Discrete supertetrahedral Tn chalcogenido clusters, which can be regarded as the smallest semiconductor quantum dots with precise chemical composition, have attracted considerable attention due to their outstanding photoluminescent, photoelectric, and photo/electrocatalytic properties. Such discrete molecular clusters are suitable for solution processing towards functional materials and can be used as precursors for constructing open‐framework chalcogenides. Traditionally they were synthesized hydro(solvo)thermally with molecular solvents (e. g. water or organic amines), while until recently imidazolium‐based ionic liquids (ILs) were found suitable for their preparation acting as reactive solvent and stabilizer for molecular clusters. We discuss herein recent advances in the syntheses, crystal structures, and selected properties of discrete supertetrahedral Tn chalcogenido clusters obtained in ILs. In particular, the enhanced photocatalytic properties of monodispersed Tn clusters in solvents are highlighted.

离子液体中合成的离散超四面体Tn硫属元素簇：晶体结构和光催化活性

离散超四面体T n硫属元素簇，由于其出色的光致发光，光电和光/电催化性能，可以被视为具有精确化学成分的最小半导体量子点，引起了相当大的关注。这种离散的分子簇适合用于功能材料的溶液加工，并且可用作构建开放框架硫族化物的前体。传统上，它们是使用分子溶剂（例如水或有机胺）通过热（水）热合成的，而直到最近才发现基于咪唑鎓的离子液体（IL）适合用作分子簇的反应性溶剂和稳定剂。我们在此讨论离散超四面体T的合成，晶体结构和选定性质的最新进展在IL中获得n个硫属元素簇。特别地，突出了在溶剂中单分散的T n团簇的增强的光催化性能。
