A series of new luminescent non-planar 1,8-naphthyridine derivatives giving coloured and close-to-white electroluminescence spectra

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.

Synthesis and Spectroscopic Distinction of Benzonaphthonaphthyridine and Its Isomer

Distinction of benzo[h]naphtho[1,2-b][1,6]naphthyridine and its isomeric benzo[b]naphtho[1,2-h][1,6]naphthyridine is well explained on the basis of various spectroscopic techniques. Initially these isomers were prepared from their respective chloroquinolines via anilinoquinolines as potential intermediates. Spectroscopic dissimilarities of their precursors and intermediates have also been considered and compared with the final benzonaphthonaphthyridine isomers.

Reusable Fe3O4/ZnO/MWCNTs Magnetic Nanocomposites Promoted Synthesis of New Naphthyridines

The Fe3O4/ZnO/MWCNTs magnetic nanocomposites as a high performance organomettalic catalyst was employed for the preparation of naphthyridine derivatives in high yields via five component reaction of isoquinoline, dialkyl acetylenedicarboxylates or propiolates, alpha-haloketones, triphenyphophine and ammonium acetate in aqueous media at ambient temperature. The Fe3O4/ZnO/MWCNTs MNCs were synthesized using ionic liquid [OMIM]Br as a stabilizer and soft template. As well Fe3O4/ZnO/MWCNTs MNCs show a good improvement in the yield of the product and showed significant reusable ability. Due to having isoquinoline core, we investigate antioxidant property of some synthesized compounds by diphenyl-picrylhydrazine (DPPH) radical trapping and power of ferric reduction experiment. Furthermore, the disk diffusion test on Gram positive and negative bacteria are utilized for investigation of antimicrobial activity of some naphthyridines. The achieved outcomes of this experiment demonstrate that these synthesized compounds could prevent from growth of bacteria. Short time of reaction, high yields of product, easy separation of catalyst and products are some benefits of this process.

Effect of Specific Solute-Solvent Interaction and Electron Donor-Acceptor Substituents of Novel Pyrazolo Naphthyridines on Fluorescence

Heterocyclic orthoaminoaldehyde such as 4-amino-3-(4-phenyl)-1-phenyl-1H-Pyrazolo[3,4-b]pyridine-5-carbaldehyde was synthesized by multistep reactions involving reduction of azido derivative 2 with LAH to yield aminoalcohol 3 and oxidation of it with MnO2 to aminoaldehyde 4.The pyridine ring annulated on to 4 by Friedlander condensation using acetophenones in presence of base to obtained pyrazolo[3,4-h][1,6]naphthyridine 5 in excellent yield. Study of photophysical properties of 5 revealed that the absorption and emission of them depends up on the substituents present on benzene ring in newly annulated pyridine ring.

Optimizing Polymer Solar Cells Using Non-Halogenated Solvent Blends

More environmentally friendly polymer solar cells were constructed using a conjugated polymer, poly (2,5-thiophene-alt-4,9-bis(2-hexyldecyl)-4,9-dihydrodithieno[3,2-c:3 ‘,2 ‘ h][1,5] naphthyridine-5,10-dione, PTNT, as a donor material in combination with PC71BM as an acceptor in a bulk heterojunction device structure. A non-halogenated processing solvent (o-xylene) and solvent additives that are less harmful to the environment such as 1-methoxynaphthalene (MN) and 1-phenylnaphthalene (PN) were used throughout the study as processing solvents. The most widely used halogenated solvent additives (1,8-diiodooctane (DIO) and 1-chloronaphthalene (CN)) were also used for comparison and to understand the effect of the type of solvent additives on the photovoltaic performances. Atomic force microscopy (AFM) was employed to investigate the surface morphology of the films prepared in the presence of the various additives. The best-performing polymer solar cells provided a high open-circuit voltage of 0.9 V, an efficient fill factor of around 70%, and a highest power conversion efficiency (PCE) of over 6% with the use of the eco-friendlier o-xylene/MN solvent systems. Interestingly, the solvent blend which is less harmful and with low environmental impact gave a 20% rise in PCE as compared to an earlier reported device efficiency that was processed from the chlorinated solvent o-dichlorobenzene (o-DCB).
