摘要： 在利用电弧放电法合成铽的富勒烯笼内金属包合物时,首次观察到Tb3N@C80的存在,并用两步HPLC法将其分离和提纯.进一步的实验结果表明,氮气的加入是导致Tb3N@C80生成的原因.并用MALDI-TOF-MS和UV-Vis-NIR光谱对其进行了表征.

Abstract: The endohedral metallofullerene Tb3N@C80 was synthesized by using an improved DCarc discharge method under a He atmosphere containing 2%～5% nitrogen. The experimental results indicated that the introduction of small amounts of nitrogen into the electric arc reactor led to the production of Tb3N@C80. The technique of high pressure and high temperature extraction with DMFand two step HPLCmethod were used to extract and isolate small amounts of Tb3N@C80. The sample was characterized by HPLC, MALDI TOFmass spectrum and UV-Vis-NIRspectrum. The observed isotope distribution is consistent with the expected isotope distribution for Tb3N@C80, which shows that the sample obtained should be Tb3N@C80. The UV-Vis-NIRspectrum shows a large difference between Tb3N@C80 and M@C82 (M=Tb, Gd, La and so on).

Key words: Endohedral metallofullerene, Tb3N@C80, Mass spectrum, UV-Vis-NIR spectrum
