The photocatalytic reduction of carbon dioxide (CO2) to value-added chemicals is an attractive strategy to utilize CO2 as a feedstock for storing renewable energy, such as solar energy, in chemical bonds. Inspired by the biological function of the nicotinamide adenine dinucleotide redox couple (NAD(+)/NADH), we have been developing transition-metal complexes containing NAD(+)/NADH-functionalized ligands to create electro-and/or photochemically renewable hydride donors for the conversion of CO2 into value-added chemicals. Our previous fi ndings have provided insights for the development of photocatalytic organic hydride reduction reactions for CO2, however, further examples, as well as investigation, of these photo-driven NAD(+)/NADH-type hydrogenation and organic hydride transfer reactions are required not only to explore the mechanism in detail but also to develop a highly ef fi cient catalyst for arti fi cial photosynthesis. In this paper, we report the synthesis, characterization, and photo-induced NAD(+)/NADH conversion properties of a new ruthenium(II) complex, [Ru(bpy)(2)(Me-pn)](PF6)(2) (1), which contains a new NAD(+)-type ligand, Me-pn (2-methyl-6-(pyridin-2-yl)-1,5-naphthyridine). In addition, we have succeeded in the isolation of the corresponding two-electron reduced ruthenium(II) complex containing the NADH-type ligand Me-pnHH (2-methyl-6-(pyridin-2-yl)-1,4-dihydro-1,5-naphthyridine), i.e., [Ru(bpy)(2)(Me-pnHH)](PF6)(2) (1HH), by the photo-induced hydrogenation reaction of 1. Thus, in this study, a new photo-driven NAD(+)/NADH-type hydrogenation reaction for possible CO2 reduction using the NAD(+)/NADH redox function has been constructed.

In an article, author is Ismayilov, Rayyat Huseyn, once mentioned the application of 5959-52-4, Name is 3-Amino-2-naphthoic acid. Now introduce a scientific discovery about this category, SDS of cas: 5959-52-4.

Through a pyrimidine and naphthyridine-containing triamine ligand, N-2-(pyrimidin-2-yl)-N-7-(2-(pyrimidin-2-ylamino)-1,8-naphthyridin-7-yl)-1,8-naphthyridine-2,7-diamine (H3N9-2pm), defective metal string complex [Ni-8.33(N-9-2pm)(4)(NCS)(2)](PF6)(2) (1) was successfully synthesized and structurally characterized. The complex consists of a linear metal chain and four deprotonated supporting ligands which are helically wrapped around the metal score. X-Ray crystallographic studies revealed that the complex (1) crystallizes in space group P2(1)/c of the monoclinic system. The small J value (J = -2.90 cm(-1)) suggests quite a weak magnetic interaction throughout the molecule of complex (1). The weak magnetic interaction in the defective complex indicates that the spin exchange in metal string occurs through the metal core rather than the bridging ligands. The electrochemical study on complex 1 shows abundant redox properties and facility to the reduction in its cyclic voltammogram by displaying three reversible redox couples at E-1/2 = – 0.35, – 0.69 and – 0.88 V.

In a document, author is Urbanaviciute, Indre, introduce the new discover.

We report a synthesis of 37 new 1,8-naphthyridine based compounds having a non-planar bicyclic moiety (bicyclo[3.3.1]nonane, bicyclo[3.3.0]octane and camphor). We measured energetic characteristics (E-Homo= [-5.9; -5.4] eV, E-LUMO = [-3.4; -2.4] eV and E-g_opt = [2.3; 3] eV), tested photoluminescence (PL) properties in chloroform solution (PL peaks at 390-490 nm range; QY reaching 53%) and produced multilayer OLED structures with our new materials as an emissive layer (EML). With changing the EML material, we observed electroluminescence (EL) covering a wide colour spectrum: red-orange, yellow, lettuce-green, green, blue-green (compared to violet from a control device). A broad white EL spectrum was registered for OLEDs with duplex non-planar V conformation molecules as an EML. The analysis of the results let us obtain precious information about the influence of molecular structure peculiarities on PL and EL spectra, as well as on values of the HOMO, the LUMO and E-g_opt, that are universal for all molecular systems.

Novel ruthenium (II) complexes were prepared containing 2-phenyl-1,8-naphthyridine derivatives. The coordination modes of these ligands were modified by addition of coordinating solvents such as water into the ethanolic reaction media. Under these conditions 1,8-naphthyridine (napy) moieties act as monodentade ligands forming unusual [Ru(CO)(2)Cl-2(eta(1)-2-phenyl-1,8-naphthyridine-kN)(eta(1)-2-phenyl-1,8-naphthyridine-kN ‘)] complexes. The reaction was reproducible when different 2-phenyl-1,8-naphthyridine derivatives were used. On the other hand, when dry ethanol was used as the solvent we obtained complexes with napy moieties acting as a chelating ligand. The structures proposed for these complexes were supported by NMR spectra, and the presence of two ligands in the [Ru(CO)(2)Cl-2(eta(1)-2-phenyl-1,8-naphthyridine-kN)(eta(1)-2-phenyl-1,8-naphthyridine-kN ‘)] type complexes was confirmed using elemental analysis. All complexes were tested as catalysts in the hydroformylation of styrene showing moderate activity in N,N ‘-dimethylformamide. Copyright (C) 2008 John Wiley & Sons, Ltd.

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 1631-25-0, in my other articles. COA of Formula: https://www.ambeed.com/products/1631-25-0.html.

A family of low-valent Ni-2, Co-2, and Fe-2 naphthyridine-diimine (NDI) complexes is presented. Ligand-based pi* orbitals are sufficiently low-lying to fall within the metal 3d manifold, resulting in electronic structures that are highly delocalized across the conjugated [NDI]M-2 system. This feature confers stability to metalmetal interactions during two-electron redox reactions, as demonstrated in a prototypical oxidative addition of allyl chloride.

In an article, author is Lu, Yihuan, once mentioned the application of 13922-41-3, Name is Naphthalen-1-ylboronic acid, molecular formula is C10H9BO2. Now introduce a scientific discovery about this category, Reference of 13922-41-3.

An expanded GGGGCC hexanucleotide (G(4)C(2)) repeat within the non-coding region of C9ORF72 gene has been identified as the most common genetic cause of FTD/ALS kindred, and synthetic ligand targeting this pathological expansion sequence holds a promising approach for the disease interference. We here describe the naphthyridine carbamate tetramer, p-NCTB, as a binding ligand to hairpin G(4)C(2) repeat. p-NCTB simultaneously recognizes two distal CGGG/CGGG sites in G4C2 repeat DNA and RNA leading to the formation of the interhelical (inter-and intrastrand) binding complexes. The intrastrand binding was predominant when p-NCTB bound to long repeat sequence that accommodates multiple binding sites by folding into hairpins, while the interstrand binding was exclusive for short repeat sequence. The binding of p-NCTB showed repeat-length selectivity: the longer repeat sequence is a better target for p-NCTB. p-NCTB demonstrated inhibition of transcription against G(4)C(2) repeat template in vitro in a repeat length-dependent manner.
