清华大学王泉明团队开发了从团簇到团簇制备神奇金纳米团簇[Au25（SR）18]的定量方法。 相关研究成果于2021年4月8日发表在《德国应用化学》。

金纳米团簇的高收率和大规模合成是其研究的迫切需求。

研究人员开发了一种“从团簇到团簇”的方法来组装金纳米团簇和原子级精度的Au 13前驱体。该简便的方法在合成众所周知的神奇团簇[Au 25（SR）18]方面非常有效，它可以大规模（以金为基础的克级）制备高产率（总产率高达~100%）的目标团簇。该方法可用于不同R基团的10个Au-25团簇的合成。

该工作为其它金属纳米团簇的高收率和大规模合成提供了一条重要途径。

Abstract: 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 Au  13  precursors. This facile approach has proved to be very effective in the synthesis of the well‐known magic cluster  [Au  25  (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  Au  25  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.
