利用N-甲基甘氨酸、2,4-二硝基苯甲醛和C60反应,合成分离出了含有两个硝基的新型富勒烯吡咯烷衍生物1,并对其工艺条件进行了研究,探讨了反应物剂量比、温度和时间对产物1产率的影响,得到了合成产物1的最佳工艺条件:反应物剂量比为1:2:6、温度为95℃、反应时间为40h,此时产物1产率可达到65.8%(以消耗的C60计)。同时用^1H NMR、FT-IR、MS、UV-Vis等光谱手段确定了产物1的分子结构。
A new fullerene derivative 1 which contains energy-producing groups was prepared by the Prato reaction,and the reaction conditions affecting the yield of product 1 were investigated. The optimized reaction conditions which afforded 65.8% (based on consumed C60) of product 1 are:molar ratio of C60, 2,4-dinitrobenzaldehyde and N-methylglycine 1 : 2 : 6, reaction temperature 95℃, reaction time 40 h. The structure of product 1 was characterized by UV-vis,FT-IR,^1H NMR and MS. Further study on the property and application of 1 is under way.
