中文摘要： 稀土近红外发光材料在光纤通讯、激光、荧光免疫分析等方面有重要应用价值。本项目拟采用含多联吡啶和-C≡C-官能团、具有平面大共轭体系的双功能共轭有机化合物为桥联配体，分别与过渡金属簇和稀土发光配合物反应，逐步组装出系列过渡金属同核、异核簇共轭桥联的稀土近红外发光配合物；或采用Sonogashira和Cadiot-Chodkiewicz偶联反应，将含特定官能团的过渡金属簇模块与稀土发光中心模块组装成目标配合物，探索该类化合物的近红外发光性能和能量传递机制。通过对金属种类和配体的调控，研究其结构与近红外发光性能的关系，阐明过渡金属-金属键、混和金属的存在，及稀土金属f电子与过渡金属簇单元间的电子相互作用对稀土中心近红外发光效率与寿命的影响，建立新的近红外发光体系，拓宽金属原子簇化学的研究。为内蒙古自治区过渡金属与稀土资源的高值化利用做出应有的贡献。

英文摘要： Near-infrared luminescence lanthanide complexes have important application value in the areas of fiber-optic communication, fluorescent immunoassay, medicine and materials science. In this project, we are going to 1) assemble the transiton metal homo- and hetero-nuclear cluster conjugate linked near infrared luminescence lanthanide complexes by reaction the bi-functional conjugated organic compounds containing polypyridyl and -C≡C- group with transiton metal clusters and luminescence lanthanide complexes step by step, or reaction the transition metal cluster containing special groups with luminescence lanthanide compounds according to the methods of Sonogashira and Cadiot-Chodkiewicz coupling reaction. 2) investigate the relation between the target complexes's structure and the properties of near-infrared luminescence by regulating and controlling the sorts of metal and organic ligands.3) elucidate the effect of metal-metal bonds, mixed metal, and the electron-electron intereaction between the f electrons of lanthanide center and the transition metal cluster unit on the efficiency and lifetime of near-infrared luminescence. 4) build a new near-infrared luminescence system and broaden the study field of the transition metal cluster chemistry. Furthermore, contribute to the application of the transition metal and
