| Abstract: | The endohedral metallofullerene Tb 3N@C 80 was synthesized by using an improved DC arc 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 Tb 3N@C 80 . The technique of high pressure and high temperature extraction with DMF and two step HPLC method were used to extract and isolate small amounts of Tb 3N@C 80 . The sample was characterized by HPLC, MALDI TOF mass spectrum and UV Vis NIR spectrum. The observed isotope distribution is consistent with the expected isotope distribution for Tb 3N@C 80 , which shows that the sample obtained should be Tb 3N@C 80 . The UV Vis NIR spectrum shows a large difference between Tb 3N@C 80 and M@C 82 (M=Tb, Gd, La and so on). |
