金纳米粒子覆盖着一个横向连接通过硫代烷基间隔和硫代烷烃的液晶配体的“稀释剂”表现出三维有序的字符串夹套的介晶与可控的粒子间的间距。粒子形成菱面体、六方和矩形柱状超晶格，而不是通常的球形堆积模式。
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.
