Research Progress of Silver Chalcogenide Clusters Constructed by Tert-Butyl Mercaptan Ligand

高核银簇化合物因其有趣的电子结构和多样的几何结构受到了广泛关注。根据Lewis酸碱理论和配位化学理论,银离子作为提供空轨道的酸性中心,常与作为碱性中心的携带孤对电子的有机配体结合形成稳定的配位化合物。炔基、硫醇、有机膦配体已被广泛应用于与银离子配位,从而形成各种结构的银簇化合物。介绍了本课题组用叔丁基硫醇配体构筑的硫属银簇的研究进展,以及不同构型硫属银簇的合成方法及其结构,对其潜在的发光和电化学等性质进行了探究,并对硫属银簇的应用前景和发展方向进行了展望。

High-nuclear silver clusters have recently received increasing attention owing to their interesting electronic structures and diverse geometric structures. According to Lewis acid-base theory and coordination chemistry theory, silver ions, as acidic centers that provide empty orbitals, often combine with organic ligands that carry lone pairs of electrons as basic centers to form stable coordination compounds. Alkynyl, thiol, and organic phosphine ligands have been widely used to coordinate with silver(I)ions to form silver clusters with various structures. This paper introduced the research progress of the silver chalcogenide clusters constructed by tert-butyl mercaptan ligand, as well as the synthesis methods and structures of silver chalcogenide clusters with different configurations, and explored its potential luminescence and electrochemical properties. The application prospects and development directions of silver chalcogenide clusters was prospected.
