The silylation of endohedral mono-metallofullerenes (Y@C(82) and La@C(82)) and isolation of the corresponding adducts by HPLC separation have been accomplished. The redox properties of the silylated mono-metallofullerene were first clarified by CV and DPV measurements, indicating that the bis-silylated mono-metallofullerenes have lower oxidation and higher reduction potentials than the parent mono-metallofullerenes. These results reveal that bis-silylation is very effective for producing the electronegatively mono-metallofullerene derivatives as well as empty fullerenes.
内嵌金属富勒烯（Y@C(82)和La@C(82)）的硅烷化反应以及通过高效液相色谱分离法分离相应加合物的工作已经完成。通过循环伏安法（CV）和差分脉冲伏安法（DPV）测量首次阐明了硅烷化单金属富勒烯的氧化还原性质，结果表明，双硅烷化单金属富勒烯比母体单金属富勒烯具有更低的氧化电位和更高的还原电位。这些结果表明，双硅烷化对于制备带负电的单金属富勒烯衍生物以及空心富勒烯非常有效。
