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
