Abstract A method for “Sock‐Bail” 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 50 < C 70 < C 76 < C 78 < C 84 in the mobile phase of n ‐hexane/dichloromethane (100/0 ∼ 80/20). In contrast, chromatography on the corresponding unmodified silica phase or SC‐3OH‐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.
