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.
