文摘New functionalized ionic liquids, 1-carboxylmethyl-3-methylimimidazolium hexafluorophosphate or fluoborate and 1-aminoethyl-3-methylimimidazolium hexafluorophosphate or fluoborate have been synthesized and investigated. The obtained amino or carboxyl-functionalized ionic liquids were all characterized by FT-IR, ^1H NMR and MS （ESI） and their properties such as freezing point, viscosity, solubility, specific gravity, surface tension, and interfacial tension were also determined.
