Compound: 435294-03-4, is researched, Molecular C35H27N2O2Ir, about The width of exciton formation zone dominates the performance of phosphorescent organic light emitting diodes, the main research direction is phosphorescent organic light emitting diode current efficiency.Product Details of 435294-03-4.

Abstract: Phosphorescent organic light emitting diodes (PHOLEDs) have been fabricated with structure of indium tin oxide/MoO3 doped 4,4′-N,N’-dicarbazole-biphenyl (CBP) 30 nm/tris(4-carbazoyl-9-ylphenyl)amine 10 nm/CBP doped with tris(2-phenylpyridine)iridium(III) (CBP:Ir(ppy)3) x/bathocuproine 50 nm/LiF 1 nm/Al, where x = 2.5, 5, 10, and 20 nm, resp. The current efficiency (CE) of device with x = 10 nm is higher than those with x = 2.5 and 5 nm, mostly because the width of exciton formation zone (5.7 nm) with x = 10 nm is larger than those (2.5 and 5 nm) with x = 2.5 and 5 nm. However, the c.d. with x = 10 nm decreases than those with x = 2.5 and 5 nm at a certain driving voltage, since the ∼ 4.3 nm CBP:Ir(ppy)3 accommodating no exciton formation with x = 10 nm plays a role of transporting holes, raising ohmic loss of hole and thereby increasing driving voltage. When x increases from 10 to 20 nm, the width of exciton formation zone rises from 5.7 to 6.8 nm with CE almost unchanged, and the c.d. decreases as a result of increased ohmic loss of hole. The current research is useful to develop high-efficiency and low-driving voltage PHOLEDs.

Formula: C10H24N2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, is researched, Molecular C10H24N2, CAS is 111-18-2, about Cyclodextrin modified, multication cross-linked high performance anion exchange membranes for fuel cell application. Author is Ma, Lingling; Qaisrani, Naeem Akhtar; Hussain, Manzoor; Li, Lv; Jia, Yabin; Ma, Siyu; Zhou, Ruiting; Bai, Lei; He, Gaohong; Zhang, Fengxiang.

The anion exchange membranes (AEMs) with high hydroxide ion conductivity and stability are in an urgent need for alk. membrane fuel cell applications. High ionic exchange capacity (IEC) is necessary to improve conductivity but detrimental to stability. In this work, a series of novel AEMs modified with bulky rigid β-cyclodextrin (CD) and long flexible multiple quaternary ammonium (MQ) are designed and prepared The resulting AEM with a relatively low IEC of 1.50 mmol g-1 shows a good hydroxide ion conductivity of 112.4 mS cm-1 at 80 oC, whereas its counterpart without CD modification exhibits 83.0 mS cm-1 despite a similar IEC (1.60 mmol g-1); this is because the large CD units can impart high free volume to the membrane, reducing the ion transport resistance, and meanwhile, the hydrophilicity of CD′s external surface may promote formation of ion transport channels across the long flexible MQ cross-links. The CD modified AEM also imparts the membrane a better alkali- and swelling resistance as well as a higher tensile strength, without sacrificing its hydroxide ion conduction properties, than the un-modified membrane. The H2-O2 fuel cell yields a high peak power d. of 288 mW cm-2 at 60 oC. Our work implies that the CD enabled free volume strategy is effective to balance conductivity and stability, which may pave the way to fabrication of AEMs with further improved performance.

Computed Properties of C10H24N2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms.

Author is Long, Chuan; Wang, Zhihua; Zhu, Hong.

In recent years, ether-free polyaryl polymers prepared by superacid-catalyzed Friedel-Crafts polymerization have attracted great research interest in the development of anion exchange membranes(AEMs) due to their high alkali resistance and simple synthesis methods. However, the selection of monomers for high-performance polymer backbone and the relationship between polymer structure construction and properties need further investigated. Herein, a series of free-ether poly(aryl piperidinium) (PAP) with different polymer backbone steric construction were synthesized as stable anion exchange membranes. Meta-terphenyl, p-terphenyl and diphenyl-terphenyl copolymer were chosen as monomers to regulate the spatial arrangement of the polymer backbone, which tethered with stable piperidinium cation to improve the chem. stability. In addition, a multi-cation crosslinking strategy has been applied to improve ion conductivity and mech. stability of AEMs, and further compared with the performance of uncrosslinked AEMs. The properties of the resulting AEMs were investigated and correlated with their polymer structure. In particular, m-terphenyl based AEMs exhibited better dimensional stability and the highest hydroxide conductivity of 144.2 mS/cm at 80°C than other membranes, which can be attributed to their advantages of polymer backbone arrangement. Furthermore, the hydroxide conductivity of the prepared AEMs remains 80%-90% after treated by 2 M NaOH for 1600 h, exhibiting excellent alk. stability. The single cell test of m-PTP-20Q4 exhibits a maximum power d. of 239 mW/cm2 at 80°C. Hence, the results may guide the selection of polymer monomers to improve performance and alk. durability for anion exchange membranes.

Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 92-71-7, is researched, Molecular C15H11NO, about Search for reactor neutrino directionality using a LAB-based Gd-loaded liquid scintillation detector, the main research direction is gadolinium neutrino liquid scintillation.Product Details of 92-71-7.

Recently, several interesting phenomena related to neutrinos have been found using reactor neutrinos and we have learned much about the properties of neutrinos. Ultrapure water or liquid scintillator is generally used to detect neutrinos. Since a detector filled with water can use the Cherenkov light emitted in a conical shape based on the direction of a charged particle, the direction of the incident neutrinos can be reconstructed relatively well. However, in a detector filled with the liquid scintillator, the reactor neutrino signal can be reconstructed using information from the Inverse Beta Decay (IBD) process. In this case, it is not easy to determine the direction of an incident neutrino because light is emitted in all directions. In this study, we briefly investigated the possibility of the directional reconstruction of reactor neutrinos in the Linear Alkyl Benzene (LAB)-based Gadolinium (Gd)-loaded liquid scintillator using a Monte Carlo simulation technique. The LAB was used in place of existing, conventional liquid scintillation detector solution It has a high flash point and is environmentally friendly. The purpose of this study was to show a practical and interesting application of neutrino direction reconstruction for reactor neutrinos that could be used in future large liquid scintillator neutrino detectors.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Effects of small-molecule-doping on spin-assisted processes in P3DDT:PC61BM photovoltaics, published in 2020-09-30, which mentions a compound: 92-71-7, Name is 2,5-Diphenyloxazole, Molecular C15H11NO, Application of 92-71-7.

The effect of the 1,2-benzopyrone (BP) and 2,5-diphenyloxazole (PPO, DPO) additives on the formation, separation, motion, and recombination of charge carriers in the poly(3-dodecylthiophene):[6,6]-phenyl-C61-butanoic acid Me ester (P3DDT:PC61BM) organic photovoltaics was investigated by the light-induced ESR (LEPR) and NIR-Vis-UV spectroscopy within the wide temperature and photon energy range. These processes were interpreted in the framework of the exchange interaction of spin ensembles differently distributed in bulk heterojunctions of the P3DDT:PC61BM composite. The concentration, composition, and dynamics of spin charge carriers were shown to be determined by the modification degree of the sample with small mols., the energy of the light photons as well as the number, spatial distribution and energetic depth of spin traps formed in the disordered polymer matrix. Electronic functionality of the composite becomes better after its doping with BP and PPO additives up to optimal weight levels of 0.03 and 0.06, resp. Such modification can improve the morphol./ordering of the composite that increases the number of highly mobile charge carriers due to the release of a part of carriers captured by energetically deep spin traps. This increases an exchange interaction between spin ensembles, reduces the number and depth of electron spin traps that, in turn, prevents the recombination of charge carriers and accelerates the power conversion.
