Low cost and high performance white polymer light-emitting diodes (PLEDs) are very important as solid-state lighting sources. In this research three commercially available phosphors were carefully chosen, bis[2-(4,6-difluorophenyl) pyridinato-N, C-2](picolinate) iridium(III) (FIrpic), bis[2-(2-pyridinyl-N) phenyl-C](2,4-pentanedionato-O-2, O-4) iridium(III) [Ir(ppy)(2)(acac)], and bis(2-phenyl-benzothiazole-C-2, N)(acetylacetonate) iridium(III) [Ir(bt)(2)(acac)], plus a home-made red phosphor of tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium(III) [Ir(MPCPPZ)(3)], and their photophysical and morphological properties were systematically studied as well as their applications in single-emission layer white PLEDs comprising poly(N-vinylcarbazole) as host. Additionally, the electrochemical properties and energy level alignment, possible energy transfer process, and thin-film morphology were also addressed. The binary blue/ orange complementary white PLEDs exhibit stable electroluminescence spectra, wide spectrum-covering region range from 380-780 nm, and high color rendering index (CRI) over 70 with Commission Internationale de l’Eclairage coordinates x, y (CIEx,y) of (0.388, 0.440), correlated color temperature (CCT) of around 4400, plus high efficiency of 25.5 cd A(-1). The optimized red-green-blue white PLEDs showed a satisfactory CRI of around 82.4, maximum current efficiency of 20.0 cd A(-1) and external quantum efficiency (EQE) of 10.8%, corresponding to a CCT of 3700-2800, which is a warm-white hue. At last, stable and high color quality, red-green-orange-blue four component white PLEDs, with a CRI of over 82, a high efficiency of 24.0 cd A(-1), EQE of 11.5%, and high brightness of 43 569.9 cd m(-2) have been obtained.

Synthetic Route of 62-23-7, 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 62-23-7 is helpful to your research.

In the complex the hydrazone ligand chelates to the nickel(II) through nitrogen atoms in a bidentate manner. The antifungal activity of the ligand and its nickel(II) complex 3 was studied against Aspergillus niger, Aspergillus flavus and Candida albicans. The results revealed modest activity of the complex (3) against the tested organisms with inhibition zones of 14, 14 and 13 mm, compared to the free ligand 1 with inhibition zones of 11 mm each for A. niger, A. flavus and C. albicans respectively.

Much attention has been paid to heterocyclic N-containing ligands due to their applicability as bridging ligands in the synthesis of redox active dinuclear metal complexes. With this aim, we report the synthesis and full characterization of a novel phthalazine-triazole ligand (1,4-bis(1-methyl-1H-1,2,3-triazol-4-yl) phthalazine). Moreover, we show that the phthalazine nitrogen atoms of this N-heterocyclic ligand are more reactive towards alkylating agents than the triazole groups. New ruthenium(II) complexes containing this ligand have been obtained and characterized both structurally and electrochemically. The geometry imposed by the ligand allows the placement of two ruthenium centers in very close proximity so that efficient through-space interactions take place, a concept of crucial importance for electron transfer processes.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 139-66-2, Name is Diphenylsulfane, molecular formula is C12H10S, belongs to phthalazine compound, is a common compound. In a patnet, author is Soliman, Saied M., once mentioned the new application about 139-66-2, SDS of cas: 139-66-2.

A new Schiff base derived from the antihypertensive hydralazine (LH) and its Co(III) complexes [CoL2] X*4H(2)O, where X = NO3 (1) or Cl (2), were synthesized and characterized using FTIR, UV-Vis,H-1 NMR spectroscopy as well as thermal analysis. The crystal structures of the three compounds have been determined using single crystal X-ray diffraction technique. The two complexes structure is strictly divided in a highly ordered part of the [CoL2](+) units and a disordered section containing the anions and sixteen crystal water molecules per unit cell. In the complexes, the two ligand anions (L-) chelate to the Co(III) through the nitrogen atoms in a tridentate meridional manner. The pyridine and phthalazine rings showed deviations from co-planarity in all compounds which attributed to the crystal packing effects as revealed by analysis of their molecular packing using Hirshfeld analysis and further supported by DFT calculations. The optimized structure of the [CoL2] NO3 as a model showed no co-planarity of the two rings while perfectly planar ligand units were predicted in the [CoL2](+) cation indicating that the intermolecular interactions with the nitrate counter anion have a major role in the deviations of the two ring moieties from planarity. The ligand anion (L-) optimized structure using B97D function which include dispersion model showed similar results while the functions (B3LYP and mPW1PW91) which include no dispersion model predicted perfectly planar arrangement. Atoms in molecules (AIM) studies predicted the strength of the Co-N interactions is in the order, Co-N(azomethine) > Co-N(phthalazine) > Co-N(pyridine) which are generally stronger in 2 than 1. The developmental toxicity of LH and its complexes were tested in zebrafish embryos. The ligand itself was very toxic with LC50 of just 2 mu M as compared to its metal complexes, whereas, at sub-lethal concentration the ligand perturbed the neurogenesis in zebrafish embryos.
