[Preparation and evaluation of C60 bonded silica phase for high performance liquid chromatography]

C60 was chemically attached to gamma-(ethylenediamino) propylsilyl-bonded silica as a stationary phase for liquid chromatography. The new stationary phase was used to investigate the separations of polycyclic aromatic hydrocarbons (PAHs) and tert-butylcalix[n]arenes. The elution order of PAHs was found to be similar to that on octadecylsilica (ODS); the elution order of tert-butylcalix[n]arenes was found to be tert-butylcalix[8]arene, tert-butylcalix[4]arene and tert-butylcalix[6]arene with 1%(V/V) isopropanol/cyclohexane as a mobile phase.
