摘　　要：For nanochemistry, precise manipulation of nanoscalestructures and the accompanying chemical properties atatomic precision is one of the greatest challenges today. Thescientific community strives to develop and design customizednanomaterials, while molecular interactions often serve as key toolsor probes for this atomically precise undertaking. In thisPerspective, metal nanoclusters, especially gold nanoclusters,serve as a good platform for understanding such nanoscaleinteractions. These nanoclusters often have a core size of about 2nm, a defined number of core metal atoms, and protecting ligandswith known crystal structure. The atomically precise structure ofmetal nanoclusters allows us to discuss how the molecularinteractions facilitate the systematic modification and functionalization of nanoclusters from their inner core, through the ligandshell, to the external assembly. Interestingly, the atomic packing structure of the nanocluster core can be affected by forces on thesurface. After discussing the core structure, we examine various atomic-level strategies to enhance their photoluminescent quantumyield and improve nanoclusters’ catalytic performance. Beyond the single cluster level, various attractive or repulsive molecularinteractions have been employed to engineer the self-assembly behavior and thus packing morphology of metal nanoclusters. Themethodological and fundamental insights systemized in this review should be useful for customizing the cluster structure andassembly patterns at the atomic level.
