Abstract

A trifluoromethanesulfonate (OTf) and -butylacetylene ( BuC[triple bond, length as m-dash]C) co-protected silver nanocluster (NC), Ag( BuC[triple bond, length as m-dash]C)(CFSO) (Ag), was synthesized and characterized. Single crystal X-ray diffraction analysis revealed its total structure. 43 Ag atoms are arranged into a three-concentric-shell Ag@Ag@Ag structure. Both OTf and BuC[triple bond, length as m-dash]C ligands bonded with Ag atoms in a μ mode. The application of Ag as a catalyst for the reaction of silane with alcohol or HO indicated that the surface ligands had a profound passivation effect, which significantly influenced the reactivity and selectivity.

摘要

合成并表征了一种三氟甲磺酸根（OTf）和叔丁基乙炔（t-BuC≡C）共保护的银纳米簇（NC），即Ag(t-BuC≡C)(CF₃SO₃)（Ag₁₀₂）。单晶X射线衍射分析揭示了其整体结构。43个银原子排列成一个三同心壳层的Ag@Ag@Ag结构。OTf和t-BuC≡C配体均以μ模式与银原子键合。将Ag₁₀₂用作硅烷与醇或H₂O反应的催化剂表明，表面配体具有显著的钝化作用，这对反应活性和选择性有重大影响。
