AB  - Controllable synthesis of micro-flower covalent organic frameworks (MFCOFs) with 
      controllable size, monodisperse, spherical, and beautiful flower shape was 
      realized by using 2,5-diformylfuran (DFF) and p-phenylenediamine (p-PDA) as 
      building blocks at room temperature. High-quality MFCOFs (5 - 7 mum) were 
      synthesized by controlling the kind of solvent, amounts of monomers, catalyst 
      content, and reaction time. The synthesized MFCOFs possessed uniform mesopores 
      deriving from the intrinsic pores of frameworks and wide-distributed pores 
      belonging to the gap between the petals. The MFCOFs-packed solid-phase extraction 
      (SPE) column shows adsorption capacity of about 8.85 mg g(-1) for 
      2,4-dichlorophenol (2,4-DCP). The MFCOF-based SPE combined with the HPLC method 
      was established for the determination of 2,4-DCP in environmental water. The 
      linear range of this method is 20-1000 ng mL(-1) (R(2) > 0.9994), and limit of 
      detection (S/N = 3) is 10.9 ng mL(-1). Spiked recoveries were 94.3-98.5% with 
      relative standard deviations lower than 2.3%.
