<p>2-Heptadecylimidazole (a) neutralized with a series of acids showed good thermal stability. The decomposition temperature of most salts exceeded 200 °C. Among these, a neutralized with HBF4 showed enantiotropic liquid crystalline phase. Higher ionic conductivity and lower activation energy were found for the salt in the liquid crystalline phase. The a neutralized with HBF4 was mixed with 11 mol% a to introduce the proton acceptor sites in the assembled a. The mixture showed a monotropic liquid crystalline phase. High ionic conductivity and low activation energy were also seen in the monotropic liquid crystalline phase.</p>
