中文摘要： 由于具有优良的分子磁学性质，TCNQ及其衍生物金属配合物受到了化学工作者的广泛关注。本项目拟通过调整取代基的种类（从供电子基到吸电子基）、个数（1，2和4）和改变反应溶剂等合成并结构表征多个系列TCNQ衍生物稀土配合物，研究其分子磁性，进而研究取代基、反应溶剂及稀土盐等对该类配合物的分子结构和分子磁性的影响，探索该类配合物的分子结构与分子磁性间的构效关系，尝试解释TCNQ衍生物自由基负离子与稀土离子间的磁相互作用机制。该项目的研究结果将为设计合成期望结构和优异磁性的TCNQ衍生物稀土配合物提供理论依据，具有重要的科学意义，同时可能提供具有潜在应用价值的分子磁性材料。

英文摘要： TCNQ and its derivative metal complexes have attracted chemical workers' considerable attention, because of their good molecular magnetic properties. In this project, we shall synthesize and structurally characterize several series of TCNQ derivative lanthanide complexes by adjusting the types (from electron-donating groups to electron-drawing groups) and numbers (1, 2 and 4) of substitution groups and changing the reaction solvents, as well as study their molecular magnetic properties. Further, we shall investigate the effects of substitution groups, reaction solvents and lanthanide salts on the molecular structures and magnetic properties of TCNQ derivative lanthanide complexes, explore the structure-property relationship, and try to explain the magnetic mechanism between TCNQ devivative radical anions and lanthanide ions. The results of this project shall provide theoretical basis for the design and synthesis of TCNQ derivative lanthanide complexes with the expected structures and excellent magnetic properties, possessing important scientific significance, and maybe provide the potential molecular magnetic materials.
