Organic light-emitting diodes with an electro-deposited copper(I) thiocyanate (CuSCN) hole-injection layer based on aqueous electrolyte

Copper(I) thiocyanate (CuSCN) has been drawing much attention in optoelectronics due to its exceptional optical and electrical properties, as well as its processing versatility. The first organic light-emitting diodes (OLEDs) integrated with electro-deposited CuSCN crystalline thin films based on aqueous electrolyte were fabricated. With precisely tuned deposition parameters, the CuSCN thin films with satisfactory surface roughness and sufficient grain density were realized. We found that the driving voltage (voltage at a current density of 100 mA/cm2) and turn-on voltage of OLEDs using CuSCN as the hole injection layer (HIL) can be reduced by 1.41 and 1.79 V, respectively, compared with devices using vacuum-deposited hole injecting transition metal oxide molybdenum trioxide (MoO3). Moreover, the fabricated OLEDs also demonstrated considerably mitigated efficiency roll-off. Optical and energetic analyses were conducted to investigate the characteristics and enhancement mechanisms. Efficient hole-injection, electron blocking, improved charge balance, enhanced optical properties and good compatibility of electro-deposited CuSCN with thermally evaporated organic systems were found to be the primary contributors for the performance improvements of the OLEDs.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1111-67-7, and how the biochemistry of the body works.Application of 1111-67-7

Cu(I)-catalyzed, alpha-selective, allylic alkylation reactions between phosphorothioate esters and organomagnesium reagents

Regiocontrol of allylic alkylation reactions involving hard nucleophiles remains a significant challenge and continues to be an active area of research. The lack of general methods in which alpha-alkylation is favored underscores the need for the development of new processes for achieving this type of selectivity. We report that Cu(I) catalyzes the allylic substitution of phosphorothioate esters with excellent alpha-regioselectivity, regardless of the nature of the Grignard reagent that is used. To the best of our knowledge, the Cu-catalyzed allylic alkylation of phosphorothioate esters has never been described. We have also developed a simple protocol for inducing high alpha selectivity starting from secondary allylic halides. This is accomplished by using sodium phosphorothioates as an additive.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Quality Control of Cuprous thiocyanate, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1111-67-7, in my other articles.

Measurement of Antioxidant Capacity by Electron Spin Resonance Spectroscopy Based on Copper(II) Reduction

A new method is proposed for measuring the antioxidant capacity by electron spin resonance spectroscopy based on the loss of electron spin resonance signal after Cu2+ is reduced to Cu+ with antioxidant. Cu+ was removed by precipitation in the presence of SCN-. The remaining Cu2+ was coordinated with diethyldithiocarbamate, extracted into n-butanol and determined by electron spin resonance spectrometry. Eight standards widely used in antioxidant capacity determination, including Trolox, ascorbic acid, ferulic acid, rutin, caffeic acid, quercetin, chlorogenic acid, and gallic acid were investigated. The standard curves for determining the eight standards were plotted, and results showed that the linear regression correlation coefficients were all high enough (r > 0.99). Trolox equivalent antioxidant capacity values for the antioxidant standards were calculated, and a good correlation (r > 0.94) between the values obtained by the present method and cupric reducing antioxidant capacity method was observed. The present method was applied to the analysis of real fruit samples and the evaluation of the antioxidant capacity of these fruits. (Graph Presented).

High-efficiency perovskite solar cell using cobalt doped nickel oxide hole transport layer fabricated by NIR process

Lead halide perovskite solar cells (PVSCs) have potential toward commercialization because of their high efficiency and low cost. The hole transport layer (HTL) of p-i-n perovskite solar cell is usually made of NiOX. However, the NiOX needs to be processed at 300 C for 15 min for good hole transport property. This long heating time prohibits the development of continuous commercial process. Thus, a rapid heating process for the NiOX film deposition is critical to realize the commercialization of PVSCs in the future. In this study, we develop a facile method to obtain high quality NiOX films annealed by NIR in a short time of 50 s. A short-wave NIR lamp at 2500 K was used to systematically investigate the effect of NIR intensity on the film quality of sol-gel NiOX. The PVSCs fabricated from NIR-annealed NiOX (NIR-NiOX) film show a comparable power conversion efficiency (PCE) to those fabricated from traditional hot-plate annealed-NiOX (HP-NiOX). In addition, the NIR annealed cobalt-doped NiOX (NIR-Co:NiOX) was synthesized to replace pristine NIR-NiOX. The PCE of PVSCs fabricated from this new NiOX film can be increased from 15.99% to 17.77%, which is due to the efficient hole extraction, less charge accumulation, and reducing Voc loss resulting from the improved hole mobility, reduced interface resistance and well-matched work function. Our study paves a way to fulfill the requirements of low cost and low energy consumption of large scale production of high efficiency PVSCs.

Different oxidation states of copper(I, I/II, II) thiocyanate complexes containing 1,2,4-triazole as a bridging ligand: Syntheses, crystal structures

Copper thiocyanate compounds with three different oxidation states, CuI(admtrz)SCN (1), [CuI2CuII(admtrz)6 (SCN)2]-(ClO4)2 (2), and [CuII3(admtrz)4(SCN)3 (mu3-OH)(H2O)](ClO4)2 ·H2O (3), have been synthesized and characterized (admtrz = 4-amino-3,5-dimethyl-1,2,4-triazole). Compounds 1 and 3 crystallize in the space group Pbca of the orthorhombic system with eight formula units in cells of dimensions a = 8.0221(2) A, b = 32.3844(1) A, c = 13.5659(3) A, R1/wR2 = 0.0595/0.1674 for compound 1 and a = 21.501(3) A, b = 18.382(2) A, c = 21.526(2) A, R1/wR2 = 0.0638/0.1519 for compound 3. Compound 2 crystallizes in the space group C2/c of the monoclinic system with four formula units in cells of dimensions a = 18.772(4) A, b = 11.739(2) A, c = 22.838(5) A, beta = 91.11(3), R1/wR2 = 0.0482/0.1265. The layered-type structure of 1 can be regarded as constructed from the tetranuclear copper units double bridged by one of the two unique thiocyanate and admtrz ligands, which are bridged by the other unique thiocyanate ligands to form a two-dimensional layered structure along the a and b directions. The linear trinuclear copper cation in mixed-valence compound 2 consists of one two-valence copper and two one-valence copper atoms which are bridged by admtrz ligands, and the external copper(I) atoms are coordinated by terminal thiocyanate. The EPR spectra of 2 show the existence of localized mixed-valence copper ions. The triangle trinuclear copper cation in compound 3 has its Cu3 triangle capped by one apical mu3-OH group, each edge bridged by a bridging admtrz ligand and each Cu atom coordinated by a N atom from the terminal thiocyanate, while one of the three edges is further bridged by another admtrz ligand and the opposite Cu1 atom is coordinated by a water molecule. The EPR and magnetic susceptibility of compound 3 were studied, showing antiferromagnetic behavior.
