Covalent organic frameworks (COFs) are attractive materials receiving increasing interest in the literature due to their crystallinity, large surface area, and pore uniformity. Their properties can be tailored towards specific applications by judicious design of COF building blocks, giving access to tailor‐made pore sizes and surfaces. In this Concept article, developments in the field of COFs that have allowed these materials to be explored for contaminant adsorption are discussed. Strategies to obtain water‐stable materials with highly ordered structures and large surface areas are reviewed. Post‐synthetic modification approaches, by which pore surfaces can be tuned to target specific contaminants, are described. Recent advances in COF formulations, crucial for future implementation in adsorption devices, are highlighted. At the end, future challenges which need to be addressed to allow for the deployment of COFs for the capture of water contaminants will be discussed.

“…The unique properties of COFs also make them promising in the field of separation science including solid-phase extraction (SPE) [19,20], solid phase microextraction (SPME) [21][22][23], capillary electrochromatography (CEC) [24][25][26], high performance liquid chromatography (HPLC) [27][28][29][30][31] and gas chromatography (GC) [32,33]. In case of the studies of COFs as novel stationary phases for GC separation, to the best of our knowledge, only two examples can be found in the relevant literature.…”

Covalent organic frameworks are a new class of crystalline porous materials that have various potential applications. However, utilization of covalent organic frameworks as new stationary phases for gas chromatography separation has been less explored. In this work, a hydrazone‐linked chiral covalent organic framework has been covalently bonded onto the inner surface of fused silica capillary. The fabricated hydrazone‐linked covalent organic framework‐bound capillary column displays a moderate polarity nature and exhibits relatively high resolution performances for separation of linear alkanes and alcohols, as well as aromatic positional isomers including xylene, nitrotoluene, chloronitrobenzene, benzenediol, and naphthol isomers. The present study reveals that the hydrazone‐linked covalent organic framework‐bound capillary column is quite promising for the gas chromatography separation of aromatic positional isomers.

Porous Organic Frameworks: Advanced Materials in Analytical Chemistry

Porous organic frameworks (POFs), a general term for covalent‐organic frameworks (COFs), covalent triazine frameworks (CTFs), porous aromatic frameworks (PAFs), etc., are constructed from organic building monomers with strong covalent bonds and have generated great interest among researchers. The remarkable features, such as large surface areas, permanent porosity, high thermal and chemical stability, and convenient functionalization, promote the great potential of POFs in diverse applications. A critical overview of the important development in the design and synthesis of COFs, CTFs, and PAFs is provided and their state‐of‐the‐art applications in analytical chemistry are discussed. POFs and their functional composites have been explored as advanced materials in “turn‐off” or “turn‐on” fluorescence detection and novel stationary phases for chromatographic separation, as well as a promising adsorbent for sample preparation methods. In addition, the prospects for the synthesis and utilization of POFs in analytical chemistry are also presented. These prospects can offer an outlook and reference for further study of the applications of POFs.
