The synthesis of atom-precise analogues of homometallic nanoclusters remains a great challenge. Herein we report the first pair of atom-precise copper/silver-thiolate halide cluster analogues, namely [Cu17/Ag17I3S(C2B10H10S2)6(CH3CN)11] (Cu17 and Ag17), obtained by bottom-up self-assembly and complete-metal-exchange-induced cluster-to-cluster transformation, respectively. The differences in optical absorption and emission of these analogues were fully elucidated by experimental and theoretical methods.
原子精度的同核纳米团簇类似物的合成仍然是一个巨大的挑战。在此,我们报道了第一对原子精度的铜/银-硫醇卤化物团簇类似物,即 [Cu17/Ag17I3S(C2B10H10S2)6(CH3CN)11](Cu17 和 Ag17),分别通过自下而上的自组装和完全金属交换诱导的簇到簇的转化获得。通过实验和理论方法充分阐明了这些类似物在光学吸收和发射方面的差异。
