摘要
金属纳米簇具有与分子相似的结构和性质,在催化、发光、生物探针以及分子电子学等领域有重要的应用前景~1,明晰金属纳米簇的设计合成和结构组成对分子表/界面的成键方式以及构效关系有重要的理论意义~2。从低核分子簇出发,我们得到一例25核金/银异金属纳米簇(Fig.1),其不对称单元是一个7金6银的13核"魔术笼"。整个分子大小约为22×18 A,头脚部和腰部分别由外围的膦配体和氯离子保护。
Metal nanoclusters(NCs) are interesting because of their molecule-like structures and properties and also their application in catalysis,luminescence,biosensing and molecular electronics.It is important to understand the interfacial bonding and correlation between structure and properties through the synthetic procedure and structural determination.In this regard,we prepared a heterometallic Au/Ag-NCs with 25 metal atoms,with 7 Au and 6 Ag in asymmetric unit which form a magic cage.The molecule with size of 22×18 A is protected by phosphine and Cl~-.
