Ionic liquid crystals: Self-assembly of imidazolium salts containing an L-glutamic acid moiety

Liquid-crystalline (LC) behavior and ionic conductivities of imidazolium salts containing an L-glutamic acid moiety have been studied. The ionic conductivities of the (CF(3)So(2))(2)N- salt forming the columnar LC phase are higher than those of the Br- salt in the columnar LC state. The ionic conductivity shows a sudden decrease at the columnar-micellar cubic LC transition of the Br- salt.
