Article Abstract
In this work, a novel fluorinated magnetic microporous organic network (FeO@FMON) was exquisitely designed and synthesized for highly efficient and selective magnetic solid phase extraction (MSPE) of fluorinated benzoylurea insecticides (BUs) from complex tea beverage samples. The FeO@FMON exhibited good extraction for BUs via the pre-designed hydrophobic, π-π stacking, hydrogen bonding and specific FF interactions. A sensitive FeO@FMON-based MSPE-HPLC-UV method with wide linear range (0.10-1000 μg L, R ≥ 0.996), low limits of detection (0.01-0.02 μg L), and large enrichment factors (85.6-98.0) for BUs from tea beverage samples was developed. By decorating F elements within MON's networks, the FeO@FMON characterized good hydrophobicity and chemical stability, which could be reused at least 8 times without decrease of recoveries. This work demonstrated the great prospects of FeO@FMON for enriching trace BUs from complex substrates and triggered the potential of FMON for sample pretreatment of fluorinated analytes.

Five alkali metal manganese(III) fluorophosphates, KMn(POF)F (I), RbMn(POF)F (II), RbMn(POF)(PO)F (III), RbMn(POF)(PO)F (IV), and CsMn(POF)F (V), were successfully synthesized using a hydrothermal method. The monofluorophosphate anion (POF) groups work as "chemical scissors" to promote low-dimensional spin structures with the aid of alkali metal cations. I and II had an = 2 uniform chain structure formed by corner-sharing -MnOF octahedra.

Considering the widespreadly use, large consumption, and serious environmental and health threats of phenylpyrazole insecticides (PPIs), development of a selective and sensitive method for accurate detection of their residuals in food samples is of great significance and challenging. Herein, depending on the hydrophobic and F-containing characteristics of PPIs, a novel fluorinated magnetic microporous organic network (FMMON) was designed and prepared for efficient and selective magnetic solid-phase extraction (MSPE) of two typical PPIs (fipronil and ethiprole) from milk and egg samples before the HPLC-UV determination. FMMON owned large specific surface area, multiple interaction sites, excellent magnetic separation performance and stability and exhibited good extraction and selectivity for fipronil and ethiprole through the specific F-F, hydrogen bonding, hydrophobic, and π-π interactions.

Enterohepatic circulation (EHC) is a critical biological process for the normal regulation of many endogenous biomolecules and the increased retention of various exogenous substances. The status of EHC is closely related to the ordinary functioning of several digestive organs. However, it remains a challenge to achieve in vivo real-time visualization of this process.

Perfluorooctane sulfonate (PFOS), a widely distributed and persistent organic pollutant, is known to cause immune dysfunction. In a previous study, we reported that PFOS modestly increases mast cell activation. However, its effects on FcεRI (a high-affinity IgE receptor)-mediated mast cell activation, a pivotal process in inflammatory allergic reactions and innate immunity, have not been clearly demonstrated.

Urinalysis, as a non-invasive and efficient diagnostic method, is very important but faces great challenges due to the complex compositions of urine and limited naturally occurring biomarkers for diseases. Herein, by leveraging the intrinsic absence of endogenous fluorinated interference, a strategy with the enzymatically activated assembly of synthetic fluorinated peptide for cholestatic liver injury (CLI) diagnosis and treatment through F nuclear magnetic resonance (NMR) urinalysis and efficient drug retention is developed. Specifically, alkaline phosphatase (ALP), overexpressed in the liver of CLI mice, triggers the assembly of fluorinated peptide, thus, directing the traffic and dynamic distribution of the synthetic biomarkers after administration, whereas CLI mice display much slower clearance of peptides through urine as compared with healthy counterparts.
