Asymmetrically substituted 5,5 ”-diaryl-2,2 ‘:6 ‘,2 ”-terpyridines as efficient fluorescence turn-on probes for Zn2+ in food/cosmetic samples and human urine

The present article describes the synthesis of new asymmetrically substituted 5,5 ”-diaryl-2,2 ‘:6 ‘,2 ”-terpyridines as prospective chemosensors/probes for the fluorescence turn-on detections of Zn2+. After the fluorescence titration experiments two most representative terpyridines, namely 4-phenyl-1-(6-(4-p-tolyl-6,7-dihydro-5H-cyclopenta[c]-pyridin-1-yl)pyridin-2-yl)-6,7-dihydro-5H-cyclopenta[c]pyridine and 5-phenyl-5 ”-p-tolyl2,2 ‘:6 ‘,2 ”-terpyridine were selected based on high binding constant up to 10(6) M-1 for the 1:2 (Zn2+ : ligand) complexes along with the limits of detection (LOD) as low as similar to 0.1 x 10(-9) M. These ligands have been further used as fluorescence probes for the qualitative and quantitative detection of Zn2+ in real samples, such as food/ cosmetic samples and human urine. For all the samples, these probes exhibited an intensive fluorescence enhancement via the effective transduction LE-TICT-switching signal. The stoichiometry and structure of the Zn2+ complexes were supported by DFT calculations and H-1 NMR experiments.

Mechanical vs Electronic Strain: Oval-Shaped Alkynyl-Pt(II)-Phosphine Macrocycles

Pyridine-terminated molecular rods and either (i) the cis-(dppp)(I)Pt(C C-triptycene-C C)Pt(I)(dppp) rod or (ii) the trans-(PEt3)(2)(I)Pt(C C-biphenyl-C C)Pt(I)(PEt3)(2) rod assemble into macro-cycles, characterized by NMR, ESI-IMS, and in two cases also single-crystal X-ray diffraction. The former form rectangles with bidentate phosphine-containing cis-coordinated Pt(II)-alkyne corners. In the latter, the preference of the Pt centers for a trans configuration overrules the preference of the triple bonds for linearity and NMR shows that they have oval structures with alternating bent rod and bent trans (C C)Pt(PEt3)(2)(C C) components, in agreement with density functional theory calculations.

Crystal structure of pyridinium tetraisothiocyanatodipyridinechromium(III) pyridine monosolvate

In the crystal structure of the title compound, (C5H6N)[Cr(NCS)(4)(C5H5 N)(2)]center dot-C5H5N, the Cr-III ions are octahedrally coordinated by four N-bonding thiocyanate anions and two pyridine ligands into discrete negatively charged complexes, with the Cr-III ion, as well as the two pyridine ligands, located on crystallographic mirror planes. The mean planes of the two pyridine ligands are rotated with respect to each other by 90 degrees. Charge balance is achieved by one protonated pyridine molecule that is hydrogen bonded to one additional pyridine solvent molecule, with both located on crystallographic mirror planes and again rotated by exactly 90 degrees. The pyridinium H atom was refined as disordered between both pyridine N atoms in a 70:30 ratio, leading to a linear N-H center dot center dot center dot N hydrogen bond. In the crystal, discrete complexes are linked by weak C-H center dot center dot center dot S hydrogen bonds into chains that are connected by additional C-H center dot center dot center dot S hydrogen bonding via the pyridinium cations and solvent molecules into layers and finally into a three-dimensional network.

Antiproliferative evaluation and supramolecular association involving electrostatically enhanced pi-pi interaction in isostructural coordination solids of Mn(II), Co(II) and Zn(II) chlorobenzoates: Experimental and theoretical studies

Three new isostructural coordination solids viz. [Co(3-CNpy)(2)(2-ClBz)(2)(H2O)(2)] (1), [Mn(3-CNpy)2(2-ClBz)(2)(H2O)(2)] (2) and [Zn(3-CNpy)(2)(2-ClBz)(2)(H2O)(2)] (3) (3-CNpy=3-cyanopyridine, 2-ClBz=2-chlorobenzoate) have been synthesized from purely aqueous media and characterized by X-ray crystal structure analysis, FT-IR, electronic spectra and TGA. Several non-covalent hydrogen bonding interactions of the types O-H center dot center dot center dot O, C-H center dot center dot center dot O, C-H center dot center dot center dot N, C-H center dot center dot center dot Cl and pi-pi stacking contacts build up the supramolecular networks in the crystal structures. Electrostatically enhanced p-p interactions are observed in 1-3 between the phenyl rings of 2-ClBz and pyridine ring of 3-CNpy of the monomeric units of the complexes. We have used the molecular DFT calculations to evaluate energetically the strength of these contacts and also to analyze the effect of the metal on the interaction energies. The energetic features of the H-bonding and pi-stacking interactions for 1-3 reveal that the H-bonded assembly is more favorable than the pi-stacked contacts. The electrostatically enhanced energy of the pi-stacking interactions is stronger than that usually observed for pi-stacking interactions involving arenes. The cytostatic potential of all complexes have been studied in Dalton’s lymphoma (DL) cell line by MTT assay, apoptosis assay and further corroborated with molecular docking simulation. The complexes exhibit cytotoxicity (similar to 25-30%) through apoptotic cell death with negligible cytotoxicity (similar to 5-10%) in normal PBMC cells. In silico-docking techniques have been performed with apoptosis regulator protein BCL-2 for the identification of critical amino acids and their possible binding affinity with the synthesized complexes. The pharmacophore features based on structure activity relationship (SAR) of the complexes have been identified and the study reveal that the features viz., hydrophobic, aromatic, positive ionizable, negative ionizable, H-bond donor and acceptor and halogen bond donor properties play important role for the biological activities of the complexes.

Heteropolyacid (H3PW12O40)-impregnated mesoporous KIT-6 catalyst for green synthesis of bio-diesel using transesterification of non-edible neem oil

Mesoporous Ia3d cubic structured KIT-6 support was prepared by hydrothermal strategy and heteropoly acid content (10, 20 and 30%) was stacked on KIT-6 by wet-impregnation technique. The synthesized catalysts were characterized by XRD, N-2-sorption, NH3-TPD, ATFT-IR, TEM and SEM-EDAX analyses. Acid properties of the supported catalysts were investigated by pyridine-adsorbed ATFT-IR and NH3-TPD, respectively. Poly-anion coordination present in the catalyst was confirmed by the DRS-UV spectrum. The dispersion of heteropoly acid on the catalyst surface was observed by TEM analysis. Also, the presence of the elements such as W and P on the catalyst and its morphology were represented by the HRSEM-EDAX technique. The catalytic activity of HPWA/KIT-6 was investigated by the transesterification of neem oil with methanol. Among the different wt% catalyst, 20% catalyst showed highest neem oil conversion and selectivity at an optimized reaction temperature of 60 degrees C. Further, the spent catalyst was recovered and recycled three times, and it showed activity losses of less than 4%.

Electrostatically Driven Guest Binding in Self-Assembled Molecular Network of Hexagonal Pyridine Macrocycle at the Liquid/Solid Interface: Symmetry Breaking Induced by Coadsorbed Solvent Molecules

We present here the construction of a self-assembled two-dimensional network at the liquid/solid interface using a hexagonal pyridine macrocycle which binds an organic cation in its intrinsic porous space by electrostatic interactions. For this purpose, a hexagonal pyridinylene-butadiynylene macrocycle (PyBM) having six octyloxymethyl groups, PyBM-C8, was synthesized. As guests, tropylium (Tr) tetrafluoroborate and trioxatriangulenium (TOTA) hexafluorophosphate were used. In this study, we focused on (i) the network patterns of PyBM-C8 which change in response to its concentration and (ii) the position of the guest immobilized in the porous space of the macrocycle. Scanning tunneling microscopy (STM) observations at the interface of 1,2,4-trichlorobenzene (TCB) and highly oriented pyrolytic graphite (HOPG) revealed that PyBM-C8 formed four different polymorphs, oblique, loose hexagonal, linear, and rectangular, depending on the solute concentration and annealing treatment. Solvent TCB molecules are likely coadsorbed to not only the intrinsically porous space of PyBM-C8 (internal TCB) but also the space outside of the macrocycle between its alkyl chains (external TCB) in most of the cases. Upon adding the guest cation, whereas small Tr was not visualized in the pore due to size mismatching, larger TOTA was clearly observed in each pore. In addition, based on high-resolution STM images of the rhombus packing pattern of PyBM-C8, we revealed experimentally that TOTA was placed at an off center position of the deformed hexagonal macrocyclic core in the rhombus pattern. On the basis of the molecular mechanics calculations, we hypothesize that the off-center location of TOTA is due to deformation of the hexagonal macrocycle through interaction with two external TCB molecules located at opposite edges of the macrocyclic core. Symmetry breaking of the macrocyclic host framework induced by coadsorbed surrounding solvent molecules thus plays a significant role in host-guest complexation at the liquid/solid interface.

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 350-03-8 help many people in the next few years. Name: 1-(Pyridin-3-yl)ethanone.
