Microwave-Assisted Synthesis and Mesomorphic Properties of Novel Unsymmetric Imidazolium as Ionic Liquid Crystals

Article Preview

Abstract:

Two kinds of novel unsymmetric imidazolium salts based ionic liquid crystals (1- [4-(dodecyloxy) phenyl]-3-hexyl/octyl-1H-imidazol-3-ium bromide) were efficiently prepared using a microwave-assisted method. Their mesomorphism has been fully investigated by POM and DSC. The two imidazolium salts displayed typical and good smectic phase textures.
