| Abstract: | Ten halogen-free ionic liquids(ILs) based on 1,3-dialkylimidazolium cations and methanesulfonate -or p-toluenesulfonate -anions were synthesized via one-step reaction,and their physicochemical properties such as aggregation behavior,surface property,thermal property,density,viscosity,refractive index and electrochemical properties have comparatively been studied.The results showed that ion cluster behavior was observed for the methanesulfonate anion ILs.The emission spectra of neat MS only gave relatively w... |
