Due to serious environmental pollutions, the detection of hazardous and explosive nitro-aromatic compounds using metal-organic frameworks (MOFs) have been a promising research field in the current scenario. Here, we report a new fluorescent MOF, [Zn2(TCPE)(tta)2]·2DMF·4H2O·2Me2NH2 + (HNU-34, H4TCPE = 1,1,2,2-tetra(4-carboxylphenyl)ethylene, 1H-tta = 1H-tetrazole) which possesses a 3D configuration and 1D channels along the c-axis. It can serve as a luminescence sensor for the detection of nitrophenol explosives through different quenching effects, especially for the mononitrophenol and dinitrophenol. The detection limits of 2,6-dinitrophenol and trinitrophenol are 29.45 nM and 36.15 nM, respectively, which are among the high level of the reported MOF sensors, especially for DNP.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1351279-73-6, help many people in the next few years.Formula: C30H20O8

A family of enantiomerically pure ligands based on the cyclobutenedione structure, and containing either an enantiomerically pure amino alcohol or a diamine as the chiral element, has been synthesized. As first examples of their application, these versatile and modularly constructed ligands have been tested in the transfer hydrogenation of acetophenone and in the reduction using borane of this same substrate.

A set of 4?-substituted 2,2?:6?,2?-terpyridines has been synthesized in a one-pot procedure under environmentally friendly reaction conditions using PEG and aqueous ammonia as solvents. This procedure features a short synthetic route, short reaction times, easy work-up, and good yields in comparison to conventional methods. The crystallographic data reveal the influence of the 4?-aryl substituent on the molecular structure and pi-stacking behavior of the respective terpyridines. Georg Thieme Verlag Stuttgart.

Novel chiral bidentate P,N-containing ligands have been easily synthesized by Schiff-base condensation of o-(diphenylphosphino)benzaldehyde and modified chiral diamine, (R,R)-2-(2,5-dimethyl-pyrrol-1-yl)-cyclohexylamine, further reduction with NaBH4. The chiral ruthenium(II) complex could be successfully prepared from the reaction between chiral bidentate aminophosphine ligand and RuCl2(PPh3)3. The chiral bidentate P,N-containing ligands and ruthenium(II) complex were fully characterized by NMR, IR, HRMS and single-crystal X-ray diffraction studies. In the presence of KOH, the asymmetric transfer hydrogenation (ATH) of various ketones catalyzed by the chiral ruthenium(II) complex proceeded smoothly under mild conditions, affording corresponding chiral secondary alcohols with up to 99% conversion and up to 60% ee. Additive such as NH4I was found to be helpful to promoting the enantioselectivity.

Schiff bases and their metal complexes in the mixtures of ionic liquid (IL) + organic solvent have shown great potential in attractive oxidation catalytic processes. The efficiency of such a process is strongly dependent on the various molecular interactions occurring between components. Thermodynamic properties of these systems can provide valuable information about structural interactions. Therefore, in this work, the interactions of the IL 1-hexyl-3-methylimidazolium chloride ([HMIm]Cl) with Schiff bases in organic solvents were studied through the measurements of density, viscosity, and electrical conductivity. The effect of solvent on the interactions was examined by the solutions of IL + BPIC Schiff base + solvent (C2H6O-C3H8O-C4H10O). Moreover, the influence of Schiff base ligand and Schiff base complex structures was probed by the solutions of IL + DMA + ligand (salcn/salpr/salen) and IL + DMA + complex (VO(3-OMe-salen)/VO(salophen)/VO(salen)), respectively. Using the experimental data, some important thermodynamic properties, such as standard partial molar volume (Vf,IL0), experimental slope (Sv), viscosity B-coefficient, solvation number (B/Vf,IL0), and limiting molar conductivity (Lambda0) were calculated and discussed in terms of solute-solvent (IL-DMF/alcohol) and solute-cosolute (IL-Schiff base) interactions.

Acid-base properties of methyl orange, bromocresol green, bromophenol blue, and bromothymol blue were thoroughly investigated in the past due to their application as colorimetric pH indicators. However, it is still unknown how these properties change upon the supramolecular host-guest interactions. Owing to the growing interest in using supramolecular host-guest interactions to reach expected modification of various physicochemical properties of guests, we decided to address this question in the present article. We estimated the shifts of pKa values induced by diverse hosts (cyclodextrins, cucurbiturils, calixarenes, micelles, and serum albumin) and performed a thermodynamic analysis of the selected systems. To make a deeper insight, we confronted the aforementioned dyes with the other kinds of molecules studied by us in the past. In overall, the results obtained demonstrate a large multiplicity of possible pKa behaviors, their poor predictability, and the existence of subtle structure-acidity relationships. In addition, we observed three thermodynamically different mechanisms of pKa alteration. Therefore, more studies are needed to bring closer the promising perspective of a programmable acidity?s tuning. Our methodology was based on capillary electrophoresis (CE) applied in two parallel variants: a classical method based on the fitting of a nonlinear function, and an alternative two-value method (TVM), which requires over twice less measurements to estimate pKa. To identify the optimal approach for further studies, both methods were comprehensively compared and discussed based on the RGB additive color model, a user-friendly scale that integrates three primary aspects of an analytical method: analytical performance, green chemistry, and practicality.
