Hierarchical nano structures are hard to fabircate. Here, we present three novel hierarchical multi-shell 66-nuclei silver nanoclusters, trapping ultrasmall Ag64+ nano-fragments by nine MoO42- ions. This Ag6@(MoO4)9 core is further wrapped by an outer Ag60 shell. The Ag6 kernel evolves from reduction involving DMF solvent. Carboxylate ligands are very important in the modulation of the polygon patterns on the Ag60 shell.
分层纳米结构很难制造。在此，我们展示了三种新型的分层多壳66核银纳米簇，由九个MoO42-离子捕获超小的Ag64+纳米碎片。这个Ag6@(MoO4)9核进一步被一个外部的Ag60壳包裹。Ag6核由涉及N,N-二甲基甲酰胺（DMF）溶剂的还原反应演变而来。羧酸盐配体在调节Ag60壳上的多边形图案方面非常重要。
