Protonation sites and hydrogen bonding in mono-hydrobromide salts of two N,4-diheteroaryl 2-aminothiazoles

The synthesis and structural characterization of N-(6-methoxypyridin-3-yl)-4-(pyridin-2-yl)thiazol-2-amine mono-hydrobromide monohydrate (3) and N-(6-methoxypyridin-3-yl)-4-(pyrazin-2-yl)thiazol-2-amine mono-hydrobromide 0.35 methanol solvate (4) are reported. The crystal structures of 3 (monoclinic, space group P2(1)/n, Z = 4) and 4 (monoclinic, space group, C2/c, Z = 8) feature N,4-diheteroaryl 2-aminothiazoles showing similar molecular conformations but different sites of protonation and thus distinctly different intermolecular hydrogen bonding patterns. In 3, N-amine-HMIDLINE HORIZONTAL ELLIPSISBr-, N-pyridine(+)-HMIDLINE HORIZONTAL ELLIPSISOwater, and O-water-HMIDLINE HORIZONTAL ELLIPSISBr- hydrogen bonds link protonated N-(6-methoxypyridin-3-yl)-4-(pyridin-2-yl)thiazol-2-amine and water molecules and bromide anions into a three-dimensional hydrogen-bonded network, whereas intermolecular N-methoxypyridine(+)-HMIDLINE HORIZONTAL ELLIPSISNpyrazine hydrogen bonds result in hydrogen-bonded zigzag chains of protonated N-(6-methoxypyridin-3-yl)-4-(pyrazin-2-yl)thiazol-2-amine molecules in 4.

Synthesis, photophysical evaluation, and computational study of 2-methoxy-and 2-morpholino pyridine compounds as highly emissive fluorophores in solution and the solid state

Two 2-pyridone tautomeric analogs, methoxypyridine 4 and N-methylpyridone 5, were synthesized, and their spectroscopic properties were investigated both experimentally and computationally. A detailed photophysical study reveals that 4 shows high fluorescence quantum yields not only in chloroform but also in ethanol, and the strong fluorescence in solution might be attributed to the enol form (pyridine) of the 2-pyridone. Furthermore, we designed and synthesized novel 2-substitued pyridines to achieve more intense emissions in both solution and the solid state. Substituent modification with phenylsulfonyl, morpholino, and 4-diethylamino groups greatly affected the fluorescence properties, and methoxypyridine 7 and morpholinopyridine compound 8 showed fluorescence in various solvents (Phi = 0.59-0.95) and the solid state (Phi = 0.12-0.15). A hypsochromic shift in the emission maximum wavelength and strong fluorescence in the solid state (Phi = 0.39) were observed for dimorpholinopyridine 9. Morpholinopyridine 11 showed intense fluorescence in all nonpolar and polar solvents. Systematic time-dependent density functional theory calculations were performed for the compounds whose electronic and fluorescent maxima were computationally reproduced with good agreement to those from experiment. In detail, the drastic difference in the emission intensity between 4 and 5 in solution was successfully explained using CASSCF calculations, which revealed the presence of conical intersections between the ground and the excited states.

Designing benzothiadiazole based non-fullerene acceptors with high open circuit voltage and higher LUMO level to increase the efficiency of organic solar cells

Non-fullerene acceptors have been widely used to fabricate the organic solar cells (OSCs) with enhanced photovoltaic efficiency owing to their superior and valuable properties over fullerene acceptors. In this regard, an effort has been made to design four new (A2-pi-A1-pi-A2) type acceptor molecules (MOL1 , MOL2 , MOL3 , and MOL4) to study their optoelectronic properties and their application in improving the efficiency of OSCs. These designed molecules contain benzothiadiazole (BT) core unit which has been bridged up through (E)-2-(prop-1-enyl)thiophene with four different end capped acceptors namely 2-((5-vinylthiophen-2-yl)methylene)malononitrile (MOL1), methyl 2-cyanoacrylate (MOL2), 3-methyl-5-methylenethiazolidine-2,4-dione (MOL3), 4-vinyl- [1,2,5]thiadiazolo[3,4-c]pyridine (MOL4). Using density functional theory (DFT) and time-dependent density functional theory (TD-DFT) optoelectronic properties have been analyzed and compared with renowned reference 4,7-bis(4-(N-hexyl-phthalimide)vinyl) benzo[c]1,2,5-thiadiazole (PI-BT as RCAM). Appropriate frontier molecular orbitals (FMO) diagrams for each molecule have been drawn to study charge transfer. Amongst all four molecules, MOL1 with narrow bandgap is the best red-shifted compared to RCAM (545.02 nm). Furthermore, exciton binding energy, electron and hole mobility is theoretically calculated. Results showed the MOL4 with the highest VOC (3.35 V) and lowest Eb for best device efficiency. Electron and hole mobility calculations predicted these designed molecules to be better hole transporters compared to RCAM. Owing to their remarkable results these designed acceptor molecules are counted in to enhance the performance and efficiency of devices.

Triple-Bond Directed Csp(2)-N Bond Formation with N-Fluorobenzenesulfonimide as Aminating Source: One-Step Transformation of Aldehydes into Amines

A metal-free, versatile triple-bond directed approach for the decarbonylative C-H amination of ortho-alkynyl quinoline/pyridine aldehydes using N-fluorobenzenesulfonimide as nitrogen source under mild reaction conditions has been described. The designed reaction strategy was triggered by trapping of fluorine by base with subsequent attack of bis(phenylsulfonyl)-lambda(2)-azane on the carbonyl carbon of a heterocycle, which was gradually converted into the corresponding amine through a Curtius type rearrangement. This protocol provides a one-step approach for the conversion of aldehydes into amines in good yields. The synthesized amines were successfully transformed into biologically important pyrroloquinolines/pyridines.

Metal-Organic Cages with Missing Linker Defects

We present here the controlled synthesis of defective coordination cages by employing steric hindrance of organic linkers to manipulate coordination modes of the assembled metal ions. Three chiral 1,1 ‘-bi-2-naphthol (BINOL) derived bis-tridentate ligands L-1-L-3 with pyridine-2,6-dicarboxamides (pcam) chelating moieties are therefore designed and synthesized, among which L-3 has a smaller steric hindrance on the coordinating sites relative to the other two linkers. Complexes of L-1 and L-2 with lanthanides afford the irregular Ln(8)(L-1)(10) hexahedra with two missing edges and Ln(4)(L-2)(5) tetrahedra with one missing edge, respectively, both of which contain a 1:1 mixture of Ln(pcam)(2) and Ln(pcam)(3). In contrast, complex of L-3 produces the regular twisted Ln(6)(L-3)(9) trigonal prisms without missing edges that contain only Ln(pcam)(3) vertices. The defective cage has more freedom to adjust its structural conformation, affording adaptable cavity to accommodate a range of guest molecules with sizes comparable or much larger than the cavity portals.

Conjugates of Gold Nanoparticles and Antitumor Gold(III) Complexes as a Tool for Their AFM and SERS Detection in Biological Tissue

Citrate-capped gold nanoparticles (AuNPs) were functionalized with three distinct antitumor gold(III) complexes, e.g., [Au(N,N)(OH)(2)][PF6], where (N,N)=2,2′-bipyridine; [Au(C,N)(AcO)(2)], where (C,N)=deprotonated 6-(1,1-dimethylbenzyl)-pyridine; [Au(C,N,N)(OH)][PF6], where (C,N,N)=deprotonated 6-(1,1-dimethylbenzyl)-2,2′-bipyridine, to assess the chance of tracking their subcellular distribution by atomic force microscopy (AFM), and surface enhanced Raman spectroscopy (SERS) techniques. An extensive physicochemical characterization of the formed conjugates was, thus, carried out by applying a variety of methods (density functional theory-DFT, UV/Vis spectrophotometry, AFM, Raman spectroscopy, and SERS). The resulting gold(III) complexes/AuNPs conjugates turned out to be pretty stable. Interestingly, they exhibited a dramatically increased resonance intensity in the Raman spectra induced by AuNPs. For testing the use of the functionalized AuNPs for biosensing, their distribution in the nuclear, cytosolic, and membrane cell fractions obtained from human lymphocytes was investigated by AFM and SERS. The conjugates were detected in the membrane and nuclear cell fractions but not in the cytosol. The AFM method confirmed that conjugates induced changes in the morphology and nanostructure of the membrane and nuclear fractions. The obtained results point out that the conjugates formed between AuNPs and gold(III) complexes may be used as a tool for tracking metallodrug distribution in the different cell fractions.

Metabolic engineering of Rhodococcus jostii RHA1 for production of pyridine-dicarboxylic acids from lignin

Genetic modification of Rhodococcus jostii RHA1 was carried out in order to optimise the production of pyridine-2,4-dicarboxylic acid and pyridine-2,5-dicarboxylic acid bioproducts from lignin or lignocellulose breakdown, via insertion of either the Sphingobium SYK-6 ligAB genes or Paenibacillus praA gene respectively. Insertion of inducible plasmid pTipQC2 expression vector containing either ligAB or praA genes into a Delta pcaHG R. jostii RHA1 gene deletion strain gave 2-threefold higher titres of PDCA production from lignocellulose (200-287 mg/L), compared to plasmid expression in wild-type R. jostii RHA1. The ligAB genes were inserted in place of the chromosomal pcaHG genes encoding protocatechuate 3,4-dioxygenase, under the control of inducible P-icl or P-nitA promoters, or a constitutive P-tpc5 promoter, producing 2,4-PDCA products using either wheat straw lignocellulose or commercial soda lignin as carbon source. Insertion of Amycolatopsis sp. 75iv2 dyp2 gene on a pTipQC2 expression plasmid led to enhanced titres of 2,4-PDCA products, due to enhanced rate of lignin degradation. Growth in minimal media containing wheat straw lignocellulose led to the production of 2,4-PDCA in 330 mg/L titre in 40 h, with>tenfold enhanced productivity, compared with plasmid-based expression of ligAB genes in wild-type R. jostii RHA1. Production of 2,4-PDCA was also observed using several different polymeric lignins as carbon sources, and a titre of 240 mg/L was observed using a commercially available soda lignin as feedstock.

Pyridinic Nanographenes by Novel Precursor Design

In this work we present the solution-synthesis of pyridine analogues to hexa-peri-hexabenzocoronene (HBC)-which might be called superpyridines-via a novel precursor design. The key step in our strategy was the pre-formation of the C-C bonds between the 3/3′ positions of the pyridine and the adjacent phenyl rings-bonds that are otherwise unreactive and difficult to close under Scholl-conditions. Apart from the synthesis of the parent compound we show that classical pyridine chemistry, namely oxidation, N-alkylation and metal-coordination is applicable to the pi-extended analogue. Furthermore, we present basic physical chemical characterizations of the newly synthesized molecules. With this novel synthetic strategy, we hope to unlock the pyridine chemistry of nanographenes.

Solution X-Ray Absorption Spectroscopy (XAS) for Analysis of Catalytically Active Species in Reactions with Ethylene by Homogeneous (Imido)vanadium(V) Complexes-Al Cocatalyst Systems

Solution V K-edge XANES (X-ray absorption near edge structure) and EXAFS (extended X-ray absorption fine structure) analysis of vanadium(V) complexes containing both imido ligands and anionic ancillary donor ligands (L) of type, V(NR)(L)X-2 (R = Ar, Ad (1-adamantyl); Ar = 2,6-Me2C6H3; X = Cl, Me, L = 2-(ArNCH2)C5H4N, OAr, WCA-NHC, and 2-(2′-benzimidazolyl)pyridine; WCA-NHC = anionic NHCs containing weak coordinating B(C6F5)(3)), which catalyze ethylene dimerization and/or polymerization in the presence of Al cocatalysts, has been explored. Different catalytically actives species with different oxidation states were formed depending upon the Al cocatalyst (MAO, Me2AlCl, (AlBu3)-Bu-i, etc.) and the anionic ancillary donor ligand employed. The method is useful for obtainment of the direct information of the active species (oxidation state, basic framework around the centered metal) in solution, and for better understanding in catalysis mechanism and organometallic as well as coordination chemistry.
