紫外光氧化法制备水溶性富勒醇

富勒烯因其特殊的结构在生物学中具有潜在的重要应用价值,而其不溶于水阻碍了其在相关领域的进一步应用。制备水溶性的富勒烯衍生物的方法被证实是一种可行的途径。本文采用波长为254nm的紫外光作为照射源,通过照射水溶液中的H2O2使其分解产生·OH自由基,并与富勒烯分子发生加成反应,成功制备了富勒醇。对制备的富勒醇进行了纯化、分析和表征。实验结果表明,合成的富勒醇分子结构式为C60(OH)26。紫外光氧化法制备水溶性富勒醇是一种简单可行的新方法,为由富勒烯制备富勒醇提供了新的借鉴。

Preparation of fullerenol from fullerene by use of UV light oxidation

Fullerene holds a potentially important application value in biology for its special structure.However,its indissolubility in water limits its further application in relative fields.Preparation of water-soluble fullerene derivatives has been proved to be an effective way to solve the problem.In this paper,UV light with 254nm wavelength Was used as the irradiation source.Fuilerene molecules Can be attacked by hydroxyl radicals(·OH)produced from photo-decomposition of hydrogen peroxide(H_2O_2)via subsequent additive reaction.Then fullerenol was successfully synthesized and its structure was characterized by FT-IR,1H-NMR and UV-vis.The experimental results show that the molecular structure of fullerenol is C_(60)(OH)_(26).It may be a novel method to synthesize water-soluble fullerenol easily by the UV oxidation.
