3-(Aza-18-crown-6) propylsilyl-bonded silica, a new stationary phase for high-performance liquid chromatography, is synthesized for the first time using two different reaction routes. The stationary phase is characterized by means of elemental analysis, infrared spectra, and the measurement of complexing capacity with some metal ions. The chromatographic behavior of the stationary phase is also studied with disubstituted benzenes, amino acids, nucleosides, and nucleobases as solutes. The retention and selectivity of different compounds on the bonded phase depend on the hydrophobicity, dipolarity, hydrogen bonding, and host–guest complexation interaction according to the property and composition of the mobile phases used.
