Separation of C₆₀ and C₇₀ fullerenes on methoxyphenylpropyl bonded stationary phases in microcolumn liquid chromatography

Abstract

Abstract Chromatographic separation of C 60 and C 70 fullerenes was performed with phenylpropyl and three different methoxyphenylpropyl bonded phases in microcolumn liquid chromatography. The results indicate that the 3,4‐dimethoxyphenylpropyl phase possesses the best resolving power among the evaluated phases, producing a separation factor of 1.87 for C 70 and C 60 using n ‐hexane as the mobile phase. This observation could be explained by examining the energy minimized conformations of the bonded phases and their associative interactions with the fullerene molecules.
