摘要: 在常温、Ar气保护下研究了金属富勒烯与哌嗪(Piperazine)的反应, 并用硅胶柱分离了3种金属富勒烯衍生物. 用激光解析飞行时间质谱、紫外-可见-近红外光谱和傅里叶变换红外光谱等手段分析确定其结构分别为La@C82-C4N2H8, La@C82-C4N2H8-H8和La@C82-(C4N2H8)2-H6. 对比C60与哌嗪的反应结果发现, 与空富勒烯相比, 金属富勒烯反应活性更高, 产物加成数目更多.

Abstract: Metallofullerene derivatives offer the opportunity to produce novel and advanced materials. In this work, we presented the synthesis of metallofullerene piperazine derivatives under different conditions by changing the temperature, light and ratio of the reactants. Three metallofullerene piperazine derivatives [La@C82-C4N2H8, La@C82-C4N2H8-H8, and La@C82-(C4N2H8)2-H6] were separated and confirmed by MALDI-TOF-MS, UV-Vis-NIR and FTIR. Compared with the hollow fullerene C60, we found that metallofullerene showed higher reactivity than C60 and produced different derivatives. The mechanism of the reaction was discussed.
