【Abstract】 A series of Fullerenes and their derivatives were prepared, and characterized using several techniques of mass spectrometry. Their stability and the low fragmentation under the conditions of mass spectrometry were revealed. The Fullerenes and their derivatives give out high intensity molecular ion peaks and small fragment peaks. It has been suggested that the field ionization mass spectrometry and liquid second ion mass spectrometry techniques are good method for the qualitative analysis of Fullerenes and their derivatives, and can possibly be used for the quantitative analysis of these compounds.更多还原
