AB  - The high stability and other properties of Zr(IV)-based metal organic 
      frameworks(MOFs) make it a promising choice for chromatographic separation, while 
      the application in open-tubular capillary electrochromatography (OT-CEC) 
      separation has not been explored yet. Herein, we report the first example of the 
      in-situ growth of UiO-66-NH(2) onto the capillary for open-tubular capillary 
      electrochromatography. UiO-66-NH(2) consists of ZrCl(4) and 
      2-amino-1,4-benzenedicarboxylic acid, which is highly porous and stable in a 
      variety of solvents. The prepared UiO-66-NH(2) modified capillary was 
      characterized by scanning electron microscopy (SEM) and Fourier transform 
      infrared spectra (FT-IR), and the results confirmed the successful growth of the 
      UiO-66-NH(2) . The baseline separation of chlorobenzenes, phenoxyacids and two 
      groups of phenols was achieved owing to the combined interaction of pi-pi 
      interaction, hydrophobic interaction, molecular sieve effect, electrophoretic 
      migration and hydrogen-bonding interaction etc. Besides, the prepared capillaries 
      showed good reproducibility, with relative standard deviations (RSDs) for 
      intra-day, inter-day and column-to-column runs in the range of 1.38-2.60%, 
      3.39-4.05%, and 3.47-5.03%, respectively. Our work indicates Zr(IV)-based MOFs 
      are promising materials as stationary phase in CEC separation.
