High-yield and large-scale synthesis are highly demanded for the studies of gold nanoclusters. We developed a “cluster from cluster” approach to assemble gold nanoclusters with preformed atomically precise Au₁₃ precursors. This facile approach has proved to be very effective in the synthesis of the well-known magic cluster [Au₂₅(SR)₁₈]⁻, which could prepare the target cluster in high yield (overall yield up to ≈100 %) at large scale (gram-scale based on gold). This method can be applied in the synthesis of 10 Au₂₅ clusters with different R groups. This work presents an important approach that may be extended to high-yield and large-scale synthesis of other metal nanoclusters.

簇中簇：神奇金纳米簇的定量方法 [Au25(SR)18]−

金纳米团簇的研究非常需要高产率和大规模合成。我们开发了一种“簇中簇”的方法，用预先形成的原子级精确的Au ₁₃前体组装金纳米簇。事实证明，这种简便的方法在合成著名的魔法簇 [Au ₂₅ (SR) ₁₈ ] ^{- 时}非常有效，可以大规模制备高产率（总产率高达 ≈100 %）的目标簇（基于黄金的克级）。该方法可用于合成具有不同R基团的10个Au ₂₅簇。这项工作提出了一种重要的方法，可以扩展到其他金属纳米团簇的高产率和大规模合成。
