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.

While the job of a research scientist varies, Electric Literature of 496-72-0, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards.496-72-0, Name is 3,4-Diaminotoluene, SMILES is CC1=CC=C(N)C(N)=C1, belongs to naphthyridine compound. 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.

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.

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.

In a article, author is Oyama, Dai, introduce new discover of the category.

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 Hou, Xueyan, introduce the new discover.

A series of novel 3-(1,3,4-oxadiazol-2-yl)-1,8-naphthyridin-4(1H)-one derivatives were synthesized and their anti-cancer as well as cisplatin sensitization activities were evaluated. Among them, compounds 6e and 6h exhibited significant cisplatin sensitization activity against HCT116. Hoechst staining and annexin V-FITC/PI dual-labeling studies demonstrated that the combination of 6e/6h and cisplatin can induce tumour cell apoptosis. Western blot showed that the expression of ATR downstream protein, CHK1, decreased in 6e + cisplatin and 6h + cisplatin groups compared with that in the test compound and cisplatin group. Furthermore, docking of 6e/6h into the ATR structure active site revealed that the N1 and N8 atoms in the naphthyridine ring and the hybrid atom in the oxadiazole ring are involved in hydrogen bonding with Val170, Glu168 and Tyr155. Additionally, the naphthyridine ring is also involved in – stacking with Trp169. Accordingly, compounds 6e and 6h can be expected to be potential cisplatin sensitizers that can participate in HCT116 cancer therapy.

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 98796-51-1, in my other articles.
