Supramolecular chemistry (SC) of noble metal nanoclusters (NMNCs) is one of the fascinating areas of contemporary materials science. It is principally concerned with the noncovalent interactions between NMNCs, as well as between NMNCs and molecules or nanoparticles. This review focuses on recent advances in the supramolecular assembly of NMNCs and applications of the resulting structures. We have divided the topics into four distinct subgroups: (i) SC of NMNCs in gaseous and solution phases, (ii) supramolecular interactions of NMNCs in crystal lattices, (iii) supramolecular assemblies of NMNCs with nanoparticles and NMNCs, and (iv) SC of NMNCs with other molecules. The last explores their interactions with fullerenes, cyclodextrins, cucurbiturils, crown ethers, and more. After discussing these topics concisely, various emerging properties of the assembled systems in terms of their mechanical, optical, magnetic, charge-transfer, etc. properties and applications are presented. SC is seen to provide a crucial role to induce new physical and chemical properties in such hybrid nanomaterials. Finally, we highlight the scope for expansion and future research in the area. This review would be useful to those working on functional nanostructures in general and NMNCs in particular.
贵金属纳米团簇（NMNCs）的超分子化学（SC）是当代材料科学中一个引人入胜的领域。它主要关注NMNCs之间以及NMNCs与分子或纳米颗粒之间的非共价相互作用。本综述重点介绍了NMNCs超分子组装的最新进展以及所得结构的应用。我们将主题分为四个不同的子组：（i）气相和溶液相中NMNCs的超分子化学，（ii）晶格中NMNCs的超分子相互作用，（iii）NMNCs与纳米颗粒和NMNCs的超分子组装，以及（iv）NMNCs与其他分子的超分子化学。最后一部分探讨了它们与富勒烯、环糊精、葫芦脲、冠醚等的相互作用。在简要讨论这些主题之后，介绍了组装体系在机械、光学、磁性、电荷转移等性质和应用方面的各种新兴特性。超分子化学在诱导此类杂化纳米材料产生新的物理和化学性质方面起着关键作用。最后，我们强调了该领域的扩展范围和未来研究方向。本综述对一般从事功能纳米结构研究，特别是从事NMNCs研究的人员将有所帮助。
