顺磁性过渡金属（簇）桥连的富勒烯C60配位聚合物的合成及磁电性质研究

具有连续的π-d-π超共轭结构的顺磁性过渡金属（簇）桥连的富勒烯C60配位聚合物中，顺磁性过渡金属（簇）与C60分子间的电荷转移，不仅会影响金属的自旋电子状态，使其在特定条件下发生自旋交叉，而且会促进C60分子间电子的相互传输，在导电和磁性材料的制备中具有重要的研究价值。针对富勒烯C60过渡金属配位聚合物合成中难聚合和溶解性差等关键问题，本项目旨在以可以与C60实现多加成的顺磁性过渡金属（簇）为金属核心，通过探索辅助配位单元、还原剂、溶剂和有机阳离子等对聚合物的结构和性能的调控机制，优化合成方法，实现集导电性和磁性于一体的富勒烯C60与过渡金属（簇）的配位聚合物的合成；系统研究聚合物的电化学性质和磁学性质，阐明结构与性能之间的构效关系。本项目研究有望开发出一类新型的多功能分子器件材料，对推动富勒烯碳材料的应用性研究，具有重要意义。

Paramagnetic transition metal or metal cluster bridged fullerene C60 coordination polymer, with the fullerene and paramagnetic transition metal dual nature, in the preparation of conductive and magnetic materials has important research value. In order to meet the problem of difficult polymerization and poor solubility in the synthesis of fullerene C60 transition metal coordination polymers, the aim of this project is to use the paramagnetic transition metal or metal cluster which can be added with C60 as the metal core, explore the effect of auxiliary coordination units, reducing agents, solvents and organic cations on structure and properties of the polymer, optimize the reaction conditions, and obtain the coordination polymer of fullerene C60 with transition metal or metal cluster in combination with conductivity and magnetism. The electrochemical and magnetic properties of the polymer will be systematically studied to elucidate the structure-performance relationship. This study will not only develop a new type of multi-functional molecular device materials, but also promote the application of fullerene carbon material.
