In a document, author is Urbanaviciute, Indre, introduce the new discover, Recommanded Product: 91-76-9.

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.

Thienylzinc halides and related compounds prepared by deprotonation followed by transmetalation were used in copper-catalyzed amination using N-benzoyloxy secondary amines. By extending the reaction to 1,5-naphthyridine, it was showed that the competitive dimer formation observed in the case of thiophenes was linked with the low stability of some thienylamines rather than homocoupling. Interestingly, thienylzinc halides and related compounds prepared by transmetalation of thienylmagnesium halides, either prepared from their bromo-precursors or generated by deprotometalation, were satisfactorily employed in cobalt-catalyzed aminations. Finally, aminothiophenes were involved in copper-catalyzed mono- and di-N-arylations, affording differently substituted di- and triphenylamines.

In the present work three chromeno naphthyridine derivatives (CNs) have been synthesized using one pot multicomponent reaction of 2, 4-hydroxyacetophenone, aromatic aldehydes and malononitrile in water using silica gel as a catalyst. The simulated LDse values for the synthesized compounds are 340 mg/kg (CN-1), 1500 mg/kg (CN-2) and 800 mg/kg (CN-3) which suggest their non-toxic and eco-friendly nature The performance all the three compounds as corrosion inhibitors in 15% HCl on N80 has been analyzed via weight loss, electrochemical, surface characterization, and density functional theory (DFT) methods. Chromeno naphthyridine (CN-1) shows maximum inhibition efficiency of 98.3% at only 300 mg/L The measurement of EIS reveals the process of inhibition of corrosion is governed by control of charge transfer. The mixed nature of CNs adsorption is suggested by results of PDP. Langmuir model of adsorption shows the perfect fitting. Adsorption of CNs onto the metal surface was supported by MR. AFM, and UV-vis. Computational modelling using DFT data reveals that corrosion inhibition takes place by adsorption of both neutral and protonated forms on steel surface. Molecular dynamic simulation (MDS) suggests the parallel adsorption of CNs molecules both in neutral and protonated forms. (C) 2020 Elsevier B.V. All rights reserved.
