Practical approaches to the synthesis of atomically precise metal nanoclusters are in high demand as they provide the structural basis for investigating nanomaterials’ structure–property correlations with atomic precision. The Brust–Schiffrin method has been widely used, while the essential reductive ligands (e.g., thiols) limit the application of this method for synthesizing metal nanoclusters with specific frameworks and surface ligands. In this work, we developed a photochemical route for synthesizing atomically precise metal nanoclusters by applying disulfide, which is a widely available, stable, and environmentally friendly sulfur source. This method enables the construction of structurally diverse metal nanoclusters and especially features the synthesis of PhS-protected metal nanoclusters that were not easily achieved previously and the gram-scale synthesis. A reduction–oxidation cascade mechanism has been revealed for the photochemical route. This work is expected to open up new opportunities for metal nanocluster synthesis and will contribute to the practical applications of this kind of nanomaterial.

从二硫化物合成原子级精确金属纳米团簇的光化学路线

人们对合成原子级精确金属纳米团簇的实用方法有着很高的需求，因为它们为研究纳米材料的结构-性能与原子级精度的相关性提供了结构基础。Brust-Schiffrin方法已被广泛使用，但必需的还原配体（例如硫醇）限制了该方法在合成具有特定骨架和表面配体的金属纳米团簇中的应用。在这项工作中，我们开发了一种利用二硫化物合成原子级精确金属纳米团簇的光化学路线，二硫化物是一种广泛使用、稳定且环保的硫源。该方法能够构建结构多样的金属纳米团簇，特别是以前不易实现的PhS保护的金属纳米团簇的合成以及克级合成。光化学途径的还原-氧化级联机制已被揭示。这项工作有望为金属纳米团簇的合成开辟新的机遇，并将有助于此类纳米材料的实际应用。
