Recently, food quality and safety have emerged as significant global issues. The rapid detection of contaminants spoilage markers has attracted increasing concerns. grouping illuminants based on the principle aggregation-induced emission (AIE) mechanism for designing monitoring analysis sensing platforms can address shortcomings conventional fluorophore aggregation-caused quenching (ACQ), offering benefits superb photoluminescence properties trace-level accuracy. With demand real-time in industry, such a robust platform is becoming progressively important. In current review, luminescence mechanisms structure design AIE are first introduced. elucidated, including noncovalent interaction, solubility viscosity change, specific recognition, photophysical quenching/dequenching processes. Moreover, this review comprehensively summarizes latest representative applications foodborne pathogens, environmental pollutants, biotoxins, agrochemicals, illegal additives, markers. Lastly, outlook challenges discussed. emerging exhibits outstanding advantages rapidity, high sensitivity, good accuracy analytes detection, well predestined capabilities constructing portable solid-state sensors. combination with other technologies, immunosensing techniques, freshness labels, smartphone platforms, further facilitate development commercialized especially portable, real-time, on-site applications. From typical organic molecules to nature-derived nanomaterials, discovery, synthesis different types substances under active exploration provide better solutions inspection.

Abstract To take advantage of the respective strengths aggregation‐induced emission (AIE) and aggregation‐caused quenching (ACQ) materials, in this paper a unique approach is taken which that tetraphenylethene triphenylamine (classical AIEs), borondipyrromethene benzothiadiazole ACQs) are selected to construct AIE@ACQ bimolecular systems by simple compounding method, focusing on effects optical properties such as fluorescence, photothermal therapy, phosphorescence, photodynamic therapy. Above all, mechanisms laws system preliminarily found. First, AIEs ACQs must, respectively, have electron‐acceptor electron‐donors form an intermolecular push–pull structure ensure two molecules close each other, π – stacking interaction separates highest occupied molecular orbitals lowest unoccupied reduce Δ E st , causing intriguing properties. Second, matching degree conjugate between also important factor. Utilizing these systems, it found different structural compositions possess synergy properties, so can be constructed according actual needs, advantages efficiency convenience, providing new idea for united application ACQs.

Abstract This study presents a novel boron‐difluoride complex‐based fluorescent nanofilm sensor capable of detecting sarin vapors in the environment by reporting an output fluorescence signal. The sensor's evaluation demonstrated exceptionally low detection limit for vapor, even presence various interfering gases, with theoretical and practical limits 0.7 1 ppb, respectively. featured rapid response time (less than 2 s), broad linear range (1 ppb–1000 ppm), superior selectivity vapor over group analytes, outperforming existing sensors. Mechanistic indicates that heightened sensitivity to is due robust affinity nitrogen atoms within core BODIQ unit sarin. Additionally, tetraphenylethylene structure steric hindrance effectively inhibits tight packing derivatives, forms numerous microporous structures self‐assembled nanofilm, which are beneficial mass transfer, enhancing efficiency vapors. Furthermore, we have achieved differentiation sarin, diethyl chlorophosphate, HCl through analysis sensing kinetic. opens new avenues sustainable, low‐cost, environment‐friendly portable devices, as well environmental monitoring tracking applications.
