| 摘 要： | 给出了用阳极电弧在氦气氛下蒸发含镧石墨棒高效制备宏观量C60的内含镧原子的衍生物La@C60及在常温常压下以铁粉为催化剂高效制备C60的外修饰衍生物C60Br24的方法，还给出了C60Br24的红外吸收谱、C60,C69和La@C60混合物的质谱、13C核磁共振谱等波谱性质。经红外谱分析，产物为单一结构的C60Br24分子，而非混合物。核磁共振谱、质谱、液相色谱分析表明，镧原子被囚于C60内，但并未引起C60分子笼体的膨胀、缩小及变形。

| Abstract: | La@C 60 is prepared in gram quantities using anode arc vaporization of graphite rod with purity lanthanum powder wick in atmosphere of helium.C 60 Br 24 is prepared by mixing purity of C 60 powder with neat bromine and iron powder catalyst at ambient temperature.The spectral characterizations of C 60 Br 24 and the mixture of C 60 ,C 70 and La@C 60 ,such as FTIR,MS, 13 C NMR and HPLC are also presented in this paper.The IR spectrum indicated that the product is much more C 60 Br 24 rather than the mixture of brominated fullerites.The spectra of MS, 13 C NMR and HPLC indicated that the lanthanum atom is trapped in the C 60 cage and didn't cause the cage to expand,reduce or deform. |
