| 摘 要： | 采用直流电弧法, 以掺有金属合金和B4C粉末的光谱纯石墨棒作为阳极, 在He和NH3混合气氛中进行电弧放电, 首次高产率合成了一系列Gd2@C2n(94≤2n≤142)的大分子双金属富勒烯包合物. 实验证明, 异相物质作为热的载体并同时催化产生了大分子富勒烯金属包合物, 而NH3则抑制了C60和C70等其它富勒烯的生成.

| Abstract: | By the DC arc-discharge of graphite rods doped with other substances in He and NH3 mixing gas,higher endohedral metallofullerenes(EMFs) were synthesized in a high yield. This lays the foundation for the separation,purification and further study of higher EMFs. The doped materials act as heat carriers and at the same time catalyze the growth of higher EMFs,whereas NH3 suppresses the formation of fullerenes such as C60 and C70,etc. |
