Ca@C88和Ca@C90的合成、分离和表征
Preparation, Isolation and Characterization of Ca@C88 and Ca@C90
【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@c99(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.
【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.
