Heteroarene-linked bis(N-heterocyclic carbenes) constitute an important family of ligands in transition metal chemistry and homogeneous catalysis. These ligands are used as multidentate ligands for the construction of mononuclear and multinuclear complexes that show unique physical properties and that are efficient catalysts for many organic transformations. A number of transition metal complexes of heteroarene-linked bis(N-heterocyclic carbene) ligands have been synthesized and structurally characterized in recent decades. In this review, we summarize the recent developments in metal complexes supported by heteroarene-linked bis(N-heterocyclic carbene) ligands and their applications. The ligands and their complexes are categorized by the linkers between the two NHCs, such as pyridine, bipyridine, phenanthroline, naphthyridine, pyrazole, thiophene, and pyridazine.

A new rhodamine-based derivative bearing a naphthyridine group (compound 1) was synthesized as a colorimetric and fluorescent off-on chemosensor for Cu2+ in aqueous solutions. The sensing behaviors of 1 toward various metal ions in neutral aqueous solutions were investigated by absorption and fluorescence spectroscopies. Compound 1 is found to exhibit a significant increase in absorbance at 561 nm and an amplified fluorescence at 590 nm toward Cu2+ in a selective, sensitive and rapid manner. The quantification of Cu2+ by 1 using an absorption spectroscopy method was satisfactory in the linear working range 0.9-10 mu M, with a detection limit of 5.4 x 10(-8) M for Cu2+ and good tolerance of other metal ions. Upon addition of Cu2+, the spirolactam ring (colorless and nonfluorescent) of 1 was opened to ring-opened amide (red color and fluorescent) and a 1:1 stoichiochemetry for the 1-Cu2+ complex was formed with an association constant of 1.57 x 10(4) M-1.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 3147-75-9, in my other articles. Recommanded Product: 3147-75-9.

Three novel Zn(II) complexes, [ZnCl2(qz)(2)] (1), [ZnCl2(1,5-naph)](n) (2) and [ZnCl2(4,7-phen)(2)] (3), where qz is quinazoline, 1,5-naph is 1,5-naphthyridine and 4,7-phen is 4,7-phenanthroline, were synthesized by the reactions of ZnCl2 and the corresponding N-heterocyclic ligand in 1:2 molar ratio in ethanol at ambient temperature. The characterization of these complexes was done by NMR, IR and UV-Vis spectroscopy, and their crystal structures were determined by single-crystal X-ray diffraction analysis. Complexes 1 and 3 are mononuclear species, in which Zn(II) ion is tetrahedrally coordinated by two nitrogen atoms belonging to two qz or 4,7-phen ligands, respectively, and by two chloride anions, while complex 2 is a 1D coordination polymer that contains 1,5-naph as bridging ligand between two metal ions. In agar disc-diffusion assay, complexes 1-3 manifested good inhibitory activity against two investigated Candida strains (C. albicans and C. parapsilosis), while not inducing toxic effects on the healthy human fibroblast cell line (MRC-5). This activity was not fungicidal, as revealed by the broth microdilution assay, however complex 3 showed the ability to modulate Candida hyphae formation, which is an important process during infection and showed significant synergistic effect with clinically used antifungal polyene nystatin.

Small molecule organic semiconductors have well-defined structures and can be used in place of polymers which often show batch-to-batch variation. Many different electron-rich donor and electron-deficient acceptor units have been used to design materials with reduced HOMO-LUMO gaps and improved mobilities. Here we introduce a novel acceptor unit, 1-dodecyl-6-dodecoxynaphthyridine-2-one. This acceptor unit has been used in the synthesis of two novel compounds, with thiophene and 2,1,3-benzothiadiazole (BT) cores. The BT-containing compound shows a narrower HOMO-LUMO gap, broad solid-state absorption and has been applied to organic field-effect transistors, showing a mobility of 0.022 cm(2) V-1 s(-1) after optimisation of devices using self-assembled monolayers.

Novel mero/bis-mero cyanine dyes based on N-bridgehead imidazo[1,2-g] quinolino[2,1-a][2,6] naphthyridine have been synthesized and characterized to evaluate intramolecular charge transfer (ICT) effect on the energy gap (E0-0). The UV-vis and emission spectral studies revealed that dyes are absorbed in the region of lambda(max) 485-577 nm and emitted at 567-673 nm. Their solvatochromic behavior in solvents of various polarities, CCl4, C6H6, H2O, CHCl3, acetone, and DMF, was studied to emphasize the effect of solvent polarity on the absorption maxima, molar extinction coefficients of the dyes, and excitation energy of the dyes. Their electron cloud delocalization in HOMO/LUMO levels were studied by DFT using Gaussian 09 software. Time-dependent density functional theory (TD-DFT) was applied to theoretically explore the first excitation energy (E0-0) of these dyes, which was in good agreement with experimental results.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model and predict the effects of solvation within porous materials, I hope to 23814-12-2 help many people in the next few years.

Cationic mu-alkyl dicopper complexes [Cu-2(mu-eta(1):eta(1)-R)DPFN]NTf2 (R = CH3, CH2CH3, CH2C(CH3)(3); DPFN = 2,7-bis (fluoro-di (2-pyridyl) methyl)-1,8-naphthyridine NTf2- = N(SO2CF3)(2)) were synthesized by treatment of the acetonitrile-bridged dicopper complex [Cu-2(eta(1):eta(1)-NCCH3)DPFN](NTf2)(2) with LiR or MgR2. Structural characterization by X-ray crystallography and NMR spectroscopy revealed that the alkyl ligands symmetrically bridge the two copper centers, and the complexes persist in room-temperature solution. Notably, the mu-methyl complex showed less than 20% decomposition after 34 days in room-temperature THE solution. Treatment of the mu-methyl complex with acids allows installation of a range of monoanionic bridging ligands. However, surprisingly insertion into the dicopper-carbon bond was not observed upon addition of a variety of reagents, suggesting that these complexes exhibit a fundamentally new reactivity profile for alkylcopper species. Electrochemical characterization revealed oxidation-reduction events that evidence putative mixed-valence dicopper alkyl complexes. Computational studies suggest that the dicopper-carbon bonds are highly covalent, possibly explaining their remarkable stability.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 754-05-2, in my other articles. Product Details of 754-05-2.
