Applied Organometallic Chemistry, Год журнала: 2025, Номер 39(3)

Опубликована: Фев. 24, 2025

ABSTRACT One 3D Zn‐MOF , namely, {[Zn 2 (L)(OH)(DMF)]} n was selected based on the flexible ether oxygen carboxylic acid 3‐(3,5‐dicarboxylatobenzyloxy)benzoic (H 3 L). able to specifically recognize biomarker methylmalonic (MMA) and antibiotic tetracycline (TC) through fluorescence enhancement ratio mechanism, with detection limits (LOD) as low 1.29 0.26 μM, respectively. It also has high selectivity rapid response characteristics. In particular, visual significantly enhanced in presence of Tb 3+ antenna effect. To explore potential application, fluorescent test strips mixed matrix membrane (MMM) were successfully prepared realize detection. The recovery rates MMA TC simulated urine actual water systems 95.3%–100.5% 93.5%–94.7%, respectively, indicating that provided possibility for detecting practical systems.

1-Hydroxypyrene (1-HP) is known as the end product of polycyclic aromatic hydrocarbons (PAHs). Monitoring content 1-hydroxypyrene in human urine or serum can help measure degree hydrocarbon poisoning body. Tryptophan (Trp), one eight essential amino acids, plays a vital role growth and development. Therefore, exploration promising sensor for instant accurate recognition 1-HP Trp has profound influence on health. Herein, three-dimensional (3D) europium-centered metal–organic framework ([Eu(H2O)5]0.33[Eu(obdb)]·2DMF, Eu-MOF) with amazing air stability, acid–base thermal stability was constructed through coordination interaction between Eu(III) ions V-typed semirigid ligand two isophthalate groups (H4obdb, 4′,4‴-oxybis([1,1′-biphenyl]-3,5-dicarboxylic acid)) under solvothermal condition. As expected, Eu-MOF recognize binary solutions DMF-H2O based significantly luminescent turn-off effect high quenching efficiencies (99.2% 93.8% Trp), charming constants (2.15 × 104 M–1 4.88 low limit detection (1.10 μM 0.73 satisfactory antijamming capability. In addition, Trp, color change from red to blue visible naked eye concentration increases 365 nm UV lamp. Moreover, except solutions, sensing capacities toward are proven be comparable HEPES buffer solution real samples.

Design and Construction of a Porphyrin-Based Samarium(III)-Metal–Organic Framework for Antibiotic Detection

Inorganic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Янв. 8, 2025

Porphyrins bearing the unique 18π electron tetrapyrrolic macrocycles exhibit interesting photophysical and photochemical properties have been considered as promising ligands for construction of functionalized metal–organic frameworks (MOFs). The combination porphyrin-type with lanthanide metals featured diverse coordination environments to realize novel functions well diversity MOF is thus attractive but challenging. Herein, an unprecedented porphyrin-based samarium (Sm-BCPP) composed a 5,10-bis(4-carboxyphenyl)-10,20-diphenyl porphyrin (H2BCPP) ligand samarium-formed one-dimensional clusters has constructed via solvothermal approach, synthesized Sm-BCPP excellent chemical stabilities, exhibiting red luminescence. Interestingly, demonstrated fluorescence quenching against commonly used antibiotics, showing ultrahigh constant (KSV) ultralow detection limit (LOD), among which rifampicin (LOD = 0.33 nM) nitrofurazone 0.24 was found be lower than most reported materials. Encouragingly, exhibited stability in aqueous solutions at different pH environments, capability natural water environment indicated its practical application potential. in-depth studies suggested that mechanism antibiotics involved internal filtration effect photoinduced transfer.
