Advanced techniques for both environmental and biological prescription drug monitoring are of ongoing interest. In this work, a fluorescent sensor based on an Eu3+-doped anionic zinc-based metal–organic framework (Eu3+@Zn-MOF) was constructed rapid visual analysis the molecule demecycline (DEM), achieving high sensitivity selectivity. The ligand 2-amino-[1,1′-biphenyl]-4,4′-dicarboxylic acid (bpdc-NH2) not only provides stable cyan fluorescence (467 nm) through intramolecular charge transfer bpdc-NH2 infinitesimal disturbanced by Zn2+ but also chelates Eu3+, resulting in red (617 fluorescence. Through synergy photoinduced electron antenna effect, bidirectional response to DEM is achieved, enabling concentration quantification. Eu3+@Zn-MOF platform exhibits wide linear range (0.25–2.5 μM) detection limit (LOD) 10.9 nM. Further, we integrated sensing into paper-based system utilized smartphone water samples milk products, demonstrating potential large-scale, low-cost utilization technology.

In this paper, carbon dot (CD)-encapsulated 1,3,5-tris(4-formylphenyl)benzene (TFB)/2,5-dihydroxyterephthalohydrazide (DHTH) covalent organic frameworks (TDCOFs) grafted with thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) (CDs@TDCOFs@PNIPAM) were fabricated for the detection of pyrethroids. CDs@TDCOFs@PNIPAM achieved a temperature-responsive "on/off" pyrethroids based on target-triggered electron-transfer mechanism. The limit was as low 0.69 μg/L in wide linear range 5-400 (R2 > 0.9523). Simultaneously, red, green, and blue (RGB) fluorescence emissions integrated smartphone-assisted device, enabling visual smart quantitative 4.875 μg/L. Ultimately, agricultural products chosen actual samples to verify applicability both recognition modes, calculated recovery rate 105.48-113.40%. Accordingly, featuring switching behavior RGB emission provided promising analytical strategy ensuring food safety.
