Abstract

The separation of fullerenes with monomeric and polymeric octadecylsilica (ODS) bonded phases has been studied and the existence of three C₇₈ isomers confirmed. It has been found that the elution order of higher fullerenes is controlled by their molecular size and shape and that polymeric ODS resolves three C₇₈ isomers, one being eluted faster than C₇₆. Monomeric ODS cannot resolve two of the C₇₈ isomers, although a lower column temperature of 10 °C gives its partial separation. UV-visible spectral assignments were confirmed by FAB-MS measurements of the fractionated samples.
