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.
