| Outline of Final Research Achievements |
Bis(trifluoromethanesulfonyl)imide have been frequently used as the counter anions in ionic liquids. Its ability to lower the melting point because of weakening of electrostatic interaction is still under debate. In this study, we examined the relationship between the fluoroalkyl chain length of bis (fluoroalkanesulfonyl)imide the melting point of methyl viologen salts. We found that the appropriate combinations of chain length of viologens and anions are required for the lower melting of viologen salts. In addition, we examined electric transportation properties of a viologen type ionic liquid, 1-butyl,1’-heptyl-viologen dibis(trifluoromethanesulfonyl)imide, by cyclic voltammetry (CV) and NMR measurement. We found that the physical diffusion is dominant for the apparent diffusion by the CV measurement.
