High temperature membranes based on PBI/sulfonated polyimide and doped-perovskite nanoparticles for PEM fuel cells

A new sulfonated aromatic diamine monomer containing nitrogen heterocycles was synthesized and employed to prepare a novel sulfonated polyimide (SPI). To develop proton exchange membranes, new nanocomposite blend membranes consist of the prepared SPI and polybenzimidazole (PBI) were fabricated with incorporation of SrCe0.9Yb0.1O3-delta (SCYb) doped-perovskite nanoparticles with a solution-casting method. The goal of this work is to study the effect of SPI and SCYb doped-perovskite nanoparticles on the important parameters of the PBI membrane specially proton conductivity and fuel cell performance. The proton conductivity and phosphoric acid doping level of the PBI-SPI-SCYb nanocomposite blend membranes improved due to an interaction of -SO3H group and thiazole rings of SPI and N-H groups of PBI in the oxygen vacancies of SCYb doped-perovskite nanoparticles. Substitution of Ce4+ by Yb3+ in the SCYb doped-perovskite nanoparticles produce oxygen vacancies and decrease the columbic repulsion between protons and positive ions. Furthermore at highest phosphoric acid doping level of 14 mol phosphoric acid per monomer unit, the nanocomposite blend membranes displayed proton conductivity of 131 mS/cm at 180 degrees C and 8% relative humidity. The increase in power density from 0.31 W/cm(2) in PBI-SPI blend membranes (SPI/PBI: 25 wt%) to 0.59 W/cm(2) in PBI-SPI-SCYb nanocomposite blend membranes (SPI/PBI: 25 wt% and 7 wt% of SCYb) was achieved at 0.5 V, 8% RH and 180 degrees C, which demonstrates that these developed nanocomposite blend membranes have a high potential to be regarded as the most promising candidates for high-temperature fuel cell with improved proton conductivity.

Facile synthesis of novel fluorescent thiazole coumarinyl compounds: Electrochemical, time resolve fluorescence, and solvatochromic study

In this study, Benzocoumarin-Thiazoles-Azomethine derivatives with bioactive scaffolds were synthesized and characterized. The present investigation is concerned with the multistep synthesis of thiazole coumarinyl derivatives (5a-k), which were accomplished from naphthaldehyde, ethyl acetoacetate, and thiosemicarbazide. The formation of newly synthesized derivatives was confirmed by H-1 NMR and C-13 NMR spectroscopic studies. Thiazole coumarinyl derivatives were subjected to UV-Visible studies in different solvents such as ethanol, ethyl acetate, and DMF for solvatochromic studies. The synthesized coumarinyl thiazole compounds showed absorption in the range of 332-390 nm. Electrochemical studies were performed in DMSO and redox behavior was offered by thiazoles. Fluorescence of coumarinyl thiazole compounds were examined in ethanol, ethyl acetate, and DMF to visualize the solvent effect on the emitting ability of compounds. Fluorescence spectra of coumarinyl thiazoles expressed a sharp emission in the range 436-550 nm. (C) 2020 Elsevier B.V. All rights reserved.

Breaking the axiality of pentagonal-bipyramidal dysprosium(iii) single-molecule magnets with pyrazolate ligands

A range of pyrazolate-based ligands have been used to balance the multidentate-chelating feature and the magnetic axiality in destroyed pentagonal-bipyramidal (DPB) dysprosium(iii) single-molecule magnets (SMMs). This family of complexes are air-stable and share the general formulae of [(DyXX2)-X-1(L-eq)(5)][BPh4], where X-1 and X-2 are the anionic axial ligands, including pyrazolate-based ligands and chloride; L-eq is the equatorial solvent molecule such as tetrahydrofuran (THF), pyridine (py) and thiazole (NS). Compared to the prototype PB SMMs, the bidentate-chelating features of the pyrazolate ligands show, albeit slow magnetic relaxation behavior, a much smaller energy barrier for magnetization reversal (U-eff). Static electronic calculation shows that the magnetic axiality above the ground m(J) = +/- 15/2 states has been much reduced, leading to the mixing of other states at higher levels. Nevertheless, this systematic study reveals that the variation of the substituents on the pyrazolate ligands and the replacement of planar solvents are effective at influencing the magnetic relaxation behavior. We found that the chloride coordinating mono-pyrazolate complexes, such as [(DyXCl)-Cl-1(THF)(5)][BPh4] (X-1 = 3-(trifluoromethyl)pyrazole (tfpz) 1, X-1 = 3-methylpyrazole (Mepz) 2, X-1 = 3-isopropyl-1H-pyrazole (Iprpz) 3, X-1 = 3,5-dimethylpyrazole (Me(2)pz) 4, X-1 = 3,5-diisopropylpyrazole (Ipr(2)pz) 5, and X-1 = pyrazole (pz) 6, generally show lower U-eff, while bi-pyrazolate complexes, such as [Dy(tfpz)(2)(THF)(5)][BPh4] 7, [Dy(pz)(2)(THF)(5)][BPh4] 8, [Dy(pz)(2)(py)(5)][BPh4]center dot 2py 9 and [Dy(pz)(2)(NS)(5)][BPh4] 10, show higher U-eff. Among them, 8 shows the largest U-eff of 521(8) K and a comparable open hysteresis temperature of similar to 5 K (at a field sweeping rate of 12 Oe s(-1)) with 9 and 10. The enhanced blocking temperature for 8 is different from that for the PB Dy(iii) SMMs in which the py ligand can cause a much higher hysteresis temperature than the one coordinated with THF due to the aromatic pi-pi interactions, indicating that the bis-bidentate-chelating Dy(iii) ion is rigid enough to reduce the influence from the equatorial ligands. Moreover, substitution with electron-withdrawing groups such as the -CF3 group reduces U-eff prominently. Such a clear magnetostructural correlation in Dy(iii) SMMs is fundamentally important, indicating that a subtle balance between magnetic axiality and molecular rigidity is critical to design high-performance Dy(iii) SMMs.

New Aspects of Monoamine Oxidase B Inhibitors: The Key Role of Halogens to Open the Golden Door

A large plethora of drugs and promising lead compounds contain halogens in their struc-tures. The introduction of such moieties strongly modulates their physical-chemical features as well as pharmacokinetic and pharmacodynamic profile. The most important outcome was shown to be the ability of these halogens to favourably influence the drug-target interaction and energetic stability within the active site by the establishment of halogen bonds. This review attempted to demonstrate the key role exerted by these versatile moieties when correctly located in an organic scaffold to display Monoamine Oxidase (MAO) inhibition and selectivity towards the B isoform of this important enzyme. Human MAOs are well-recognized as therapeutic targets for mood disorders and neurodegenerative diseases and medicinal chemists were prompted to discover the structural requirements crucial to discriminate the slight differences between the active sits of the two isoforms (MAO-A and MAO-B). The analysis of the structure-activity relationships of the most important scaffolds (hydrazothia- zoles, coumarins, chromones, chalcones, pyrazolines) and the impact of halogen (F, Cl, Br and I) insertion on this biological activity and isozyme selectivity have been reported being a source of inspiration for the medicinal chemists.

Application of 96-53-7, 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 96-53-7 is helpful to your research.

Co(II) coordination polymers constructed from a bent chiral linker: influencing framework topology using co-ligands

A semi-rigid chiral ligand (1R, 2R)-4,4′-(trans-cyclohexane-1,2-diyl)bis(azanediyl)bis(carbonyl) dibenzoic acid (H(2)cbba) was combined with various Co(II) salts and dipyridyl co-ligands to obtain four 2D homochiral coordination polymers of composition [Co(cbba)(dipyridyl)]center dot solvate (dipyridyl = 4,4′-bipyridyl (bipy), bis(4-pyridyl)ethylene (bpe), 1,4-bis(4-pyridyl)benzene (1,4-bpb), 2,5-bis(4-pyridyl)thiazolo [5,4-d]thiazole (2,5-bptztz)) (1-4). The topology of the frameworks is mediated by the length of the co-ligands, with short dipyridyl co-ligands (4,4′-bipy and bpe) resulting in the formation of (4(13).6(2)) networks (1-2), while long co-ligands (1,4-bpb and 2,5-bptztz) led instead to (4(4).6(2)) (sql) networks that undergo 2D -> 2D parallel interpenetration to form a rare example of a homochiral polyrotaxane (3-4). The length of the dipyridyl co-ligand was also found to have an effect on the conformation of the flexible cbba(2-) ligands and the crystal packing of the networks.

Thiazolo[5,4-d]Thiazole-Based Donor-Acceptor Covalent Organic Framework for Sunlight-Driven Hydrogen Evolution

2D covalent organic frameworks (COFs) could have well-defined arrangements of photo- and electro-active units that serve as electron or hole transport channels for solar energy harvesting and conversion, but their insufficient charge transfer and rapid charge recombination impede the sunlight-driven photocatalytic performance. We report a new donor-acceptor (D-A) system, PyTz-COF that was constructed from the electron-rich pyrene (Py) and electron-deficient thiazolo[5,4-d]thiazole (Tz). With its bicontinuous heterojunction, PyTz-COF demonstrated exceptional optoelectronic properties, photocatalytic ability in superoxide anion radical-mediated coupling of (arylmethyl)amines and photoelectrochemical activity in sunlight-driven hydrogen evolution. Remarkably, PyTz-COF exhibited a photocurrent up to 100 mu A cm(-2) at 0.2 V vs. RHE and could reach a hydrogen evolution rate of 2072.4 mu mol g(-1) h(-1). This work is paving the way for reticular design of highly efficient and highly active D-A systems for solar energy harvesting and conversion.
