Materials study demonstrates 3D ordered gold nanoparticle strings jacketed by mesogens, indicating novel non-spherical superlattice self-assembly routes.
Gold nanoparticles covered with a nematic liquid-crystal ligand laterally attached via a thioalkyl spacer and a thioalkane “diluent” exhibit 3D ordering in strings jacketed by the mesogens with controllable interparticle spacing. The particles form rhombohedral, hexagonal, and rectangular columnar superlattices, not the usual packing modes of spheres.
