摘要：

We present the cluster-to-cluster transformations among three gold nanoclusters, [Au-6 (dppp)(4)](2+) (Au-6), [Au-8(dPPP)(4)O-2](2+) (Au-8) and (Au-11(dPPP)(5)](3+) (Au-11). The conversion process follows a rule that states that the transformation of a small cluster to a large cluster is achieved through an oxidation process with an oxidizing agent (H2O2) or with heating, while the conversion of a large cluster to a small one occurs through a reduction process with a reducing agent (NaBH4). All the reactions were monitored using UV-Vis spectroscopy and ESI-MS. This work may provide an alternative approach to the synthesis of novel gold nanoclusters and a further understanding of the structural transformation relationship of gold nanoclusters.
