PA17 Zwitterionic liquid crystalline compounds for construction of lithium ion containing ionic liquid crystals

Abstract

Novel zwitterionic liquid crystalline compounds possessing imidazolium or ammonium as a cationic part and carboxylate as a counter ion were synthesized. Their phase transition behaviors and also the effect of the addition of lithium salts was examined. Their liquid crystalline behaviors and superstructures were investigated by polarized optical microscopy (POM) and X-ray diffraction (XRD). Hexagonal columnar structure was observed as the mesophases for both with and without the addition of lithium salts.
