“…In the detection process of the residue of pesticide and veterinary drugs in food, MMOFs are characterized by easy preparation, simple operation and high adsorption efficiency, which can effectively reduce matrix interference and improve the detection sensitivity of the target [133][134][135][136]. Figure 8a has shown the synthesis of a MMOF (Fe 3 O 4 @ thioglycolic acid (TGA) @TMU-6) and the use for MSPE of some organophosphorus pesticides (OPPs) in rice and environmental water samples [137].…”

A variety of contaminants in food is an important aspect affecting food safety. Due to the presence of its trace amounts and the complexity of food matrix, it is very difficult to effectively separate and accurately detect them. The magnetic metal-organic framework (MMOF) composites with different structures and functions provide a new choice for the purification of food matrix and enrichment of trace targets, thus providing a new direction for the development of new technologies in food safety detection with high sensitivity and efficiency. The MOF materials composed of inorganic subunits and organic ligands have the advantages of regular pore structure, large specific surface area and good stability, which have been thoroughly studied in the pretreatment of complex food samples. MMOF materials combined different MOF materials with various magnetic nanoparticles, adding magnetic characteristics to the advantages of MOF materials, which are in terms of material selectivity, biocompatibility, easy operation and repeatability. Combined with solid phase extraction (SPE) technique, MMOF materials have been widely used in the food pretreatment. This article introduced the new preparation strategies of different MMOF materials, systematically summarizes their applications as SPE adsorbents in the pretreatment of food contaminants and analyzes and prospects their future application prospects and development directions.

“…Coordination polymers (CPs), composed of metallic nodes linked by organic ligands, are a class of organic-inorganic hybrid materials and have attracted more and more attention in recent years. [1][2][3][4][5][6][7][8][9][10] The physical and chemical properties of CPs can be rationally tuned due to the virtually limitless combination of highly tailorable metal ions and organic ligands. There are two branches of CPs which are porous coordination polymers (PCPs) or metal-organic frameworks (MOFs) and infinite coordination polymers (ICPs).…”

Coordination polymers (CPs) with aggregation-induced emission (AIE) have been widely applied to fluorescent sensing based on the strategy of electron or energy transfer. Novel strategies still need to be explored to promote the application of AIE CPs in fluorescent sensing. Herein, an infinite coordination polymer (ICP), synthesized from Zn 2 + , adenine and AIE ligand 4,4'-diphenic acid (DPA), was used to detect phosphate ion (Pi) via aggregation state modulation. The ICP was decomposed in the presence of Pi due to the coordination of Pi with Zn 2 + , which disaggregated AIE ligand DPA along with fluorescence quenching. The ICP quantified Pi in the concentration range from 30 to 600 μM with a detection limit of 5 μM, which was much lower than the physiological level, and was applied to detecting Pi in urine with spiked recoveries in the range of 82.0-115.5 %. This work provides a novel strategy to design fluorescent probes with AIE CPs for the analytes exhibiting the decomposing ability, promoting the application of AIE CPs in fluorescent sensing.

owing to its large molar absorption coefficients, high emission quantum yields, satisfactory chemical stability, and high tunability of photophysical properties. [10,11] The conventional BODIPY core has good structural stability, in which BF 2 -chelated inhibits the rotation around the CN pyrrole bridging bonds, which enhances the structural rigidity and endows the system with fluorescence emission properties. [12] The BODIPY core has 8 covalently modified positions, which can be divided into pyrrole ring carbons, the meso-carbon, and the boron atom. [11,13,14] These abundant active sites provide lots of possibilities to expand the structure of BODIPY derivatives through functionalization and to tune their photophysical properties. [15] In the past few decades, the structural modification strategies of BODIPY units and the resulting effects have been systematically explored, [4,16] providing a solid research foundation for the current-stage design and construction of various functional BODIPY derivatives for different occasions. After decades of development, by virtue of the high molar extinction coefficient, longer wavelength absorbing, outstanding photosensitivity, satisfactory internal stability, better biocompatibility relative to inorganic dyes, high light-dark toxicity ratios, and preferable photothermal conversion efficiency (PCE), [4,[17][18][19] there has been considerable interest in exploring the application of BODIPY as photosensitizers (PSs) in the area of phototherapy, which involves the production of reactive The use of boron dipyrromethene (BODIPY) in biomedicine is reviewed. To open, its synthesis and regulatory strategies are summarized, and inspiring cutting-edge work in post-functionalization strategies is highlighted. A brief overview of assembly model of BODIPY is then provided: BODIPY is introduced as a promising building block for the formation of single-and multicomponent self-assembled systems, including nanostructures suitable for aqueous environments, thereby showing the great development potential of supramolecular assembly in biomedicine applications. The frontier progress of BODIPY in biomedical application is thereafter described, supported by examples of the frontiers of biomedical applications of BODIPY-containing smart materials: it mainly involves the application of materials based on BODIPY building blocks and their assemblies in fluorescence bioimaging, photoacoustic imaging, disease treatment including photodynamic therapy, photothermal therapy, and immunotherapy. Lastly, not only the current status of the BODIPY family in the biomedical field but also the challenges worth considering are summarized. At the same time, insights into the future development prospects of biomedically applicable BODIPY are provided.
