A facile route was demonstrated for inorganic Sn-X-complex-induced syntheses of self-assembled 1D columnar, 2D raftlike, and 3D stratiform anisotropic Cu(2)S hexagonal nanoplates. The factors (reaction time, temperature, the concentration of Sn-X complex, and so on) that influence the size, phase, monodispersity, and self-assembly ability of the Cu(2)S hexagonal nanoplates were studied in detail. It was found that the Sn-X complex could inhibit the growth of the <001> direction of monoclinic Cu(2)S nanocrystals, which further induced the formation of the hexagonal lamellar structure. Furthermore, it revealed that the formation of the 1D arrangement was preferred as particles stacked in a face-to-face configuration by maximizing ligand-surface interactions. Then, high ligand density along the side of the 1D columnar arrangement induced well-defined 2D raftlike and 3D stratiform self-assembly.
一种简便的路线被证明可以用于无机 Sn-X 配合物诱导的自组装一维柱状、二维筏状和三维层状各向异性 Cu(2)S 六方纳米片的合成。详细研究了影响 Cu(2)S 六方纳米片的尺寸、相、单分散性和自组装能力的因素（反应时间、温度、Sn-X 配合物的浓度等）。发现 Sn-X 配合物可以抑制四方晶系 Cu(2)S 纳米晶的<001>方向生长，进一步诱导形成六方片状结构。此外，研究表明，由于颗粒以面对面的方式堆积，通过最大化配体-表面相互作用，1D 排列的形成是首选的，然后，沿着 1D 柱状排列的侧面高配体密度诱导了明确的二维筏状和三维层状自组装。
