The title compound, C24H18N2, is the first structural example containing the 3,4-dihydrobenzo[b][1,6] naphthyridine fragment. It was synthesized from 2,4,6,8-tetraphenyl-3,7-diaza-bicyclo[3.3.1] nonan-9-one and was crystallized from a methanol-ethanol solution over two years as a racemate. The C=N double bond [1.2868 (15) angstrom] is bent significantly out of the plane of the aromatic bicyclic ring system [N-C-C-C = -157.63 (12)degrees] and out of the plane of the phenyl ring bonded at the 1-position [N-C-C-C = 41.15 (16)degrees].

Boron dipyrromethene type molecules (BODIPYs) are versatile molecules which have been used for applications ranging from photodynamic therapy to solar cells (DSSC). However, these molecules usually do not present high two-photon absorption cross-sections, limiting their use in nonlinear optical applications. Herein, we study a series of BF2-naphthyridine based boron-complexes with electron-donating and withdrawing groups to increase their two-photon absorption. We have found two-photon absorption cross-sections up to approximately 270 GM, which corresponds to an increase of approximately five times in comparison to the average cross-section value reported for molecules with similar conjugation length, indicating such compounds as potential materials for nonlinear applications in both the visible and infrared spectral regions.

Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. In an article, author is Huang, Xing-Cai, once mentioned the application of 1631-25-0, Name is N-Cyclohexylmaleimide, molecular formula is C10H13NO2. Now introduce a scientific discovery about this category, Application of 1631-25-0.

For a long time, the cobalt(II) complex ([Co(napy)(4)](ClO4)(2)) (napy=1, 8-naphthyridine) has been considered as an eight-coordinate complex without any structural proof. After careful considerations, two complexes [Co(napy)(2)Cl-2] (1) and [Co(napy)(4)](ClO4)(2) (2) based on the bidentate ligand napy were synthesized and structurally characterized. X-ray single-crystal structural determination showed that the cobalt(II) center in [Co(napy)(2)Cl-2] (1) is four-coordinate with a tetrahedral geometry (T-d), while [Co(napy)(4)](ClO4)(2) (2) is seven-coordinate rather than eight-coordinate with a capped trigonal prism geometry (C-2v). Direct-current (dc) magnetic data revealed that complexes 1 and 2 possess positive zero-field splitting (ZFS) parameters of 11.08 and 25.30 cm(-1), respectively, with easy-plane magnetic anisotropy. Alternating current(ac) susceptibility measurements revealed that both complexes showed slow magnetic relaxation behaviour. Theoretical calculations demonstrated that the presence of easy-plane magnetic anisotropy (D>0) for complexes 1 and 2 is in agreement with the experimental data. Furthermore, these results pave the way to obtain four-coordinate and seven-coordinate cobalt(II) single-ion magnets (SIMs) by using a bidentate ligand.

Application of 1631-25-0, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 1631-25-0 is helpful to your research.

Now introduce a scientific discovery about this category, Safety of 2,2-Dimethylpropane-1,3-diol.

The complexes of 2,7-bis(diphenylphosphorylamino)-1,8-naphthyridine (L) with lanthanide nitrates Ln(NO3)(3) (Ln = Nd, Lu) were investigated to elucidate the coordination ability of a novel type of potentially tetradentate ligands – bis(phosphorylamino) substituted naphthyridines. Mononuclear complexes of 1:1 and 1:2 composition, namely, [Nd(L)(NO3)(3)] (1a), [Nd(L)(NO3)(3)]center dot H2O (1b), [Lu(L)(NO3)(2)(H2O)](NO3) (2), [Nd(L)(2)(NO3)(2)(H2O)](NO3) (3), [Lu(L)(2)(NO3)(H2O)](NO3)(2)center dot 0.75CH(3)CN center dot H2O (4a) and [Lu(L)(2)(NO3) (H2O)](NO3)(2) (4b) were synthesized and studied by IR, Raman, and P-31 NMR spectroscopy in solid state and in solution. Structures of the complexes 1b and 4a were determined by X-ray diffraction. According to X-ray crystallography, vibrational spectroscopy and C, H, N, P elemental analysis data in solid 1:1 complexes one neutral molecule of L serves most likely as O,O,N,N-tetradentate ligand while in the 1:2 complexes only one ligand molecule coordinates in the same O,O,N,N-tetradentate fashion, and the second one serves as O-monodentate one. In solution the coordination mode of the ligand is preserved in all complexes. (C) 2011 Elsevier B. V. All rights reserved.

A novel fluorescent chemodosimeter based on 1,8-naphthyridine exhibits high selectivity to Zn2+ and Cu2+. When 1-(7-acetamino-1,8-naphthyridyl)2-(6-diacetaminopyridyl)ethene was mixed with CuCl2, hydrolysis of the acetamino group catalyzed by Cu2+ complex was first observed. Resulting from coordination and hydrolysis catalyzed by the corresponding complex of Zn2+ or Cu2+, the highly effective fluorescent detection of Zn2+ and Cu2+ is realized with Zn2+-selective dual-emission and Cu2+-selective ON-OFF behavior.

Scaffold hopping and structure-based drug design were employed to identify substituted 4-aminoquinolines and 4-aminonaphthyridines as potent, small molecule inhibitors of tumor necrosis factor alpha (TNF alpha). Structure-activity relationships in both the quinoline and naphthyridine series leading to the identification of compound 42 with excellent potency and pharmacokinetic profile are discussed. X-ray co-crystal structure analysis and ultracentrifugation experiments clearly demonstrate that these inhibitors distort the TNF alpha trimer upon binding, leading to aberrant signaling when the trimer binds to TNF receptor 1 (TNFR1). Pharmacokinetic-pharmacodynamic activity of compound 42 in a TNF-induced IL-6 mouse model and in vivo activity in a collagen antibody-induced arthritis model, where it showed biologic-like in vivo efficacy, will be discussed.
