Abstract

Phase transition behavior of imidazolium dodecylsulfonate was considerably affected by the introduction of methyl groups onto the imidazolium cation ring. Methyl group on the 2- position eliminated the liquid crystallinity. That on the 4-position was effective to suppress the crystallization.
