Efficient and Stable Solution-Processed Organic Light-Emitting Transistors Using a High-k Dielectric

We report the development of highly efficient and stable solution-processed organic light-emitting transistors (OLETs) that combine a polymer heterostructure with the transparent high-k dielectric poly(vinylidenefluoride(0.62)-trifluoroethylene(0.31)-chlorotrifluoroethylene(0.7)) (P(VDF-TrFE-CTFE)). The polymer heterostructure comprises of poly[4-(4,4-dihexadecyl-4H-cyclopenta[1,2-b:5,4-b’]-dithiophen-2-yl)-alt-[1,2,5]thiadiazolo[3,4-c]pyridine] (PCDTPT) and Super Yellow as charge-transporting and light-emitting layers, respectively. Device characterization shows that the use of P(VDF-TrFE-CTFE) leads to larger channel currents (approximate to 2 mA) and lower operating voltages (-35 V) than for previously reported polymer based OLETs. Furthermore, the combined transparency of the dielectric and gate electrode, results in efficient bottom emission with external quantum efficiency of approximate to 0.88% at a luminance L >= 2000 cd m(-2). Importantly, the resulting OLETs exhibit excellent shelf life and operational stability. The present work represents a significant step forward in the pursuit of all-solution-processed OLET technology for lighting and display applications.

Synthesis, Characterization, Antitumor Activity, and Theoretical Calculations of Co(II) Complex Based on Pyridine-2,6-dicarboxylic Acid

A new cobalt complex, namely[Co(Hpdc)(bpy)Cl]center dot C2H5OH (bpy=2,2′-bipyridine), was synthesized by using pyridine-2,6-dicarboxylic acid (H(2)pdc) as ligand under hydrothermal condition, and followed by experimental characterization of infrared spectroscopy and X-ray single-crystal diffraction. To deeply reveal the electronic structure of this complex, density functional theory calculations were employed to investigate its charge distribution, electrostatic potential, frontier molecular orbitals, and relevant electronic properties under aqueous condition. Moreover, the antitumor activity of this complex was evaluated by thiazolyl blue tkloYetrazolium bromide (MTT) assay in chronic myelocytic leukemia (K562) and esophageal carcinoma (OE-19) cancer cell lines, and the resulting IC50 values were estimated to be as low as (0.22 +/- 0.05) mu g.mL(-1) and (0.82 +/- 0.16) mu g.mL(-1) (i. e., (0.48 +/- 0.11) mu mol.L-1 and (1.77 +/- 0.35) mu mol.L-1) for K562 and OE-19, respectively, demonstrating its cytotoxic activity against these two cancer cell lines.

Experimental and DFT insights into nitrogen and sulfur co-doped carbon nanotubes for effective desulfurization of liquid phases: Equilibrium & kinetic study

Herein, nitrogen and sulfur co-doped carbon nanotubes (NS-CNT) adsorbents were synthesized via the chemical vapor deposition technique at 1000 degrees C by employing the camphor, urea and sulfur trioxide pyridine. In this study, desulfurization of two types of mercaptans (dibenzothiophene (DBT) and tertiary butyl mercaptan (TBM) as nonlinear and linear forms of mercaptan) was studied. In this regard, a maximum capacity of NS-CNT was obtained as 106.9 and 79.4 mg/g and also the removal efficiencies of 98.6% and 88.3% were achieved after 4 h at 298K and 0.9 g of NS-CNT for DBT and TBM, respectively. Characterization of the NS-CNTs was carried out through exploiting scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and elemental analysis (CHN). The isotherm equilibrium data could be ascribed to the Freundlich nonlinear regression form and the kinetic data was fitted by nonlinear form of the pseudo second order model. The negative values of Delta S-0, Delta H-0 and Delta G(0) specify that the adsorption of both types of mercaptans was a natural exothermic process with a reduced entropy. Maintenance of more than 96% of the adsorption capacity even after nine cycles suggest the NS-CNT as a superior adsorbent for mercaptans removal in the industry. Density functional theory (DFT) calculations were also performed to peruse the effects of S/N co-doping and carbon monovacancy defects in CNTs toward the adsorption of DBT and TBM.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 143468-13-7, in my other articles.

Study of acute oral toxicity of the thiazole derivative N-(1-methyl-2-methyl-pyridine)-N-(p-bromophenylthiazol-2-yl)-hydrazine in a Syrian hamster

The thiazole derivative N-1-methyl-2-methyl-pyridine)-N-(p-bromophenylthiazol-2-yl)-hydrazine was used to evaluate the acute oral toxicity in Syrian hamsters. The concentration of the doses (300 mg/kg and 2000 mg/kg) were based on the Class Acute Toxicity Method displayed in the OECD-423 guide. In addition, renal and liver biochemical tests were performed, as well as histopathological analysis. Our results showed that the compound’s lethal dose (LD50) was 1000 mg/kg and classified as category 4 according to the criteria adopted in the experiment’s protocol. Biochemical analysis of the liver function’s parameters showed that the LD50 values in all animals were higher than the reference values. However, the analyze of the kidney injury parameters showed an increase in the urea’s dosage but a decrease in the albumin’s dosage in all animals when compared to the reference values. Kidney biochemical analysis also showed that creatinine’s level was only higher than the reference values in one animal. Massive damages in the liver were observed, such as hypertrophy and hyperplasia of the hepatocyte, coagulation necrosis, the presence of mononuclear cells in the sinusoidal capillaries, steatosis, cholestasis, and congestion of sinusoidal capillaries and central-lobular veins. The animals presented renal injuries related to congestion of glomerular and interstitial capillaries, nephrosis of contorted proximal and distal tubules and congestion in the medullary region. In conclusion, the thiazole derivative was well tolerated although it caused acute liver and kidney damages. Therefore, these results showed the need of further investigation of this compound in vivo to evaluate the potential therapeutic effects with chronic models.
