The asymmetric unit of the title compound, [Ru(C13H9N3)(C15H11N3)(H2O)](PF6)(2)center dot 1.5C(3)H(6)O, consists of two crystallographically independent RuII complexes. Each complex is approximately octahedral with the RuII atom bound by an N,N’-coordinated 2-(2-pyridyl)-1,8-naphthyridine (pynp) ligand, a meridional 2,2′:6′,2”-terpyridine (tpy) ligand and one aqua ligand. The tpy ligand is coordinated in a planar tridentate fashion with the central N atom closest to the RuII atom. The aqua ligand is trans to the pyridine N atom of pynp. The long Ru-O distances [2.150 (5) and 2.138 (5) A] are typical for aqua ligands in polypyridyl ruthenium complexes. In the crystal, both intramolecular O-H…N and intermolecular O-H…O hydrogen bonds are observed.

In a document, author is Whittemore, Tyler J., introduce the new discover.

A series of dirhodium(II,II) paddlewheeel complexes of the type cis-[Rh-2(mu-DTolF)(2)(mu-L)(2)] [BF4](2), where DTolF = N,N’-di(p-tolyl)formamidinate and L = 1,8-naphthyridine (np), 2-(pyridin-2-yl)-1,8-naphthyridine (pynp), 2-(quinolin-2-yl)-1,8-naphthyridine (qnnp), and 2-(1,8-naphthyridin-2-yl)quinoxaline (qxnp), were synthesized and characterized. These molecules feature new tridentate ligands that concomitantly bridge the dirhodium core and cap the axial positions. The complexes absorb light strongly throughout the ultraviolet/visible range and into the near -infrared region and exhibit relatively long-lived triplet excited-state lifetimes. Both the singlet and triplet excited states exhibit metal/ligand-to-ligand charge transfer (ML-LCT) in nature as determined by transient absorption spectroscopy and spectroelectrochemistry measurements. When irradiated with low -energy light, these black dyes are capable of undergoing reversible bimolecular electron transfer both to the electron acceptor methyl viologen and from the electron donor p-phenylenediamine. Photoinduced charge transfer in the latter was inaccessible with previous Rh-2(II,II) complexes. These results underscore the fact that the excited state of this dass of molecules can be readily tuned for electron-transfer reactions upon simple synthetic modification and highlight their potential as excellent candidates for p- and n-type semiconductor applications and for improved harvesting of low -energy light to drive useful photochemical reactions.

A theoretical study of the dimer formation of chiral 1,8a-dihydro-1,8-naphthyridine derivatives has been carried out by means of DFT calculations. In the cases treated, the heterochiral dimers (RS or SR) are always more stable than the homochiral ones (RR or SS). Two possible proton transfer processes have been studied, the concerted and the non-concerted ones. The non-concerted TS corresponds to a true TS while the concerted one presents two imaginary frequencies. The geometrical characteristics of the hydrogen bonds in all the structures calculated have been correlated using the Steiner-Limbach model.

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 39156-41-7, in my other articles. Recommanded Product: 39156-41-7.

In a article, author is Kim, Jin Hong, introduce new discover of the category.

We describe herein the comprehensive theoretical and experimental studies on the transistor mobility of organic semiconductors by correlating a two-dimensional (2D) intermolecular interaction with thin-film morphology and the electronic coupling structure. We developed a novel bis-lactam-based small molecule, 1,5-dioctyl-3,7-di(thiophen-2-yl)-1,5-naphthyridine-2,6-dione (C8-NTDT), with a 2D-type C-H center dot center dot center dot O=C intermolecular interaction along the in-plane directions of the crystal packing structure, which is characteristically different from the one-dimensional-type intermolecular interaction shown in the typical bis-lactam molecule of 2,5-dioctyl-3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4-dione (C8-DPPT). Experimentally and theoretically, C8-NTDT exhibited more favorable thin-film morphology and an electronic coupling structure for charge transport because of its unique 2D intermolecular interactions compared with C8-DPPT. In fact, C8-NTDT exhibited a hole mobility of up to 1.29 cm(2) V-1 s(-1) and an on/off ratio of 10(7) in a vacuum-processed device. Moreover, the high solubility with the 2D electronic coupling structure of C8-NTDT enables versatile solution processing for device fabrication without performance degradation compared to the vacuum-processed device. As an example, we could demonstrate a hole mobility of up to 1.10 cm(2) V-1 s(-1) for the spin-coated devices, which is one of the best performances among the solution-processed organic field-effect transistors based on bis-lactam-containing small molecules.

In a article, author is Zhang, Yu, introduce new discover of the category.

The 1,8-naphthyridine and diiodine were selected as model molecules to investigate the possible effect of the strong N center dot center dot center dot I halogen bond on the electronic structures and properties of potential organic semiconductor building blocks. The N center dot center dot center dot I halogen bond in the crystal structure of the cocrystal formed between 1,8-naphthyridine and diiodine has an interaction energy of -21.41 kcal/mol. The cooperativity and anticooperativity between the strong halogen bond and other noncovalent interactions, including the hydrogen bond, tetrel bond and stacking interaction, were also studied in detail. The formation of the strong N center dot center dot center dot I halogen bond leads to the formation of the regularly layered structures of the cocrystal, which is a necessary condition for the organic semiconductor to conduct electrons or holes. On the other hand, the formation of the strong N center dot center dot center dot I halogen bond lowers both the energy of the lowest unoccupied molecular orbital of 1,8-naphthyridine and the energy gap of frontier molecular orbitals of 1,8-naphthyridine. These results clearly show that the strong halogen bond can be used as a cheap and effective tool for the design and synthesis of organic semiconductor materials.

Routine detection of trace amounts of Pb2+ is of significant importance because it poses severe risks to human health and the environment. In this paper, a novel label-free fluorescence platform for the sensitive detection of Pb2+ has been successfully constructed by using Pb2+-specific 8-17 DNAzyme as the molecular recognition element, 2-amino-5,6,7-trimethyl-1,8-naphthyridine (ATMND) as the signal reporter, and exonuclease III (Exo III) as the signal amplifier. A good linearity between the fluorescence intensity and the logarithm of Pb2+ concentration was obtained in the range from 100 pM to 10 M with a correlation coefficient (R-2) of 0.99. The sensing system exhibited ultrasensitivity towards Pb2+ at low concentration (50 pM) without any labeling, modification, immobilization, or washing procedure. Besides, the proposed method was also highly selective for Pb2+ against other metal ions. This biosensor was robust and can be applied for the determination of Pb2+ in complex samples with desired recovery and good accuracy. With the successful demonstration of Pb2+ detection, the label-free biosensor can be readily expanded to monitor other targets in a simple, cost-effective, and ultrasensitive way by replacing the target-specific molecular recognition elements.

Synthesis and investigation of antimicrobial activity of 6 novel 1,8-naphthyridine-3-carboxylic acid derivatives are presented. Among the derivatives, compounds 4a-5b2 showed a broad-spectrum antimicrobial activity against all reference Gram-positive, Gram-negative bacteria and fungi. These compounds exhibited remarkable bactericidal activity against Staphylococcus and Bacillus sps. The tested substances 4a-5b2 were found also found to be active against Escherichia coli, Salmonella and Shigella sps. The chlorine substituted compounds 4a and 5a2 were found to be the most active towards the tested microorganisms. Compounds 4a-5b2 were found to be fungicidal against Candida sp. with a MIC values in the range of 400-2000 mu g/ml. Docking studies of these compounds with Salmonella typhi OmpF complexed with ciprofloxacin using PDB-4KRA revealed that the compounds acted as covalent crosslinker on the DNA gyrase B of the former and intercalate the latter both with higher C score values. Thus, the antibacterial activity against tested strains suggested 1,8-naphthyridine-3-carboxylic acid derivatives warrant further evaluation as potential novel antiinfective agents. The antifungal activity of these compounds was comparable to that of griseofulvin. The drug-likeness data of synthesized compounds made them promising leads for the future development as antifungal agents.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind. Thanks for taking the time to read the blog about 496-72-0, Safety of 3,4-Diaminotoluene.
