Zinc-based MOFs exhibit significant advantages in ion detection due to their unique structure and chemical properties. They can efficiently selectively recognize detect specific ions, making them powerful analytical tools for applications environmental monitoring, biomedical fields, more. In this work, we used a simple ligand improve the coordination environment of Zn2+ ions successfully synthesized 3D compound Zn(all-bdc)(Py) MOF through straightforward hydrothermal method at low temperature. Additionally, explored potential as bifunctional fluorescence probe both cationic anionic recognition. The results showed that porous exhibited excellent recognition ability trivalent iron (Fe3+) potassium permanganate (KMnO4−) its highly structures efficient When were added 500 μL 100 μL, was effectively quenched, limits these two 0.95 μM 0.13 μM, respectively. mixed-ion experiments also demonstrated even presence similar still maintained good selective ability, specifically identifying Fe3+ KMnO4− ions. This work provides novel synthetic strategy design capable detection, expanding application sensing analysis.
