Retracted: Luminescent In(III)‐based coordination polymer for selectively sensing Cr₂O₇²⁻, antibacterial and anti‐inflammatory effect on the infectious abortion

Abstract

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.

Amino Acid Groups Enable Electrosynthesized Polyfluorenes to Specifically Recognize Cr2O72–

“…In the environment, Cr 2 O 7 2– can be traced in industrial waste or natural waters. − In order to effectively remove Cr 2 O 7 2– , the efficient detection and recognition of Cr 2 O 7 2– is an indispensable step. At present, fluorescent sensors for detecting Cr 2 O 7 2– based on various materials have been reported, such as metal–organic frameworks, − nanoclusters, , carbon dots, − quantum dots, , ionic liquids, small organic molecules, coordination polymers, , and CPs . Until now, there are several reports about Cr 2 O 7 2– based on CPs.…”
