“…After calculation, the K SV slope is 6555070 M –1 , which is 565 times more than that of dimethyl sulfoxide/functional fluorescent aramid fiber (11600 M –1 ) utilized for Cr 2 O 7 2– sensing in water while 95 times more than that of fluorescent carbon dot (69000 M –1 ) utilized to identify Cr 2 O 7 2– in water. K SV is also better than a number of other benchmark sensors based on MOF and Eu 3+ @MIL‐124 (60340 M –1 ) utilized for sensing Cr 2 O 7 2– in the water . Compound 1 is highly sensitive along with selective for Cr 2 O 7 2– detection within the solution of water.…”

A novel water-stable metal-organic framework based on In(III), namely, [In 3 (btta) 2 -(OH) 3 (H 2 O)]⋅(DMA) 2 (1, DMA = N,, constructed from a novel ligand (2E,2 ′ E,2 ″ E)-3,3 ′ ,3 ″ -(benzene-1,3,5-triyl)triacrylic acid (H 3 btta), was obtained by a solvothermal reaction and structurally characterized by X-ray diffraction of single crystal along with elemental analysis. Owing to its high porosity and insensitive luminescent emission at room temperature, it was studied as a light-emitting sensor for detecting toxic Cr 2 O 7 2− anion in water, which shows high selectivity and sensitivity. To solve the bacterial problem, the protective effect of the compound against bacterial infection after missed abortion was evaluated. In the in vivo model, after the treatment with the compound, the clonal formation unit (CFU) in the uterine tissue was evaluated, and the animal weight was measured and recorded. In addition to this, the level of IL-18, C-reactive protein, TNF-, as well as IL-1 within the infectious tissues was detected by the ELISA method. Pose scoring software and molecular docking showed that the compound might bind to the NF-B protein, and this might offer a latent regulatory mechanism for the compound.

“…The quenching percentage is 98.07% when the concentration of Fe 3+ cation is 0.500 mM, and the quenching percentage is 92.54% when the concentration of the Cr 2 O 7 2À anion is 0.400 mM. The quenching efficiency can be evaluated by the the Stern-Volmer (SV) equation: I 0 /I = 1 + K SV [M] (I 0 and I in the Stern-Volmer equation represent the lumines-cence intensities before and after adding detected ions, K SV is the SV quenching constant and [M] is the concentration of the detected ions) (Chen et al, 2017). As shown in Fig.…”

Ni II MOF (I) shows a 4-connected 3D framework with point symbol 6 6 , but is not a typical dia network. Zn II MOF (II) displays a two-dimensional 4 4 -sql network with onedimensional water chains penetrating the grids along the c direction. The solidstate photoluminescence analysis of (II) was performed at room temperature and the MOF exhibits highly selective sensing toward Fe 3+ and Cr 2 O 7 2À ions in aqueous solution. research papers Acta Cryst.

“…In generally, the luminescence quenching detection of analytes based on Ln‐MOFs can proceed via the following mechanisms: i) crystallographic alteration/disintegration induced by the interaction/ion‐exchange process between MOFs and analytes; ii) effective overlap of the ligand band with adsorption of analytes, i.e., the so‐called Förster mechanism can lead to a sort of competitiveness between the MOFs excitation and the analyte adsorption; iii) weak interactions between MOFs and analytes . The last two mechanisms are more practical, however, still rare for the detection of Fe 3+ and Cr VI anions.…”

Twon ew three-dimensional (3D) Ln III metal-organic frameworks (MOFs)w ere designed and successfully obtained via as olvothermalr eaction between lanthanide(III) nitrates and as emi-flexiblec arbazole tetracarboxylate acid linker as ah igh-performancec hromophore. 1 and 2 possess porous 3D networks with channels along the a axis, and more importantly,t hey show ah ighly sensitivea nd selective fluorescence quenching response to Fe 3 + and Cr VI anions. The sensing mechanism investigation revealed that the weak interactions of Fe 3 + with nitrogen atoms of carbazole and deprotonated carboxylic acids protruding into the pores of MOFs quenched the luminescence of 1 and 2 effectively. In addition, the competition absorption also playeda ni mportant role in the luminescence quenchingd etection of Fe 3 + based on 1,a nd Cr VI anionsb ased on 1 and 2.T herefore, 1 and 2 represent an alternative example of regenerable luminescence based sensors fort he quantitative detection of Fe 3 + and Cr VI anions.
