The assembly of atomically precise clusters into superstructures has tremendous potential in structural tunability and applications. Here, we report a series of single-cluster nanowires, single-cluster nanorings, and three-dimensional superstructure assemblies built by POM clusters. By stepwise tuning of interactions at molecular levels, the configurations can be varied from single-cluster nanowires to nanorings. A series of single-cluster nanostructures in different configurations can be achieved with up to 15 kinds of POM clusters. The single-cluster nanowires and three-dimensional superstructures perform enhanced activity in the catalytic and electrochemical sensing fields, illustrating the universal functionality of single-cluster assemblies.
将原子精确的团簇组装成超结构在结构可调性和应用方面具有巨大潜力。在此，我们报道了一系列由多金属氧酸盐（POM）团簇构建的单团簇纳米线、单团簇纳米环和三维超结构组件。通过在分子水平上逐步调节相互作用，其构型可从单团簇纳米线转变为纳米环。利用多达15种POM团簇可实现一系列不同构型的单团簇纳米结构。单团簇纳米线和三维超结构在催化和电化学传感领域表现出增强的活性，说明了单团簇组装体具有通用功能性。
