Synthesis and characterization of phosphodiester stationary bonded phases for liquid chromatography.

The new type of stationary bonded phases for liquid chromatography with immobilized artificial membrane properties was synthesized. Based on the modification of diol-bonded silica gel the phosphodiester stationary phases were obtained. The structures of synthesized material were confirmed by different physico-chemical techniques such as elemental analysis, infrared spectroscopy (FTIR), (13)C CP/MAS NMR and in reversed phase and hydrophilic interaction liquid chromatography, where hydrophobic and polar compounds were sufficiently separated. To present the influence of phosphate group on the retention properties, obtained material were compared with Diol-Ester C12 stationary phase.
