Assembly and Metal Complex Properties of Terpyridine Ligands

金属-配体间的配位作用是超分子化学中最重要的相互作用之一,寡聚吡啶配体可以与许多过渡金属离子配位,形成具有独特磁、光物理和电化学性质的过渡金属配合物,因此联三吡啶配体过渡金属配合物性能研究引起化学家的广泛关注。本文系统综述了联三吡啶配体及其衍生物的组装策略及其过渡金属配合物的光化学与光物理性能,包括单极、二极及多极配体以及由这类配体组装得到的各种拓扑结构的单核、多核过渡金属配合物,如线型金属寡聚物、金属聚合物、金属大环化合物、有机金属树枝状化合物等,并介绍这些配合物在该领域研究和应用前景。

Metal-ligand coordination is one of the most important interactions used in supramolecular chemistry. Oligopyridine ligands can coordinate with many transition metal ions and form stable complexes with unique magnetic, photophysical and electrochemical properties, so transition metal complexes based on terpyridine ligands have been attracting considerable attention. This review systematically summarizes the assembly methodologies for terpyridine ligand and its derivatives and the photophysical and photochemical properties of terpyridine transition metal complexes, monotopic, structures, including ditopic and multitopic terpyridine ligands and mononuclear, multinuclear complexes with various topologic such as linear metal oligomers, dendrimers. Meanwhile, the perspectives in their metallopolymers, applications and metallomacrocyclic compounds and organic-metal studies are also emphasized.
