中文摘要： 富勒烯作为一种新型纳米碳材料，由于其独特的结构和性质，显示了极为广阔的应用前景。而富勒烯的衍生化是实现富勒烯应用的关键。采用控制电位电解合成富勒烯的衍生物（包括富勒醇、羧基衍生物和胺基衍生物），考察衍生物的电化学性质，制备富勒烯衍生物电还原产物的化学修饰电极，研究其对析氢反应的电催化。探索加成基团的种类和数目对电催化析氢性能的影响。目前有关这方面的研究仅有我们之前的一篇报道，具有很强的创新性。同时研究这些水溶性的富勒烯衍生物与生物分子的相互作用，构建电化学传感器。这方面的研究不仅有助于探索富勒烯衍生化的新方法，了解这类纳米材料的电化学性质，为构建电催化和传感界面的研究提供理论依据，为其在能源转化和传感领域的应用奠定基础，是一个具有理论和实用意义的新课题。同时也为当前化学领域的研究热点之一:碳基材料的合成和应用研究打下基础，是一项开拓性的研究，具有十分重要的理论意义和研究价值。

英文摘要： As a kind of novel carbon nanomaterials, fullerenes have demonstrated widely applicable prospects due to their peculiar structures and properties. The key to realize the application of fullerenes is fullerene derivatization. In this project, fullerene derivatives including fullerenols, fullerene carboxylate derivatives and fullerene amine derivatives will be synthesized by controlled-potential electrolysis and their electrochemical properties will be investigated. The electrodes modified with electrodeposited products of fullerene derivatives will be prepared and electrocatalysis for hydrogen evolution reaction (HER) at these modified electrodes will be explored. Effects of kinds and numbers of various addition groups on electrocatalytic performance of HER will be studied. The work is novel because so far only one paper has been reported about this by our group. In the mean time, interaction between the synthesized fullerene derivatives and biomolecules will be studied to construct electrochemical sensors. Not only the study is helpful in exploring the new methods of fullerene derivatization, understanding the electrochemical properties of these new nanomaterials is helpful to provide the theory basis for construction of electrocatalytic and sensing interfaces; but also the study founds a base for their applications in the fields of energy conversion and sensing. The project is one new task with theoretical and practical significance. In the mean time, the study also lays a foundation for one of hot topics in current chemistry research field: synthesis and applications of the carbon-based material. The project is an initiative research, and it has extremely important theoretical significance and research value.
