Recognition and detection of Fe3+ Al3+ ions in water are important for human health life. Herein, a novel multifunctional fluorescence sensor based on zinc-based metal-organic frameworks (Zn-MOF) was developed using zinc nitrate hexahydrate pyridine-2,5-dicarboxylic acid by solvothermal condition, characterized X-ray single crystal diffraction, elemental analysis, powder diffraction (PXRD), etc. The PXRD experiment results observed that the structure Zn-MOF is rearranged after molecules exchanged all 3 DMF solvates pores. Fluorescent sensing experiments revealed exhibits high sensitivity detecting significant quenching.The limit (LOD) were 0.18 μM 0.064 μM, respectively. anti-interference revealing has selectivity to detect Al3+. In addition, quenching mechanism demonstrated be attributed inner filter effect (IFE). Furthermore, real sample tap water, recoveries 103.0% - 107.9% 106.1% 110.5%, respectively, relative standard deviations (RSD) less than 7.42% 6.20%, This work provided an reliable method quantitative successfully applied with satisfactory recovery precision.

ABSTRACT The bowl‐shaped flexible carboxylic acid zwitterion 1,1′,1″‐(2,4,6‐trimethylbenzene‐1,3,5‐triyl)tris (methylene)‐tris(4‐carboxy‐pyridinium)tribromide (H 3 L Br ) ligand‐based lanthanide metal–organic framework (Ln‐MOF) was synthesized for the first time under solvothermal conditions. Single crystal X‐ray diffraction analysis indicates that molecular formula of Ln‐MOF is [Eu 2 O) 4 ]·2H O ( 1 ). Luminescence sensing experiments demonstrate shows obvious fluorescence quenching nitrobenzene (NB), Fe 3+ , and Cr 7 2− with low detection limits 0.118 μM, 9.098 nM, 17.409 respectively. can be regarded as a luminescence sensor multiple functions, displaying high selectivity, wonderful antiinterference ability, outstanding sensitivity, recyclability to detect NB, .
