Two-dimensional (2D) nanomaterials with the thickness at atomic level are promising candidates for a wide range of applications, and now reach the point to create diversified 2D architectures. The colloidal synthesis route is powerful to produce crystalline nanosheets, nanoribbons and nanoplatelets, and the self-assembly strategy is robust to integrate the functionalities of different nano-objects. In this review, we bridge the colloidal synthesis of nanosheets and the 2D self-assembly of nanoclusters (NCs) with the aim to further optimize the physical and chemical properties of 2D nanomaterials. Ultrasmall NCs, the intermediate for synthesizing nanosheets, are highlighted to show the similarity of 2D crystallization and 2D self-assembly. The modification of conventional 2D colloidal synthesis route greatly permits the controlled self-assembly of NCs into free-standing monolayers in colloidal solutions.
二维（2D）纳米材料的厚度达到原子级，有望在广泛的应用中得到应用，现在已经达到了创造多样化 2D 结构的地步。胶体合成途径是制备结晶纳米片、纳米带和纳米板的有力手段，而自组装策略则能够将不同纳米物体的功能集成在一起。在这篇综述中，我们将纳米片的胶体合成和纳米团簇（NCs）的二维自组装联系起来，旨在进一步优化二维纳米材料的物理和化学性质。我们强调超小的 NCs 作为合成纳米片的中间体，以展示二维结晶和二维自组装的相似性。对传统的 2D 胶体合成途径的修改极大地允许了 NCs 在胶体溶液中的自由组装成独立的单层。
