AB  - Microporous organic polymers (MOPs) are an emerging class of functional porous 
      materials for diverse potential applications. Typically, tailored microporous 
      structures of MOPs are generated by linkages of organic polymerizable monomer 
      building blocks, providing high permanent porosity and excellent stability. 
      Herein, we reported the first example of the application of organic building 
      block based MOPs (OBB-MOPs) as efficient enrichment media for sample preparation. 
      A novel multilayer interbridging strategy was proposed to fabricate OBB-MOP 
      coatings, and hereby SNW-1 (a kind of OBB-MOPs) was coated on silica substrate 
      with well-controlled thickness. Strong covalent bonds throughout the network and 
      interlayer bridging improved the durability of the coating significantly. 
      Outstanding chemical stability was observed in diverse solvents as well as 
      solutions with a wide range of pH or high ionic strength and even under extremely 
      harsh conditions like boiling water. The SNW-1 coating possessed a microporous 
      network structure constructed of conjugated and nitrogen-rich building blocks. 
      Thus, the coating exhibited a superior enrichment performance of polycyclic 
      aromatic hydrocarbons and volatile fatty acids (VFAs) over commercial coatings 
      based on interactions including pi-pi affinity and acid-base interaction. For 
      further application, this coating was combined with gas chromatography/mass 
      spectrometry for the noninvasive analysis of VFAs from tea leaf and tobacco shred 
      samples. The low detection limits of 0.014-0.026 mug/L were achieved with the 
      relative standard deviations (RSDs) between 4.3 and 9.0%. Consequently, trace 
      original VFAs from the samples were detected. Good recoveries were obtained in 
      the range of 90-129% and 77-118% with the corresponding RSDs (n = 3) of 2.6-9.3% 
      and 1.9-10%, respectively.
