不同Gd∶C比对金属富勒烯生成的影响及其质谱研究

The Difference Gd∶C to the Results of Metallofullerenes Formation and MS Study

研究了不同 Gd∶ C比对金属富勒烯生成的影响 ,结果表明 :随着 Gd∶ C比例大小不同 ,对金属富勒烯生成结果的影响也不同。通过激光解析飞行时间质谱 (LD- TOFMS)和电喷雾质谱 (ESI- MS)分析了提取液的富勒烯组成 ,得到当 Gd∶ C为 1∶ 5 0时 ,金属富勒烯有最高产率。

The difference Gd∶C to the results of metallofullerenes formation is studied.It is found when Gd∶C is 1∶50,it will have the best results to synthesis of metallofullerenes Gd@C 82 ,Gd 2@C 80 .Metallofullerenes were synthesized by using alloys as metal source in the arc-discharging method.LD-TOF and ESI mass spectrometry were used to characterize the toluene soxhelting and pyridine high temperature high pressure extracts.
