光致发光过渡金属配合物的设计及光化学研究

Abstract d10 complexes have become an active explored area for the versatility of their coordination geometries, biological or medicinal activities and intriguing spectroscopic properties. Four series of Cu(I), Ag(I) and Au(I) photoluminescent complexes have been designed and synthesized in this project. They are phosphine-heterocyclic nitrogen compounds mix-ligand complexes, 2,6-bis(diphenylphosphino)pyridine complexes, 1,4-bis(diphenylphosphino)benzene complexes and CuSCN-(heterocyclic nitrogen compounds) coordination polymers. The structures of the complexes have been characterized by X-ray crystallography. Most Cu(I) complexes are four-coordinated and few of them are three- or five-coordinated. The Ag(I) and Au(I) complexes are two- or three-coordinated. The spectroscopic properties of the complexes have been studied. The luminescent excited states were ascribed to be MLCT (metal-ligand charge transfer) or IL (intraligand) in nature.

本项目选择和合成合理的有机物如膦或杂环分子等单齿或多齿配体，与过渡金属离子形成配位化合物，通过系统地研究其组成、结构和光物理光化学，设计筛选出具有光致发光性能的配合物，考察金属离子、配体以及配合物结构对光致发光性能的影响。进一步研究配合物的光化学反应，为发展具有特殊功能的光化学器件打下理论和应用基础。
