摘要：

The temperature effect on the separation of fullerenes in LC was examined using monomeric type C-30, C-18 and C-8 alkyl bonded stationary phases. It appears that the C-30 phase exhibits superior separation ability for fullerenes. It is observed that the maximum retention temperature of fullerenes on the C-30 phase is around 20 degrees C. A strong correlation between the changes in NMR spectra and the retention behavior of the solutes was found. The interpretation of the retention behavior of fullerenes on the alkyl bonded stationary phases, including the behavior in subambient temperature, is discussed using the information obtained by CP-MAS solid-state NMR spectroscopy and LC.
