For five years of the MEXT project of "Science of Ionic Liquids", our group has started and carried out a couple of subjects related to the surfaces and interfaces of room temperature ionic liquids (RTIL) ; i) IR-Vis sum-frequency generation (IV-SFG) study on the air/liq interface of RTILs and their aqueous solutions, ii) Vibrational spectroscopic study (IR, Raman) on RTILs and their aqueous solutions, iii) X-ray reflectivity study on the air/liq interface of RTILs, iv) UPS, IPES and MAES studies of RTILs for their electronic structure, v) Soft X-ray emission spectroscopy of RTILs, vi) Electrochemical IV-SFG study on the metal/liq interface of RTILs vii) IV-SFG study on the liq/liq interface of RTILs. We have found that the interfaces are made of polar-oriented cations and anions to reduce surface and interface tensions. We have observed Madelung-potential to be 4-5 eV, which is much smaller than those of conventional ionic crystals.

在“离子液体科学”MEXT项目的五年里，我课题组已经启动并开展了一些与室温离子液体（RTIL）表面和界面相关的课题；i) RTILs及其水溶液空气/液相界面的IR- vis和频生成（iv - sfg）研究，ii) RTILs及其水溶液的振动光谱研究（IR, Raman）， iii) RTILs空气/液相界面的x射线反射率研究，iv) RTILs电子结构的UPS， IPES和MAES研究，v) RTILs的软x射线发射光谱，RTILs金属/液界面的电化学IV-SFG研究我们发现界面由极性取向的阳离子和阴离子组成，以降低表面和界面张力。我们观察到马德隆势在4-5 eV，比传统离子晶体的马德隆势小得多。
