摘要： 利用直流电弧法,合成了含钙的富勒烯金属包合物.通过多步高效液相色谱（HPLC）法,首次分离出含钙的富勒烯金属包合物Ca@C88和Ca@C90 (I,II),用激光解析飞行时间质谱(MAL-DI-TOF MS)和紫外-可见-近红外（UV-Vis-NIR） 光谱进行了表征,并对其分子对称性和电子结构进行了讨论.

关键词: 富勒烯金属包合物, 钙, 吸收光谱

Abstract: Ca-containing Endohedral Metallofullerenes were synthesized by DC arc discharge method.C88 and C90-based group-2 metallofullerenes, Ca@C88 and Ca@C90 (I, II),were first isolated by multi-stage high-performance liquid chromatography (HPLC).All species were characterized by MAL-DI-TOF MS and UV-Vis-NIR absorption spectroscopy. Their electronic structure and possible molecular symmetries were discussed according to their retention times and absorption spectra.

Key words: Endohedral metallofullerenes, Calcium, Absorption spectrum
