Membrane technology operating in highly concentrated solutions is essential in pressure retarded osmosis (PRO) applications to compete with other renewable energy technologies. Herein, we fabricated highly porous and robust electrospun membranes (ESMs) using a poly(benzoxazole-co-imide) (PBO) polymer. For the first time in osmotic-driven systems, novel one-step direct fluorination was adopted to increase hydrophilicity of the ESM. Direct fluorination increased the total surface energy of the ESM by boosting polar surface energy parameter, which eventually affected the formation of ‘ridge & valley’-like thin film composite membrane (PBO-TFC-F5) through interfacial polymerization of the fluorinated ESM. As a result, PBO-TFC-F5 achieved an unprecedented power density of 87.2 W m(-2) using 3 M NaClaq as a draw solution at 27 bar. When PBO-TFC-F5 was used for osmotic heat engine (OHE), it showed a power generation cost of only 203 $center dot MWh(-1), which was less than half the cost observed using commercial membranes. This robust, porous, and high performance PBO-TFC-F5 opens up new possibilities in membrane-based power generation systems.

Why do aromatic interactions matter? In this blog, let’s explore why it’s so important to understand aromatic interactions using C16H9Br as examples. Electric Literature of 1714-29-0

Thermal rearrangement of a-functional polyimide membranes into poly(benzoxazole) improves the permselectivity performance compared to the precursor polymer. This is due to the bimodal cavity size distribution generated through the TR process. The cavity volume can be further increased by including segments within the polyimide that undergo degradation at a lower temperature than the TR process. The loss of these segments leaves behind cavity space that can be used to increase gas permeability. This is achieved here for copolymers based on 4,4′-hexafluoroisopropylidene diphthalic anhydride (6FDA) and 3,3′-dihydroxy-4,4′-diamino-biphenyl (HAB) with poly (ethylene glycol) segments, where the PEG segments undergo thermal degradation below the PI to PBO transition temperature. HAB-6FDA-PEG copolymer membranes, with different weight % PEG, had poor permselectivity for CO2-N-2 and CO2-CH4 separation. Undertaking thermal treatment to degrade the PEG segments but retaining the PI polymer resulted in an increased fractional free volume of the resulting membrane and higher gas permeability, but a corresponding loss of CO2 selectivity. Producing TR-PBO from the copolymers through thermal rearrangement at 450 degrees C, improved the gas permeability of the resulting membranes by over an order of magnitude, as well as improving the CO2 selectivity. This was attributed to the degradation of the PEG segments increasing the FFV of the membranes, resulting in over a third of the polymers’ morphology being free volume. The resulting TR-PBO membranes formed from copolymers with PEG segment had enhanced permselectivity performance compared to TR-PBO formed from the polyimide homopolymer.

A series of methacrylamides containing benzoxazole (BO) mesogenic side groups and different lengths of alkyl units was synthesized in this study. A methacrylamide containing the n-dodecyl group was selected as a suitable monomer to obtain beneficial thermally conductive polymeric materials because of its sufficient solubility in toluene in the subsequent radical polymerization and because of its liquid crystallinity. This methacrylamide led to a highly soluble polymer with film-forming ability. The BO-containing polymethacrylamide also exhibited liquid-crystalline (LC) behavior during the heating and cooling processes. The cast film was kept at a slightly lower temperature than the clearing temperature and quenched to room temperature. This procedure afforded a film maintaining optical anisotropy at room temperature, implying that a frozen LC structure is maintained at room temperature. The quenched film also resulted in a significantly enhanced thermal conductivity (lambda = 0.60 W m(-1) K-1) without the aid of fillers and external fields, unlike the as-cast counterpart without optical anisotropy. A polyacrylate containing a flexible long alkylene (C-6) spacer between the main chains and a BO-containing mesogenic side group was also investigated. The polyacrylate exhibited LC behavior during the heating and cooling processes over wide ranges. The polyacrylate film quenched from an established temperature, which contains a frozen LC structure, also exhibited a significantly enhanced lambda value (0.63 W m(-1) K-1) without fillers and external fields. Thus, the BO-containing vinyl polymers studied in this work are promising candidates for novel heat-releasing materials. (c) 2020 Society of Chemical Industry

We report the effect of replacing the pyridine group in the chelating trz Ir water oxidation catalysts by a benzoxazole and a thiazole moiety. We have also evaluated if the presence of bidentate ligands is crucial for high activities and to avoid the decomposition into undesired heterogeneous layers. The catalytic performance of these benzoxazole/thiazole triazolidene Ir-cornplexes in water oxidation was studied at variable pH using either CAN (pH = 1) or NaI04 (pH = 5.6 and ‘7). Electrocatalytic experiments indicated that while CAN-mediated water oxidation led to catalyst heterogeneization irrespective of the triazolylidene substittient, periodate as sacrificial oxidant preseived a homogeneously active species. Repetitive additions of sacrificial oxidant indicates higher integrity of the Ir-complex with a thiazolesubstituted triazolylidene compared to ligands featuring a benzoicazole as chelating of the thiazole group was also established from stability measurements under conditions.

The π-electrons of these planar compounds are free to cycle around the circular arrangements of atoms found in the aromatic moieties. This stems from the resonance found in planar ring systems, like benzene, and C16H9Br. Computed Properties of https://www.ambeed.com/products/1714-29-0.html.

As the most studied and widely used chiral ligands, C16H9Br have been rapidly developed in recent decades due to their simple synthesis, easy modification, and the ability to achieve excellent results in multiple reactions. Formula: https://www.ambeed.com/products/1714-29-0.html.

The excited-state intramolecular proton transfer (ESIPT) process of 6-amino-2-(2 ‘-hydroxyphenyl) benzoxazole (6A-HBO) was investigated using density functional theory and time-dependent density functional theory methods with B3LYP and TZVP basis sets. n-Heptane, dichloromethane, methanol, and acetonitrile were chosen as a series of polar solvents in calculations using the IEFPCM model. To obtain a more comprehensive ESIPT mechanism, we constructed the S-0 and S-1 states’ potential energy surfaces (PESs) by incrementally twisting the OH bond and increasing the distance of O-H bond. Based on the analysis of the bond lengths, the IR vibrational spectra, and the frontier molecular orbits (MOs), the intramolecular hydrogen bonding (OH…N) is clearly strengthened, and the charge is redistributed in the S-1 state. The results of calculated absorption spectrum are in accord with the experimental data. The fluorescence spectrum of 6A-HBO-enol showed a normal red shift, but the red shift of the 6A-HBO-keto is larger and increases with the solvent polarity, indicating a charge transfer. Analysis of the PESs indicates a lower potential energy barrier in S-1 state for the proton transfer from the O atom to the N atom, with the excited state potential barrier slightly decreasing with the increase of the solvent polarity.

Reaction of 2-(2′-pyridyl)benzoxazole (2-PBO) or 2-(4′-pyridyl)benzoxazole (4-PBO) ligands with CuSCN afforded two thiocyanate copper (II) complexes, Cu(2-PBO) (SCN)(2) (1) and Cu(4-PBO)(2)(SCN)(2) (2), have been characterized by elemental analysis, UV-Vis, IR spectra and single-crystal X-ray diffraction. The structural analysis reveals that although the structures of complexes 1-2 are both four coordinated and show plane quadrilateral structure, the distorted of complex 1 is greater than 2. The cyclic voltammogram of complexes 1-2 represent quasi-reversible Cu2+/Cu+ pairs. The superoxide radical scavenging test in vitro showed that complex 1-2 had significant antioxidant activity on superoxide radicals, and the activity of complex 2 was higher than that of 1. This may be due to the structure of complex 2 being closer to the Cu, Zn-SOD. (C) 2018 Elsevier B.V. All rights reserved.

This research investigates the dynamic excited state process for a novel system 2-(2-dihydroxyphenyl) benzoxazole (DHBO) for excited state proton transfer (ESPT) process based on density functional theory (DFT) and time-dependent DFT (TDDFT) methods. Because 2 intramolecular hydrogen bonds (O-1?H2N3 and O-4?H5O6) in DHBO molecules may trigger proton transfer process in the S-1 state, we focus on these 2 hydrogen bonds. Our results show that only the O-1?H2N3 bond has obvious changes in both bond length and bond angle upon photoexcitation. Charge redistribution also confirms that hydrogen bond wire (O-1?H2N3) is the best way to achieve the ESPT process in the S-1 state. Considering the ESPT mechanism, our theoretical potential energy curves of DHBO indicate that only the excited state single-proton transfer process occurs via O-1?H2N3 rather than O-4?H5O6. We believe that our work not only clarifies the excited state dynamical behavior of DHBO but also promotes the investigations about ESPT reactions in intramolecular or intermolecular hydrogen bonded chemical systems.

As a GSK-3 beta inhibitor reported by our group, K313 is a novel benzoxazole derivative and displays anti-inflammatory properties in RAW264.7 macrophages without cytotoxicity. The activity of GSK-3 beta affects the differentiation and maturation of bone marrow-derived dendritic cells (DCs). This study aims to investigate whether K313 can be used to induce regulatory/tolerogenic dendritic cells (DCregs), and the therapeutic effects of DCregs induced by K313 in the autoimmune model of experimental autoimmune encephalitis (EAE). The results show that compared with LPS stimulated mature DCs, K313-treated bone marrow-derived DCs display obvious tolerogenic characteristics with decreased expression of co-stimulatory molecules, downregulated secretions of pro-inflammatory cytokines and unregulated secretion of anti-inflammatory cytokine IL-10. The above characteristics conform to the typical phenotypes of DCregs. Moreover, K313-modified DCregs inhibit antigen-specific T cell responses in vitro. Furthermore, by adoptive transfer, K313 modified DCregs to the EAE mice, and the development of disease was ameliorated to some extent. In addition, treatment with K313-modified DCregs also significantly reduced the percentages of splenetic Th1 and Th17 cells and increased the percentage of regulatory T cells in EAE mice. In conclusion, K313-modified DCregs show anti-inflammatory properties in vitro and have a significant positive effect on the EAE disease in vivo. Our data indicate that K313-induced DCregs pulsed with auto-antigen might have potential use as a therapeutic approach for autoimmune inflammation of the central nervous system.
