AB  - A novel chiral covalent organic framework (CCOF) was synthesized with an imine 
      covalent organic framework TpBD (synthesized via Schiff-base reaction between 
      phloroglucinol (Tp) and benzidine (BD)) modified using 
      (1S)-(+)-10-camphorsulfonyl chloride as chiral ligand by chemical bonding method 
      for the first time, and was characterized by X-ray diffraction, Fourier-transform 
      infrared spectra, X-ray photoelectron spectroscopy, nitrogen 
      adsorption/desorption, thermogravimetry analysis, and zeta-potential. The results 
      revealed that the CCOF had good crystallinity, high specific surface area and 
      good thermal stability. Then, the CCOF was employed as stationary phase in 
      open-tubular capillary electrochromatography (OT-CEC) column (the CCOF-bonded 
      OT-CEC column) for enantioseparation of 21 single chiral compounds (12 natural 
      amino acids including acidic, neutral and basic, 9 pesticides including 
      herbicides, insecticides and fungicides) and simultaneous enantioseparation of 
      mixture amino acids and pesticides with similar structures or properties. Under 
      the optimized CEC conditions, all the analytes reached the baseline separation 
      with high resolutions of 1.67-25.93 and selectivity factors of 1.06-3.49 in 
      8 min. Finally, the reproducibility and stability of the CCOF-bonded OT-CEC 
      column were measured. Relative standard deviations (RSDs) of retention time and 
      separation efficiency were 0.58-4.57% and 1.85-4.98%, and not obviously changed 
      after 150 runs. These results demonstrate that COFs-modified OT-CEC explore a 
      promising method to separate chiral compounds.
