Metal nanoclusters (NCs), which consist of several, to about one hundred, metal atoms, have attracted much attention as functional nanomaterials for use in nanotechnology. Because of their fine particle size, metal NCs exhibit physical/chemical properties and functions different from those of the corresponding bulk metal. In recent years, many techniques to precisely synthesize metal NCs have been developed. However, to apply these metal NCs in devices and as next-generation materials, it is necessary to assemble metal NCs to a size that is easy to handle. Recently, multiple techniques have been developed to form one-, two-, and three-dimensional connected structures (CSs) of metal NCs through self-assembly. Further progress of these techniques will promote the development of nanomaterials that take advantage of the characteristics of metal NCs. This review summarizes previous research on the CSs of metal NCs. We hope that this review will allow readers to obtain a general understanding of the formation and functions of CSs and that the obtained knowledge will help to establish clear design guidelines for fabricating new CSs with desired functions in the future.
由几个到大约一百个金属原子组成的金属纳米团簇（NCs）作为用于纳米技术的功能纳米材料已引起广泛关注。由于其精细的粒径，金属纳米团簇表现出与相应块状金属不同的物理/化学性质和功能。近年来，已开发出许多精确合成金属纳米团簇的技术。然而，要将这些金属纳米团簇应用于器件和作为下一代材料，有必要将金属纳米团簇组装到易于处理的尺寸。最近，已开发出多种技术，通过自组装形成金属纳米团簇的一维、二维和三维连接结构（CSs）。这些技术的进一步发展将促进利用金属纳米团簇特性的纳米材料的开发。本综述总结了先前关于金属纳米团簇连接结构的研究。我们希望本综述能使读者对连接结构的形成和功能有一个总体了解，并且所获得的知识将有助于在未来建立明确的设计指南，以制造具有所需功能的新型连接结构。
