摘要
Sm@C 82 (Ⅲ) was effectively extracted by the high temperature DMF extraction and separated in one step HPLC, making the further studies of its properties possible. The successful purification of Sm metallofullerene with such a low yield indicates that the high temperature DMF extraction is much effective. The cyclic and differential pulse voltammgrams of the pure Sm@C 82 (Ⅲ) were first measured, indicating that it has a good electron accepted ability. Up to 6 electrons can be added to them. The analysis of the potentials, the potential differential and the number of electron transferred show that Sm prefers to take +2 charge state in the carbon cage. The study of electronic structure would help us to produce, extract more metallofullerenes and synthesize useful materials.
