Four chiral organosilanes based on O,O’-dibenzoyl tartardiamide, O,O’-bis-(3,5-dimethylbenzoyl) tartardiamide, O,O’-bis-(phenylcarbamoyl) tartardiamide and O,O’-bis-[(3,5-dimethylphenyl)carbamoyl] tartardiamide were synthesized and immobilized on silica to afford corresponding brush-type chiral stationary phases (CSPs) with well-defined structures. Using 54 compounds containing a wide variety of structures as analytes, the enantioselectivities of the four CSPs were evaluated under normal-phase modes. 3,5-Di-Me substituent in the aryl group was found to significantly affect the enantioselectivity of CSPs containing aryl ester moieties. Aryl carbamate moieties in CSPs were observed more beneficial for enantioseparation than aryl ester moieties. The addnl. hydrogen-bond donors (NH) present in the carbamate groups contributed greatly to the enantioselectivity of CSPs, which is contrary to the results that were found in network-polymeric CSPs.
