In order to study the charge effect on the formation of an anion-templated silver cluster, a trivalent tetrahedral anion was incorporated into the silver assembly. A 26-nuclear silver cluster was prepared, and its structure was confirmed by single-crystal X-ray diffraction. Also, the resulting structure was characterized by powder X-ray diffraction data. Its light absorption and photoluminescent properties were studied by solid-state UV diffuse-reflectance and fluorescence spectroscopy. Compared with the other reported silver clusters with tetrahedral anion templates, the more negative VO anion led to the formation of a bigger silver cluster. Also, the supramolecular motif O-H(CHOH)···O(trifluoroacetate) was confirmed on the cluster surface for the first time.
为了研究电荷对阴离子模板化银簇形成的影响，将一种三价四面体阴离子引入银组装体中。制备了一个26核银簇，并通过单晶X射线衍射确定了其结构。此外，所得结构通过粉末X射线衍射数据进行表征。通过固态紫外漫反射和荧光光谱研究了其光吸收和光致发光性质。与其他报道的具有四面体阴离子模板的银簇相比，更负的VO阴离子导致形成更大的银簇。此外，首次在簇表面确认了超分子基序O-H(CHOH)···O(三氟乙酸根)。
