多金属氧酸盐复合材料因其在催化、磁性、光学等领域的应用前景备受关注，目前还没有关于有机金属和稀土共嵌入的多金属氧酸盐复合材料的报道。本项目拟利用以简单起始反应原料在有机增溶剂作用下进行一步自组装策略和微波加热条件下杂多钨氧酸盐前驱体与有机金属基团、稀土离子和氮杂环有机多羧酸配体分步引入的反应策略来合成有机金属与稀土共嵌入的含亚族价杂原子多钨氧酸盐有机−无机复合材料，系统研究目标复合材料可见及近红外发光性能、发光效率、寿命衰减行为、发光动力学、多组分之间能量传递现象和发光机理，考察温度、有机金属基团或氮杂环有机多羧酸配体对发光性能和寿命衰减行为的影响。发现发光颜色可调和上转换发光行为的复合材料。对目标复合材料的磁性进行深入调查，发现特殊的磁性现象，探讨结构和磁性间的联系，阐明磁性产生机理。该项研究为实现有机金属与稀土共嵌入的多钨氧酸盐复合材料在发光和磁性方面的开发与应用奠定基础。

Polyoxometalate composite materials have attracted increasing interest because of potential applications in catalysis, magnetism and optics, etc, however, to date, there is no report on organometal and rare-earth encapsulated polyoxometalate composite materials. In this project, we will utilize the one-step assembly strategy of the simple starting materials in the presence of organic solubilizers in the reaction system and the step by step strategy of the stepwise introduction of heteropolyoxotungstate precursors, organometal groups, rare-earth ions and nitrogen heterocyclic organic carboxylic acid ligands to the reaction system under the condition of microwave heating to prepare organometal and rare-earth encapsulated subvalence-heteroatom containing polyoxotungstate organic-inorganic composite materials, systematically investigate the visible and NIR luminescence properties, luminous efficiency, lifetime decay behaviors, luminescence kinetics and energy transfer phenomena within different components and luminous mechanisms of target compound materials and study the effects of temperature, organometal groups and nitrogen heterocyclic organic carboxylic acid ligands on luminescence properties and lifetime decay behaviors. We also try to find eimission-color-tunable or up-conversion luminescence behavior target compound materials. Furthermore, we will intensively probe the magnetic properties of target compound materials, discover special magnetic phenomena, explore the relations between structure and magnetism and illustrate magnetic mechanisms. Therefore, this study will lay the foundation for realizing the developments and applications of organometal and rare-earth encapsulated polyoxotungstate composite materials in light and magnetic fields.
