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.
