Fascinating nematic- and smectic-like self-assembled arrays are observed for gold nanorods partially capped with either laterally or terminally substituted nematic liquid crystals upon slow evaporation of an organic solvent on transmission electron microscopy (TEM) grids. These arrays can be manipulated and reoriented by applying an external magnetic field from quasi-planar to vertical similar to a Fréedericksz transition of common organic nematic liquid crystals.
