中文摘要: 金属冠醚在催化剂、液晶材料、阴离子识别试剂、磁性材料、生物活性等方面具有广泛的潜在应用价值, 而且还可作为"第二构筑单元"构筑一系列一维、二维和三维金属冠醚配位聚合物。本项目以羟肟酸为配体,分别与Mo, W, Ru, Rh, Ir和主族金属Ge、Sb、Bi等及其它过渡金属和稀土的盐在不同溶剂中反应,设计合成系列新型金属冠醚,进一步扩大金属冠醚的环金属在元素周期表中的数量,分别对它们的结构与磁性、气体吸附和分离等性质进行深入研究,得出其合成规律、结构特点、性质及结构-单分子磁体、气体吸附和分离等性质关系。既为该类配合物的合理设计提供思路,也为该领域的实际应用提供依据及信息。

英文摘要: Metallacrowns have wide applications in catalysis, liquid-crystal material, selective separation and recognition of anions, magnetic material, bioactivities. They can be also utilized as building blocks to construct 1D, 2D and 3D coordination polymers. We intend to design and synthesize a series of metallacrowns of Mo,W, Ru,Rh,Ir, Ge Sb, Bi, transition metals and lanthanides with hydroxamic acid ligands which extend the number of metallacrown ring metals in elemental periodic table and study their structures, gas absorptions and magnetic properties to find out their synthetical rules, properties and relationships between structures and Single-Molecule Magnet, gas adsorpion and separation properties. This project can not only provide thoughts for rationally devising metallacrowns but also provide bases and information for practical applications of this domains.
