Ligand-protected metal nanoclusters as unique nanomaterials have attracted great attention. The protecting ligands that directly bind on the cluster surfaces are crucial in dictating the structures and properties of the clusters. In contrast to the extensively studied thiolates, alkynyl ligands have been found recently to be important ligands for passivating gold/silver cluster surfaces. In this Frontier article, recent advances in alkynyl-protected metal nanoclusters are overviewed, and the structures, luminescence and catalytic activities are also discussed. It is demonstrated that alkynyls are very promising ligands in the control of the structures and properties of gold/silver nanoclusters.
配体保护的金属纳米团簇作为独特的纳米材料已引起了极大关注。直接结合在团簇表面的保护配体对于决定团簇的结构和性质至关重要。与已被广泛研究的硫醇盐不同，炔基配体最近被发现是用于钝化金/银团簇表面的重要配体。在这篇前沿文章中，综述了炔基保护的金属纳米团簇的最新进展，并讨论了其结构、发光和催化活性。结果表明，炔基在控制金/银纳米团簇的结构和性质方面是非常有前景的配体。
