]phosphonium, tributyl[2-(ethylthio)ethyl]phosphonium) based ionic liquids with bis(trifluoromethylsulfonyl)amide, bis(fluorosulfonyl)amide, and tetrafluoroborate anions. The effects of the (alkylthio)alkyl groups on the viscosity and surface tension of the ionic liquids are very different from those of common alkyl groups in typical ionic liquids.
