Homology is well known in organic chemistry; however, it has not yet been reported in nanochemistry. Herein, we introduce the concept of kernel homology to describe the phenomenon of metal nanoclusters sharing the same "functional group" in kernels with some similar properties. To illustrate this point, we synthesized two novel gold nanoclusters, Au (TBBT) and Au (TBBT) (TBBTH=4-tert-butylbenzenethiol), and solved their total structures by X-ray crystallography, which reveals that they have the same Au bi-icosahedron capped with a similar bottom cap (Au and Au , respectively) in the kernels. The two novel gold nanoclusters, together with the existing Au (PET) nanocluster (PETH=phenylethanethiol), have the same "functional group"-Au -in their kernels and have some similar properties (e.g., electrochemical properties); therefore, they are comparable to the homologues in organic chemistry.
同系现象在有机化学中广为人知;然而,在纳米化学中尚未有相关报道。在此,我们引入核同系的概念来描述金属纳米团簇在核中共享具有某些相似性质的相同“官能团”的现象。为说明这一点,我们合成了两种新型金纳米团簇,Au(TBBT)和Au(TBBT)(TBBTH = 4-叔丁基苯硫酚),并通过X射线晶体学解析了它们的完整结构,结果表明它们在核中具有相同的金双二十面体,顶部覆盖着相似的底帽(分别为Au和Au)。这两种新型金纳米团簇与现有的Au(PET)纳米团簇(PETH = 苯乙硫醇)在核中具有相同的“官能团”——Au,并且具有一些相似的性质(例如电化学性质);因此,它们可与有机化学中的同系物相媲美。
