AI Article Synopsis
- This study created a special way to find quinolones (QNs) in food using a new material made from NiFeO that can attract QNs.
- They used a fancy machine called UHPLC-Q-Orbitrap HRMS to check for 18 different types of QNs at super small amounts.
- The method worked really well, getting good results from tests on liver and kidney samples, showing that it’s a smart way to find bad stuff in food.
Article Abstract
This study aimed to present a selective and effective method for analyzing quinolones (QNs) in food matrix. Herein, a NiFeO-based magnetic sodium disulfonate covalent organic framework (NiFeO/COF) was prepared using a simple solvent-free grinding method, and was adopted as a selective adsorbent for magnetic solid phase extraction of QNs. Coupled with UHPLC-Q-Orbitrap HRMS, an efficient method for simultaneous detection of 18 kinds of QNs was established. The method exhibited good linearity (0.01-100 ng g), high sensitivity (LODs ranging from 0.0011 to 0.0652 ng g) and precision (RSDs below 9.5%). Successful extraction of QNs from liver and kidney samples was achieved with satisfactory recoveries ranging from 82.2% to 108.4%. The abundant sulfonate functional groups on NiFeO/COF facilitated strong affinity to QNs through electrostatic and hydrogen bonding interactions. The proposed method provides a new idea for the extraction of contaminants with target selectivity.

An innovative core-shell covalent organic framework (COF), FeO@COF (ETTBA-ND), was synthesized through a facile and energy-efficient method. This adsorbent facilitated magnetic solid phase extraction (MSPE) of six AFs prior to LC-MS/MS analysis, achieving one-step purification and enrichment in food matrices. The successful synthesis of the adsorbent was confirmed using various techniques, with adsorption capacities ranging from 46.

An in situ self-cleaning covalent organic framework featuring arylbiguanide arms (Aryl-BIG-COF) was first developed to remove emerging organic pollutants such as propranolol (PRO) from water. The main breakthroughs addressed the scarcity of functional active sites, the impracticality of ex situ regeneration, and the rapid recombination of electronhole pairs in the application of COFs. Owing to the directional capture ability and electronic structure regulation of the arylbiguanide arms, the adsorption capacity and photocatalytic degradation rate of the newly synthesized COF increased by nearly four and seven times, respectively.

Enzymatic proteolysis is the key process to produce bioavailable nitrogen in natural terrestrial and aquatic ecosystems for microorganisms and plants. However, little is known on how protein degradation is influenced by organic contaminants. As we known, the overuse of organophosphate esters (OPEs) has caused serious pollution in soil, water, and sediment.

The direct incorporation of borondipyrromethene (BODIPY) subunits into the structural backbone of covalent organic frameworks (COFs) gives facile access to porous photosensitizers but is still a challenging task. Here, we introduce β‑ketoenamine-linked BDP‑TFP‑COF, which crystallizes in AA‑stacking mode with hcb topology. A comprehensive characterization reveals high crystallinity and enhanced stability in a variety of solvents, excellent mesoporosity (SABET = 1042 m2 g-1), broad light absorption in the visible region, and red emission upon the exfoliation of few-layer COF nanosheets.

We report herein the synthesis of an unprecedented isomer of perylene, dicyclohepta[cd,fg]-as-indacene bearing two phenyl groups (1-Ph) by the nickel-mediated intramolecular homocoupling of a 4,4'-biazulene derivative (2). The X-ray crystallographic analysis and theoretical calculations revealed that 1-Ph adopts a unique helically twisted geometry although the local aromaticity of azulene moieties was preserved. The double covalent linkage of the two azulene skeletons imparts significant orbital interaction, which affords near-infrared (NIR) absorption (up to 1720 nm) and remarkable redox behaviors despite its closed-shell electronic structure.
