| 摘 要： | 本文全面综述了多种60]富勒烯衍生物的结构,阐述了(13)~C NMR谱在60]富勒烯衍生物结构表征中的应用,重点讨论了不同对称性60]富勒烯衍生物的(13)~C NMR谱图特征.通过60]富勒烯部分(13)~C共振线的化学位移、数目和相对强度,可以确定60]富勒烯衍生物的对称结构和加成方式.对于C_s、C_(2v)和C_(3v)对称性的60]富勒烯衍生物,镜面上的碳原子的相对化学位移很大程度上取决于他们距加成位置的距离.因此,(13)~C NMR谱在碳笼具体结构的确定中具有不可替代的作用.

| Abstract: | The structure of all kinds of 60]fullerene derivatives and their characterization via (13)~C NMR spectros-copy are reviewed and the (13)~C NMR spectroscopic properties of various symmetry 60]fullerene derivatives are mainly dis-cussed . From the chemical shifts, the number and the relative intensity of resonances for 60]fullerene moiety, symmetry and addition pattern of 60]fullerene derivatives can be confirmed. For the C_s, C_(2v) and C_(3v) symmetry 60]fullerene de-rivatives , the relative chemical shift of the carbon atoms on the mirror planes depends greatly upon their distance from ad-dition position on the surface of 60]fullerene. So (13)~C NMR spectroscopy plays the important role in identification of the particular structure of 60]fullerene cage. |
