A Water‐Stable Terbium(III)–Organic Framework as a Chemosensor for Inorganic Ions, Nitro‐Containing Compounds and Antibiotics in Aqueous Solutions

Abstract

Effective detectiono fo rganic/inorganic pollutants, such as antibiotics, nitro-compounds, excessive Fe 3 + and MnO 4 À ,i sc rucial for human health and environmental protection. Here, an ew terbium(III)-organic framework, namely [Tb(TATAB)(H 2 O)]·2H 2 O( Tb-MOF,H 3 TATAB = 4,4',4''-s-triazine-1,3,5-triyltri-m-aminobenzoic acid), was assembled and characterized.The Tb-MOF exhibits awater-stable 3D bnn framework. Due to the existence of competitive absorption, Tb-MOF has ahigh selectivity for detecting Fe 3 + ,MnO 4 À ,4-niro-phenola nd nitroimidazole( ronidazole, metronidazole, dimetridazole, ornidazole) in aqueous through luminescent quenching. The results suggest that Tb-MOF is as imple and reliable reagent with multiple sensor responses in practical applications. To the best of our knowledge, this work represents the first Tb III -based MOF as an efficient fluorescent sensorf or detecting metal ions, inorganic anions, nitro-compounds, and antibiotics simultaneously.[a] J.

A Highly Stable (4, 8)‐Connected Tb‐MOF Exhibiting Efficiently Luminescent Sensing towards Nitroimidazole Antibiotics

“…To the best of our knowledge, only five complex‐derived probes for MDZ and DTZ have been reported by far (Table ). The emission signal of these complexes for sensing originates either from ligand‐centered charge transfer for transitional metal complexes or from ligand‐sensitized characteristic emission of Ln‐MOFs . In addition to the comparable K SV and LOD values, Tb‐MOF has the superior advantages of the smallest dose (0.1 mg · mL –1 vs. 0.5–1.5 mg · mL –1 ) and wider response range (0–132 μM vs. 0–80 μM) than those known sensors.…”

Synthesis, structure, photophysical properties, and energy transfer mechanism of an erbium–mercury compound

“…It is well known that lanthanide metals possess more complicated electronic conformations than those of transition metals and so lanthanide metal compounds generally exhibit attractive physicochemical performances such as photoluminescence, sensors, magnetism, medicine, and catalysis. [1][2][3][4][5][6][7][8][9] Therefore, lanthanide metal compounds have attracted increasing interest from materials and chemical scientists. Up to date, these scientists have carried out many studies on lanthanide metal compounds with different organic ligands such as aromatic carboxylic acids and heterocyclic compounds.…”

Synthesis, Crystal Structure and Luminescent Properties of a 3D Mg(II)−Sm(III) Heterometallic Coordination Polymer Containing 20‐member Water Clusters

“…[28][29][30] Until now, some neutral water oligomers, including discrete rings and clusters contained in CPs or MOFs, have been well-studied by X-ray diffraction methods. [21,31] A considerable part of such CPs or MOFs is based on functional components composed of different aromatic monocarboxylic acid and polycarboxylic acids. Pyridine-2,6dicarboxylic acid (H 2 pydc) is a well-known versatile N,O-chelator in coordination chemistry, which can form abundant mononuclear and polynuclear complexes, and is also recognized as a structural component for designing various coordination polymers, metal-organic frameworks and supramolecular.…”
