英文摘要 | A method for "Sock-Ball" chromatographic separation of high molecular weight fullerenes is described. A prepared sock-shaped stationary phase (Sock-SAF-phase) was used for HPLC separation of several polycyclic aromatic hydrocarbons (PAHs) and fullerenes. Fullerenes, as ball- shaped molecules, are much more strongly retained than PAHs on this stationary phase and have the eluted order C□<C□<C□<C□<C□ the mobile phase of n-hexane/dichloromethane (100/0~80/20). In contrast, chromatography on the corre sponding unmodified silica phase or 8C-30H-phase (an intermediate phase of Sock-SAF-phase) gave no separation of fullerenes. This fact indicated that the separation of fullerenes on Sock-SAF-phase was related to the selective interaction with the sock moiety. |
