Branched quaternary ammonium amphiphiles: nematic ionic liquid crystals near room temperature

摘要

Branched quaternary ammonium molecules were synthesized and characterized by calorimetric, optical and X-ray diffraction studies; two of the molecules exhibited interesting nematic liquid crystalline behavior close to room temperature.rnIn this communication, we report nematic ionic liquid crystals (ILCs) formed near room temperature. ILCs that combine both the solvent properties of ionic liquids and the, self-organization features of liquid crystals, have been of considerable interest in recent years because they present unique potential applications lacking in normal liquid crystals.
