“…26 Tang et al combined triazinebased POP with bacterial cellulose nanofiber aerogels to adsorb organophosphorus pesticide. 27 However, using triazine-based POPs for the adsorption of aflatoxins has not yet been reported. In addition, recent studies have confirmed that attaching functional groups to the POP can provide highly active sites for the analyte adsorption, thereby enhancing the adsorption efficiency.…”

Food safety issue caused by aflatoxins has aroused widespread concern in society. Herein, a novel fluorine-functionalized triazine-based porous organic polymer (F-POP) was developed for the first time by the simple condensation polymerization of 2,2′-bis(trifluoromethyl)benzidine and cyanuric chloride. With in-built fluorine functional group (F) and imine group (−NH−), F-POP displayed significantly superior adsorption ability for aflatoxins, outperforming fluorine-free POP due to the multiple interaction mechanisms of hydrogen bond, F–O interaction, π–π interaction, F−π interaction, and hydrophobic interaction. Thus, magnetic F-POP was prepared by introducing Fe3O4 into F-POP and then utilized as a magnetic sorbent for the extraction of trace aflatoxins in peanut and rice samples prior to high-performance liquid chromatography-fluorescence detection. Under the optimal conditions, the proposed method presented high sensitivity with the limit of detections at 0.005–0.15 ng g–1. F-POP also exhibited outstanding adsorption capability for many other organic pollutants, revealing its great potential for analysis or adsorption applications.
