摘要： 采用对掺入La2O3的石墨棒原位活化并结合交换电极回放方法制备了产率较高的金属富勒烯,并用甲苯高温热提取的方法有效地提取出La@C2n,其中La@C74为可溶性金属富勒烯增加了新成员。同时,首次采用解吸电子轰击质谱对提取物进行了表征,讨论了提取物的ESR谱。

Abstract: The synthesis for lanthanofullerenes was studied by activating the La2Oa containing graphite rod in situ and back-burning the carbide-rich cathode deposite, La@C2n are efficiently extracted in high temperature toluene, among them, La@C74 as a new species is added into the soluble lanthanofullerenes, The toluene extraction is first characterized by desorption electron impact(DEI)mass spectrometry, The ESRspectrum of the extraction at room temperature is also discussed.

Key words: Lanthanofullerenes La@C2n, High temperature toluene extraction, DEI MS, ESR spectrum
