摘要
On ionic liquids having functional groups in the side chain of their imidazolium cations, their characterization has been carried out. The ion conduction properties of the lithium salt solutions of these ionic liquids have also been investigated Proton NMR measurement reveals that CmMI cation has a tendency of charge localization than other imidazolium cations. Among the ionic liquids investigated, only the one having CmMI cation exhibit conductivity increase when it dissolves small amount of lithium salt. Raman spectra for the lithium salt solutions indicate that the CmMI-based ionic liquid provides different status of lithium ion compared with EMI-based ionic liquid. Such a difference appears to come from the difference in electronic structure of imidazolium cation.
