Cost-effective fabrication of white organic light-emitting diodes (WOLED) is meaningful toward commercial application of environment-friendly solid-state lighting sources. Electroluminescent efficiency and color quality are two opposite performance characteristics facing solution processed WOLEDs requiring balanced consideration. Herein, a recently synthesized molecule of 4,4′-(9,9′-(1,3-phenylene) bis(9H-fluorene-9,9-diyl)) bis(N,N-diphenylaniline) (DTPAFB) is introduced as a host material for solution processed all-phosphor WOLEDs, embracing four well-known molecules which are blue iridium (III) bis(2-(4,6-difluorophenyl) pyridinato-N,C-2)(picolinate) (FIrpic), green iridium (III) bis[2-(2-pyridinyl-N) phenyl-C](2,4-pentanedionato-O-2,O-4)[Ir(ppy)(2)(acac)], and orange iridium (III) bis(2-phenyl-benzothiazole-C-2, N)(acetylacetonate) [Ir(bt)(2)(acac)] plus a home-made red phosphor of iridium (III) tris(1-(2,6dimethylphenoxy)-4-(4-chlorophenyl) phthalazine) [Ir(MPCPPZ)(3)]. Illumination quality white light with high brightness, high efficiency, suitable correlated color temperature (CCT), high color-rendering index (CRI), and stable electroluminescent (EL) emission is obtained. A stable white emission with a CRI over 70, Commission Internationale de L’Eclairage (CIE) of (0.37, 0.42), and high EL efficiency of 19.6 lm W-1 at high luminance of 2000 cd m(-2) for blue/orange complementary color WOLEDs is demonstrated. The optimized red/green/blue three primary color WOLEDs show improved CRI up to 81, moderate high efficiency of 25.8 cd A(-1), 14.4 lm W-1, and EQE of 13.9%. Furthermore, the red/green/blue/orange four primary color WOLEDs show the optional balance between color quality and EL efficiency with high CRI of around 81-83 and medium CCT of 3755-3929 K which is warm and soft to human eyes. At an illumination relevant luminance of 1000 cd m(-2), the total power efficiency reaches 33.6 lmW(-1), and still remains 30.2 lm W-1 at 3000 cd m(-2), approaching the efficiency of state-of-the-art fluorescent-tube (40 – 70 lm W-1), potentially suitable as an environment-friendly solid-state lighting source. This work indicates that developing high performance host materials and highly efficient phosphors and carefully combining them with common phosphors is an effective way toward high performance WOLEDs.

The volatile, harmful and hazardous solvents have impact on human health, all organisms and environment. To reduce the use of hazardous volatile solvents, there is need to develop the alternative green reaction medium for organic transformations and is the main goal of green chemistry. The green solvent should be nonvolatile, nontoxic, biodegradable and biorenewable. Considering these parameters, herein, we have reported an efficient and environmentally benign green synthesis of chromeno pyrazolo and indazolo phthalazine derivatives in deep eutectic solvent. The present protocol contains excellent yield of the product, short reaction time, operation simplicity, reusability of solvent and no need of further purification.

In the present work, amorphous silica nanoparticles were synthesized from low-cost rice husk ash (RH-SiO2). The nanoparticles were later modified by an acidic ionic liquid containing double-charged diazoniabi-cyclo[2.2.2]octane chloride using sol-gel method (RH@[SiPrDABCO@BuSO3H]HSO4). The structural properties of this Bronsted solid acid were systematically investigated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermal gravimetric analysis-derivative thermogravimetric analysis (TGA-DTG), and Brunauer-Emmett-Teller (BET) measurements. The catalytic activity of this nanocomposite was successfully tested through the one-pot synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones via three-component couplings of phthalhydrazide, aromatic aldehydes, and malononitrile. The heterogeneous catalyst could be recovered easily and reused without significant loss of its catalytic activity.

In a document, author is Sen, Supriti, introduce the new discover.

A systematic study of the reaction of 1,4-dihydrazinophthalazine (DHPH) with 1,3-dicarbonyls [viz., acetylacetone (acac), dibenzoylmethane (bzbz), and 1-benzoylacetone (bzac)] varying the reaction conditions was carried out to obtain the phthalazine derivatives (1-4). One-pot reaction of DHPH with acac led to the formation of two compounds 1 and 2, with various factors such as the presence of the acid or base, amount of the acac, time of reflux, and the temperature. The reaction conditions of DHPH with bzbz or bzac are sort of different to isolate the products 3 and 4, respectively. The derivatives (1-4) have been characterized by elemental analyses, H-1 NMR, and electrospray ionization-mass spectrometry (ESIMS) and the cytotoxic activity of the compounds 1-4 was evaluated on HeLa cell line.

10-(1-Phthalazinylazo)-9-phenanthrol (HL, I) was synthesized by the reaction between 1-hydrazinophthalazine and 9,10-phenanthrenequinone. The crystal and molecular structures of compound I were determined by X-ray diffraction (XRD). According to XRD, EAS, and H-1 and C-13 NMR data, a HL molecule in solutions and in crystals exists in the form of quinohydrazone tautomer (b) (s-trans, cis) stabilized by intramolecular N(3)H…O(1) hydrogen bond. The mobile H atom is localized at the N(3) atom of the azo group. The phthalazine (A) and phenanthrenequinone (B) moieties of the HL molecule are nearly coplanar. The HL basicity and acidity constants (pK(a) = 1.90 and pK(a) = 11.65, respectively) and the formation constants of HL complexes with Zn2+ and Cd2+ and their compositions in solutions were determined. ML2 center dot DMFA complexes, where M = Zn2+, Cd2+, were synthesized. The coordination mode of the L- ligand with metal atoms was suggested.
