Herein, we describe a facile synthesis of stable chiral ionic liquid crystal (ILC)-capped gold nanoparticles. A new ILC containing a chiral cholesterol moiety having a terminal triethylammonium group was synthesized which exhibited an enantiotropic lamellar mesophase. Stable, monodisperse citrate-stabilized gold nanoparticles having a size of ∼60 nm were prepared and the citrate ligands on the gold nanoparticles were replaced with chiral ILC through a two-phase ligand exchange process. The resulting chiral ILC-stabilized particles were characterised using UV-visible (UV-Vis) and transmission electron microscopy (TEM) studies. Different from the citrate-stabilized nanoparticles, the ligand exchanged gold nanoparticles were dispersible in organic solvent and resulting dispersion was stable for more than observed period of 3 mo. Furthermore, the chiral ILC-decorated gold nanoparticles were found to be well dispersible in a nematic host without any aggregation and induced a vertical alignment of the nematic director.
