Liquid state halide salts composed of imidazolium cations having allyl groups were prepared. Their ionic conductivity, viscosity, and thermal properties were investigated. Introduction of allyl group on N-position effectively suppressed the crystallization of the corresponding salts. 1,3-diallyl imidazolium halides therefore showed considerably lower viscosity and higher ionic conductivity than other halide salts.
A novel imidazolium compound represented by the following general formula (I),
which has an allyl group incorporated in the 3-position of the imidazolium ring. It needs no complicated operations for dissolution and has excellent handleability and a high ionic conductivity.
