Ligand structure could control the size and structure of thiolate-protected silver nanoclusters (Ag NCs) in water. Small alkane-thiols, medium-sized aromatic-thiols, and bulky thiol-containing tri-peptides direct the formation of Ag(SR), Ag(SR), and Ag(SR), respectively. In addition, small alkane-thiol collocates well with other types of thiolate ligand to generate bi-thiolate-protected Ag NCs with controlled ligand landscapes on their surfaces.
配体结构可以控制水中硫醇盐保护的银纳米簇（Ag NCs）的尺寸和结构。小分子链烷硫醇、中等大小的芳族硫醇和含硫醇的大分子三肽分别引导形成Ag(SR)₂、Ag(SR)₃和Ag(SR)₄。此外，小分子链烷硫醇能与其他类型的硫醇盐配体很好地配位，生成表面具有可控配体分布的双硫醇盐保护的Ag NCs。
