“…Chen et al prepared a novel CD-fluorinated covalent organic framework (CD-F-COF) resin to enrich seven benzene series and three perfluorooctane sulfonic acids in food samples ( Figure 5 ). This method can enrich the traces of multiple targets in a rapid and high-throughput manner [ 114 ]. Belenguer-Sapina et al prepared an innovative material based on mesoporous silica modified with CDs to extract and detect endocrine-disrupting chemicals from bottled apple juice [ 115 ].…”

Food safety issues are a major threat to public health and have attracted much attention. Therefore, exploring accurate, efficient, sensitive, and economical detection methods is necessary to ensure consumers’ health. In this regard, cyclodextrins (CDs) are promising candidates because they are nontoxic and noncaloric. The main body of CDs is a ring structure with hydrophobic cavity and hydrophilic exterior wall. Due to the above characteristics, CDs can encapsulate small guest molecules into their cavities, enhance their stability, avoid agglomeration and oxidation, and, at the same time, interact through hydrogen bonding and electrostatic interactions. Additionally, they can selectively capture the target molecules to be detected and improve the sensitivity of food detection. This review highlights recent advances in CD inclusion technology in food safety analysis, covering various applications from small molecule and heavy metal sensing to amino acid and microbial sensing. Finally, challenges and prospects for CDs and their derivatives are presented. The current review can provide a reference and guidance for current research on CDs in the food industry and may inspire breakthroughs in this field.

“…[ 66 ] For instance, a fCOF constructed from 2,3,5,6‐tetrafluoroterephthalaldehyde and 1,3,5‐tris(4‐aminophenyl)triazine building blocks were functionalized by cyclodextrin (CD) functional groups to synthesize the β ‐CD modified COF (CD‐F‐COF), which was further incorporated with the polymer binder polydimethylsiloxane and nylon‐66 substrate (Figure 7B). [ 67 ] Taking the advantages of fluorophilic effect and host–guest interaction, the as‐prepared CD‐F‐COF coated membrane shows simultaneous enrichment for seven bisphenols and three PFASs from the food packaging and samples, displaying the limits of the detection range of 0.006–0.050 ng g −1 for bisphenols and 0.001–0.008 ng g −1 for PFASs.…”

Covalent organic frameworks (COFs) are a type of crystalline porous polymers that possess ordered structures and eternal pores. Because of their unique structural characteristics and diverse functional groups, COFs have been used in various application fields, such as adsorption, catalysis, separation, ion conduction, and energy storage. Among COFs, the fluorine‐containing COFs (fCOFs) have been developed for special applications by virtue of special physical and chemical properties resulting from fluorine element, which is a nonmetallic halogen element and possesses strong electronegativity. In the organic chemistry field, introducing fluorine into chemicals enables those chemicals to exhibit many interesting properties, and fluorine chemistry increasingly plays an important role in the history of chemical development. The introduction of fluorine in COFs can enhance the crystallinity, porosity, and stability of COFs, making COFs having superior performances and some new applications. In this review, the synthesis and application of fCOFs are systematically summarized. The application involves photocatalytic production of hydrogen peroxide, photocatalytic water splitting, electrocatalytic CO2 reduction, adsorption for different substances (H2, pesticides, per‐/polyfluoroalkyl substances, polybrominated diphenyl ethers, bisphenols, and positively charged organic dye molecules), oil−water separation, energy storage (e.g., zinc‐ion batteries, lithium−sulfur batteries), and proton conduction. Perspectives of remaining challenges and possible directions for fCOFs are also discussed.

“…The techniques above are time-consuming and energy-intensive for the separation and enrichment of large volumes of liquid samples. Membrane-based SPE allows for rapid enrichment of large volumes at low pressures, thus reducing the sample preparation time [14][15][16]. An in-syringe membrane-based extraction is a typical form of SPE, providing an effective method for rapid and convenient extraction of the analytes.…”

A highly chemically stable primary amide-functionalized cyclotricatechylene covalent organic framework was synthesized by an irreversible reaction and a post-synthetic modification. It possessed a rod-like morphology and exhibited strong solvent stability owing to the polyether bonds. The material showed good adsorption performance for melamine and its derivatives and adsorption mechanism was investigated by molecular simulations. The adsorbent was coated on the nylon-66 membrane to prepare the enrichment membrane. Under optimized conditions, an in-syringe membrane-based extraction method, combined with ultra-high performance liquid chromatography-tandem mass spectrometry was developed for the analysis of melamine and six melamine derivatives in the migration solution. A good linearity was obtained with correlation coefficients ranging from 0.9924 to 0.9995. The limits of detection were 1-200 ng/L and the limits of quantification were 3-500 ng/L. This method was successfully applied to the migration solution of sushi bamboo rolling mats with spiked recoveries of 73.2%-115% and relative standard deviations of 0.9%-9.9%. This work shows a practical and perspective approach for the efficient enrichment of food contact material hazards.
