data, density functional calculations, and electron spectroscopy. The structure of the complex of 4′-(4-methylsulfanyl)-2,2′:6′,2"-terpyridine with Ni(BF4)2 was also established by X-ray diffraction analysis. A method was proposed for the preparation of gold nanoparticle dimeric aggregates via coordination interactions of the ligands adsorbed on the gold nanoparticle surface with transition metal ions
开发了合成有机亲金配体的方法,即含硫 2,2':6',2'-三联吡啶衍生物。研究了具有苯硫酚、二芳基二硫化物和烷基芳基硫化物片段的三联吡啶配体与 Coii、Niii 和 Rhiii 盐的络合反应。基于元素分析数据、密度泛函计算和电子能谱确定了所获得的配位化合物的结构。4'-(4-甲基硫烷基)-2,2':6',2"-三联吡啶与Ni(BF4)2配合物的结构也通过X射线衍射分析确定。提出了制备方法金纳米颗粒二聚体聚集体通过吸附在金纳米颗粒表面的配体与过渡金属离子的配位相互作用。
