Abstract

Aromatic trifluoroborate ([Ar-BF₃]-) is a useful anion structure for molten salt and ionic liquid (IL) designing because we can attach various sorts of substituents on the aromatic ring with ease. A number of alkali metal salts having [Ar-BF₃]- were synthesized and their physical properties were measured. The salts showed lower melting point than simple inorganic salt, e.g., KCl and LiCl. When phenyltrifluoroborate ([PhBF3]^-) and 1-ethyl-3- methylimidazolium ([C2mim]⁺) or 1-butyl-3-methylimidazolium ([C4mim]⁺) were combined, the resulting salts became a liquid state at room temperature. These ILs exhibited favorable viscosity and ionic conductivity comparable to a typical IL species, [C4mim][BF₄].
