| 摘 要： | 通过一锅还原法成功制备了合金纳米团簇Au11-xCux(dppf)4Cl2(x=1、2；dppf=1，1''-双(二苯基膦)二茂铁)。晶体结构解析表明，合金团簇具有与 Au11(dppf)4Cl2类似的几何结构，如含有缺陷二十面体金属内核，不同之处在于 Cu原子取代了与 Cl配位的Au原子。因此，Au11-xCux(dppf)4Cl2可视为Cu对Au11(dppf)4Cl2模板团簇的掺杂。Cu原子的引入并未改变模板团簇Au11(dppf)4Cl2的框架结构，但有效调控了电子结构，进而使其光吸收发生红移。

| Abstract: | An alloy nanocluster of Au11-xCux(dppf)4Cl2 (x=1, 2; dppf=1, 1'' - bis(diphenylphosphine) ferrocene) was synthesized via a one - pot reduction method. X - ray crystallography shows that this nanocluster has a defective icosahedral core, which is analog to that of Au11(dppf)4Cl2. The difference lies in that Cu atoms replace the inner shell Au atoms that are coordinated with the Cl atom. Therefore, Au11-xCux(dppf)4Cl2 can be regarded as Cu-doped Au11(dppf)4Cl2. The introduction of Cu atoms exerts an influence on the electronic property of the template nanocluster with the structural framework maintained, further resulting in a red shift of the optical absorption. |
