Mesomorphic Properties

The recently introduced concept of ionic liquid crystals (ILCs) with complementary ion pairs, consisting of both, mesogenic cation and anion, was extended from guanidinium sulfonates to guanidinium sulfonimides. In this preliminary study, the synthesis and mesomorphic properties of selected derivatives were described, which provide the first example of an ILC with the sulfonimide anion directly attached to the mesogenic unit.

Microwave Assisted Method

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.
