硫代保护的金属纳米团簇(或称硫代金属纳米碳化物)由于其良好的分子结构和有趣的分子性质而成为一类很有前途的功能材料。由于金属纳米管具有良好的生物相容性和良好的光致发光性能，近年来纳米管领域的研究进展一直致力于探索金属纳米管作为生物医学领域的新型发光材料。从根本上讲，该领域的最新进展也着眼于解决金属纳米管发光性质的基本方面，为开发高效的制备高发光金属纳米管的策略提供了一些启示。在这个视角下，我们讨论了最近发现的聚集诱导发射(AIE)现象的物理化学，并展示了AIE对于理解硫化金属纳米管的发光性质的重要意义。然后，我们探索了具有AIE特性的硫代化金属纳米管独特的物理化学性质，并重点介绍了合成AIE型发光金属纳米管的一些最新进展。最后讨论了ME型发光金属纳米管的发展前景和方向。
Thiolate-protected metal nanoclusters (or thiolated metal NCs) have recently emerged as a promising class of functional materials because of their well-defined molecular structures and intriguing molecular-like properties. Recent developments in the NC field have aimed at exploring metal NCs as novel luminescent materials in the biomedical field because of their inherent biocompatibility and good photoluminescence (PL) properties. From the fundamental perspective, recent advances in the field have also aimed at addressing the fundamental aspects of PL properties of metal NCs, shedding some light on developing efficient strategies to prepare highly luminescent metal NCs. In this Perspective, we discuss the physical chemistry of a recently discovered aggregation-induced emission (AIE) phenomenon and show the significance of AIE in understanding the PL properties of thiolated metal NCs. We then explore the unique physicochemical properties of thiolated metal NCs with AIE characteristics and highlight some recent developments in synthesizing the AIE-type luminescent metal NCs. We finally discuss perspectives and directions for future development of the ME-type luminescent metal NCs.
