Progress in Chain-Like Molecules with Metal-Metal Bonds in Backbone

以金属-金属键为骨架的链状分子,具有离域的σ电子,由于其特殊的光、电、磁及催化性能,引起了科学家们的广泛关注。本文根据金属-金属成键的方式,对近年来报道的金属链状分子进行了综述。文中总结了三大类型的金属链状分子:金属聚合物聚锡和聚锗、非配体桥连的过渡金属-金属键骨架链状分子以及多吡啶胺配体支撑的多核过渡金属-金属键骨架链状分子。最后对金属-金属键骨架链状分子结构进行了展望,为设计新型功能分子材料提供了思路。

Molecules containing metal-metal bonds in backbone with delocalization of σ electrons between metal atoms have fascinated scientists because of their special optical,electrical,magnetic and catalytic properties. Herein advances in the preparation of chain-like molecules containing metal-metal bonding units in backbone were reviewed.Three types of chain-like molecules with metal-metal bonding including polystannes and polygermanes,molecules with non-ligand bridged transition metal-metal bonding backbone,as well as molecules with polypyridylamine ligand supported metal-metal bonding backbone are introduced. Finally,an overview of metal-metal bonding chain-like molecules to provide ideas for the design of new functional molecular materials was presented.
