|Outline of Final Research Achievements
Room-temperature ionic liquids (RTILs), which are salts in a liquid phase at room temperature, have attracted much interest as totally new fluids due to their unique nature, such as nonvolatility, nonflamability, high ion transportation, and wide electrochemical window. In this study, we have carried out a series of experiments, by using nonlinear vibrational spectroscopy, to elucidate interfacial structure and related functionality of RTILs from physico-chemical and/or molecular scientific view-points. We have successfully demonstrated that Stern layer may not exist at RTIL/electrolyte interfaces. We have also found the effect of the extension of electrochemistry window of ionic liquids by an addition of Li+ cations.
