中文摘要： 与空心富勒烯相比，金属富勒烯由于兼具金属元素与碳材料的性质而备受关注，在生物医学、光电子器件、磁性材料等方面有很多应用。从应用角度来看，将金属富勒烯衍生化是实现其应用的必经之路，而将金属富勒烯或其衍生物组装成形貌、尺寸均一的微纳结构，可以更大程度地拓展其应用范围，并有可能发现一些新性质。但目前只是针对空心富勒烯的微纳结构开展了一些初步的研究，而对于金属富勒烯的研究几乎是一片空白。本项目拟选用多种具有不同碳笼结构和内包金属团簇的物种，尤其是目前可量化生产的单金属富勒烯M@C82和三金属氮化物富勒烯M3N@C80及其衍生物开展研究，采用多种方法制备不同形貌的微纳结构，如纳米片、棒、管等。在此基础上，考察碳笼大小、外接基团性质及内包金属物种对形貌的影响，以期获得一般性规律。最后制备出相应的微纳器件，研究各种不同微纳结构的物理化学性质，主要着眼于光电转换性能，以考察结构与性质的关系。

英文摘要： Distinctly different from empty fullerenes,endohedral metallofullerenes (EMFs) have unique structures and novel propeties bacasue of the presence of metallic species and strong metal-carbon interactions. From the point view of chemistry, derivatization of EMFs is the best way to make them useful in many fields like biomedicine, photovoltaics, electronics and magnetics. Meanwhile, construction of micro/nano-meter sized materials based on EMFs and their derivatives with uniform structure and morphopogy is even more meaningful because such materials may bear unprecedented properties and novel applciations.Although preliminary results of some typical nano structures based on empty fullerenes have been reported, correspoding results relating to EMFs are really rare. In this project, we focus on a variety of EMF species with different cage size (structure) and different metallic species, especially these readily availible compounds such as M@C82 and M3N@C2n.Sovelnt-based methods such as the liquid-liquid interfacial precipitation method will be utilized to creat many different nano structures such as hexagonal plate, nanorod and nanotube.On this basis, we will investigate the influences of the cage structures and the types of internal metallic species on the morphology of the mciro/nano structures, trying to get some general rules governing the formation process of the nano structures. Finally, we will study the electronic, optical and magnetic properties of these nano structures by creation of corresponding devices.
