摘　　要：对3种电化学方法合成的新型结构富勒烯衍生物进行了激光质谱表征,确认了1,2加成以及[5,6]开环富勒烯衍生物结构.质谱结果发现了富勒烯以及富勒烯衍生物与氧的结合峰,核磁共振结果进一步证明了富勒烯衍生物的结构,为含有C60结构衍生物的研究提供了有力的表征手段.Laser desorption/ionization time of flight mass spectrometry was used to characterize three fullerene derivatives,i.e.,1,2-dimethylbenzene C60,1,4-Dibenzyl-2,3-Benzamidine C60 and 2,3-Benzamidine C60.The structure of 1,2-adducts and two novel products with addition at ／ sites of C60 prepared from electrocatalytic reduction reactions was confirmed.Results of nuclear magnetic resonance further affirmed the structure of derivatives.The additive peaks of fullerene and their derivatives with oxygen were found.Laser desorption-ionization time of flight mass spectrometry provides a powerful technique for the characterization of new structural fullerene derivatives.
