摘要
新型富勒烯衍生物的合成及其性质研究一直是富勒烯化学的热门课题之一。合成新型具有特殊光、电性能的富勒烯衍生物,对拓展富勒烯基新材料具有重要意义和作用。利用1,3-偶极环加成反应(Prato反应),成功地将强吸电子基团五氟苯基接到C60碳笼上,研究了反应条件对单加成产物的影响,合成了N-甲基-2-五氟苯基-3,4-富勒烯基吡咯烷。产物经氢核磁共振谱、氟核磁共振谱、紫外-可见吸收光谱、红外吸收光谱和质谱表征确证。并利用液-液界面沉积法(LLIP法)制备了该衍生物的方片状纳米薄片,为研究其光电性能奠定了基础。
The study on the synthesis and properties of new types of fullerene derivatives has been one of the hot topics in the fullerene chemistry.The synthesis of fullerene derivatives with unique photoelectric properties will play an important role in exploring novel fullerenes-based materials.N-methyl2-pentafluorophenyl-3,4-full--eropyrrolidine containing strong electron-accepted group pentafluorophenyl is successfully synthesized by 1,3-dipolar cycloaddition reaction,which is characterized by 1H-NMR,19F NMR,UV-vis IR spectroscopy and MS.Besides,the effect of reaction conditions on the production of [60] fullerene monoadduct is studied.The nanosheets of C60 derivatives are obtained here by the LLIP method,which lays a foundation for studying the photoelectric properties of novel fullerene derivatives.
