A new class of double alkyl-substituted, liquid crystalline imidazolium ionic liquids--a unique combination of structural features, viscosity effects, and thermal properties.
1,3-Didodecylimidazolium salts have been prepared as first representatives of a new class of ionic liquid crystals (ILCs), showing thermotropic liquid crystalline behaviour in an extended temperature range below 70 degrees C. Remarkably strong non-Newtonian viscosity behaviour was found for the liquid-crystalline state of these ILCs.
