An efficiently selective sensor for aquatic antibiotic detection based on a photoluminescent cadmium metal-organic framework (Cd-MOF) is researched in this work. The novel and simple luminescent MOF that composed from aπ-electron rich ligand bip (3,5-bis(1-imidazol) pyridine) and H3L (2-nitro-5-(4-carboxy-2-nitrophenoxy) isophthalic) was synthesized in hydrothermal condition and characterized. Single crystal X-ray diffraction anal. demonstrated that it had an uncommon 2-nodal (3,6)-connected 3D framework with a (32·4)(34·46·53·62) topol., which could be formulated as [{[Cd2(HL)2(bip)2]·H2O}n]. Benefiting from its unique framework, [{[Cd2(HL)2(bip)2]·H2O}n] can not only respond to the trace quantity of chloramphenicol (CHL) via fluorescence quenching but also show good adsorption capability toward CHL in aqueous solution The selective response to CHL reached up to the ppb level with high anti-interference ability in aqueous phase, and the effective detection of antibiotics had been theorized by D. Functional Theory (DFT) calculation for energy bands of H3L and antibiotics, which revealed that the cooperation influence on photo-induced electron transfer (PET) process and fluorescence inner filter effect (IFE) made CHL show more sensitive luminescence responses than other exptl. antibiotics. Moreover, because of its specific interactions with analytes and relatively high porosity, the pre-enrichment makes the antibiotic fuller contact and interact with the framework, which improves the overall sensing efficiency toward CHL appreciably. Stemming from the abuse, antibiotics have been considered as the great threat to the health of human race and the sustainable development of society. Therefore, it is extremely important to achieve new technol. to detect and absorb antibiotics residues in water. This work proves that metal-organic framework complexes can conform the performance of detecting and removing antibiotic in aqueous environment, that emphasizes the application of luminescent MOFs in contaminant monitoring and removing. This study involved multiple reactions and reactants, such as 3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6Name: 3,5-Di(1H-imidazol-1-yl)pyridine).
3,5-Di(1H-imidazol-1-yl)pyridine (cas: 1374155-84-6) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Name: 3,5-Di(1H-imidazol-1-yl)pyridine
