Cover Story: Superatoms are promising materials for their potential as new building blocks. Thus far, various synthesis methods of thiol-protected Au clusters, including an Au25 superatom, have been investigated. However, previously reported methods mainly depended on the thermodynamic stability of clusters. By contrast, direct synthesis with atomicity control process enables rapid synthesis and heterogeneous atom blending by the corresponding precursors. This report proposes a synthesis method for thiol-protected Au clusters using a dendrimer template. In this method, the number of Au atoms was controlled by the stepwise complexation reaction of a phenylazomethine dendrimer. Synthesis speed was found to be increased compared with the case without the dendrimer template. Hybridization for the Au25 superatom was also achieved using the complexation control of metal salts. View this paper
