英文摘要A hybrid monolithic capillary column synthesized with (3-chloropropyl)-trimethoxysilane (CPTMS) and tetramethoxysilane (TMOS) via sol-gel chemistry was in situ coated with cellulose tris(3,5-dimethylphenyl-carbamate) (CDMPC) for enantioseparations in capillary electrochromatography (CEC) and capillary liquid chromatography (CLC). Prior to coating, the prepared CP-silica hybrid monolith was straightforwardly modified with diethylenetriamine (DETA) to introduce -NH2 functionalities via the nucleophilic substitution reaction, which generate the stronger EOF for CEC. The coating condition was optimized to obtain a stable and reproducible chiral stationary phase for enantioseparation. The results indicated that racemic benzoin was baseline separated on the resulting hybrid monolith coated with 30 mg/mL CDMPC in CEC, while several racemates were successfully enantioseparated on the resulting CP-silica hybrid monolithic column coated with 60 mg/mL CDMPC in CLC with RP and NP modes.
