| Abstract: | A terminal-vinyl liquid crystal 4’-(ω- undecenyloxyl)-4-xenol was synthesized and used to modify terminal-vinyl organic-inorganic hybrid silica monolithic column by free radical polymerization procedure using AIBN as an initiator. Naphthol, PAHs, phthalate ester and steroids were successfully separated on the column and the separation effects were compared with unmodified column. Mechanism was inferred to hydrophobic interaction, π-π interaction and hydrogen bonding. Reproducibilities of migration times for steroids were reasonable with RSD less than 3.27% for five consecutive within-column runs and were 7.39-9.05% for column-to-column measurements of three columns, respectively. |
