A novel Ag-Cu bimetallic nanocluster, Ag40.13Cu13.87S19(tBuS)20(tBuSO3)12, has been synthesized by precise control. The crystal structure reveals that the alloy cluster consists of a Cu10Ag2S7 core, a M42(tBuS)20(tBuSO3)12 shell and another 12 bare S atoms. The sulfonate ligand is observed in NCs for the first time via in situ oxidation of thiolate.
通过精确控制合成了一种新型的Ag-Cu双金属纳米团簇Ag40.13Cu13.87S19(tBuS)20(tBuSO3)12。晶体结构表明，该合金团簇由一个Cu10Ag2S7核、一个M42(tBuS)20(tBuSO3)12壳层以及另外12个裸S原子组成。通过硫醇盐的原位氧化首次在纳米团簇中观察到了磺酸酯配体。
