spectroscopy (FT-IR). For the first time, the trivalent tetrahedron anion of AsO43-, as a template, and the surface ligand of Ph2PO2H, with new coordination modes, were employed in preparation of the silver clusters. The role of surface ligands and template anions in the size and structure of the clusters was investigated. The presence of the template in the structure of the clusters led to the formation of the
具有所需结构的新型高核银团簇的合成和自组装过程的控制对材料科学和许多应用都是重要的。本文中,基于炔基配体构建了三个新的银团簇,分别为20、22和8核,并通过单晶X射线衍射,粉末X射线衍射,元素分析和傅里叶分析确定了它们的结构。变换红外光谱(FT-IR)。首次以AsO43-的三价四面体阴离子为模板,并以新的配位方式使用Ph2PO2H的表面配体制备银簇。研究了表面配体和模板阴离子在簇的大小和结构中的作用。簇结构中模板的存在导致了高核簇的形成。而且,在该报告中,表明了模板在簇的组装中的参与可以由表面配体控制。还研究了团簇的紫外可见吸收和发光特性以及八核团簇的热稳定性。
