General description

1-Ethyl-3-methylimidazolium tetrafluoroborate is an air and water stable, room temperature ionic liquid (RTIL). It can be prepared by reacting 1-ethyl-3-methylimidazolium bromide with tetrafluoroboric acid.

Application


  • 1-Ethyl-3-methylimidazolium tetrafluoroborate-doped high ionic conductivity gel electrolytes with reduced anodic reaction potentials for electrochromic devices: This study reports the preparation of a 1-Ethyl-3-methylimidazolium tetrafluoroborate ([Emim] BF4)-doped Poly(methyl methacrylate)(PMMA)-based gel electrolyte for electrochromic applications, showing improved ionic conductivity and reduced anodic reaction potentials (Tang et al., 2017).
