AB  - A fluorinated covalent organic framework composed of 
      2,3,5,6-tetrafluoroterephthaldehyde (TFA) and 1,3,5-tri(4-aminophenyl)benzene 
      (TAPB) is proposed for electrochromatographic separation. TFA-TAPB is for the 
      first time regarded as the stationary phase of capillary electrochromatography. 
      The TFA-TAPB-coated capillary columns exhibited satisfactory separation 
      (resolution values > 1.5) and good reproducibility towards fluoroquinolones. The 
      intraday relative standard deviations (RSDs) of retention time and peak areas 
      were 0.54-0.68% and 1.69-2.82%, respectively. The interday RSDs of retention time 
      and peak areas were less than 1.79% and 2.30%, respectively. The column-to-column 
      RSDs of retention time and peak areas were 0.22-0.73% and 0.74-1.86%, 
      respectively. And, the inter-batch RSDs of retention time and peak areas were 
      less than 0.39% and 1.67%, respectively. Moreover, the possible separation 
      mechanism was discussed, and it was found that the pi-pi stacking effect, 
      hydrophobic interaction, hydrogen bonding, and fluorous interactions were the 
      main factors. Overall, these results demonstrated that TFA-TAPB has high prospect 
      for CEC separation.
