    Abstract:
    This work describes the investigation of separation performance of the p-tert-butyl(tetradecyloxy)calix[6]arene (C6A-C10-OH) as stationary phase for gas chromatography (GC) separations. Its structure was characterized by IR, 1H NMR, 13C NMR, MS and single-crystal X-ray diffraction analysis. The C6A-C10-OH column shows good separation capacity for aliphatic, aromatic and cis-/trans- isomers. Especially, it exhibits multiple molecular recognition interactions for the analytes with a wide range of polarity, including dispersion, π-π, H-bonding and dipole-dipole interactions. The present work provides experimental and theoretical basis for the designing of the new calixarene stationary phases in GC analyses.
