Preparation and Characterization of 4,4-Dihydroxydiphenyl-Joined β-Cyclodextrin Bonded Silica Stationary Phase for High Performance Liquid Chromatography

A 4,4-dihydroxydiphenyl-bridged β-cyclodextrin bonded stationary phase(β-CD-D2-CSP) was prepared. The resulting bonded silica has been characterized by various methods. The chromatographic performances of β-CD-D2-CSP used for isomers' separation were investigated, and their mechanism of retention was discussed.
