A series of polyamic acid copolymers (co-PAAs) with para-hydroxyl groups was synthesized using two diamine monomers, namely p-phenylenediamine (p-PDA) and 5-amino-2-(2-hydroxy-5-aminobenzene)-benzoxazole (m-pHBOA), of different molar ratios through copolymerization with 3,3,4,4-biphenyltetracarboxylic dianhydride (BPDA) in N,N-dimethyacetamine (DMAc). The co-PAA solutions were used to fabricate fibers by dry-jet wet spinning, and thermal imidization was conducted to obtain polyimide copolymer (co-PI) fibers. The effects of the m-pHBOA moiety on molecular packing and physical properties of the prepared fibers were investigated. Fourier transform infrared (FTIR) spectroscopic results confirmed that intra/intermolecular hydrogen bonds originated from the hydroxyl group and the nitrogen atom of the benzoxazole group and/or the hydroxyl group and the oxygen atom of the carbonyl group of cyclic imide. As-prepared PI fibers displayed homogenous and smooth surface and uniform diameter. The glass transition temperatures (T(g)s) of PI fibers were within 311-337 degrees C. The polyimide fibers showed 5% weight loss temperature (T-5%) at above 510 degrees C in air. Two-dimensional wide-angle X-ray diffraction (WXRD) patterns indicated that the homo-PI and co-PI fibers presented regularly arranged polymer chains along the fiber axial direction. The ordered molecular packing along the transversal direction was destroyed by introducing the m-pHBOA moiety. Moreover, the crystallinity and orientation factors increased with increasing draw ratio. Small-angle X-ray scattering (SAXS) results showed that it is beneficial to reduce defects in the fibers by increasing the draw ratio. The resultant PI fibers exhibited excellent mechanical properties with fracture strength and initial modulus of 2.48 and 89.73 GPa, respectively, when the molar ratio of p-PDA/m-pHBOA was 5/5 and the draw ratio was 3.0.

A variety of functional groups were tolerated and heteroaryl nitriles were also suitable substrates. Preliminary mechanistic studies indicated a ring-opening mechanism.

In the present work we report the electrochemical characterization of self-assembled monolayers (SAMs) of N, O-heteroaromatic thiols, namely benzoxazole-2-thiol (1), naphthaleneoxazole-2-thiol (2) and anthraceneoxazole-2-thiol (3) on polycrystalline gold electrodes. SAMs were formed by immersion of pre-treated gold electrodes into ethanolic solutions of the title compounds. The modified electrodes exhibited a decrease of electroactivity, as found by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), in comparison to bare electrodes according to the length of the aromatic p-system. In addition, reductive desorption experiments confirmed that of the three compounds, 3 formed the most stable SAMs in agreement with EIS measurements which revealed better blocking properties against the redox couple in a test electrolyte indicating a charge transfer determined behaviour in the case of longer molecules. The charge transfer resistances revealed a trend towards higher resistances in the case of 3. When performing EIS at various starting potentials and different electrolyte concentrations, it was found that at certain critical potentials (E-crit) a potential-induced structural change of the SAM occurred, with E-crit(1) > E-crit(2) > E-crit(3). In the case of SAMs of 3 the nature of this alteration was investigated via scanning tunnelling microscopy and found to presumably be caused by an order-disorder-transition. (C) 2018 Elsevier Ltd.

Inflammatory responses are generated against the danger molecules under normal conditions but excessive or chronic inflammation leads to tissue degeneration and loss of function. To prevent the disease symptoms associated with the inflammatory disorders or the growth of tumor types that require inflammatory environment, generation of immunomodulatory drugs with suppressive functions have great potentials. In this study, we synthesized new generation of anti-proliferative bis-benzoxazole derivatives and tested their anti-inflammatory and anti-cancer potencies. For this purpose, we used a well-characterized mouse macrophage cell line (RAW 264.7). Furthermore, anti-cancer activity of these compounds were tested using MTT assay on prostate (DU145) and breast (MCF7) cancer cells. The screening results revealed that all compounds possessed a high-level anti-inflammatory potential by reducing the expression of inflammatory cytokines in LPS-stimulated macrophages. There were significant and substantial reductions in the secreted TNF alpha, IL6, and IL1 beta levels by chemically treated LPS-induced macrophages compared to non-treated induced ones. Our compounds exerted their anti-inflammatory effect in a dose-dependent manner and they were biologically active even in low nanomolar range concentrations. Bis-benzoxazole derivatives had anti-proliferative effect on MCF-7 and DU-145 cancer cells. Together, our results present a series of new bis-benzoxazole-based compounds with potential therapeutic effects in inflammatory diseases and on tumor cells.

New Advances in Chemical Research in 2021. Catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 540-36-3, Name is 1,4-Difluorobenzene, molecular formula is , belongs to benzoxazole compound.

The present work is devoted to the synthesis and detailed investigation of new 8-benzothiazole containing spiropyrans. The investigated spiropyrans exist under colorless spirocyclic isomers exhibiting positive photochromism with thermo- and photoinduced back reaction. UV light irradiation leads to their effective coloration with quantum yields up to 44%. The efficiency of the back photocyclization induced by visible light does not exceed 0.1%. This feature distinguishes them from the previously studied benzoxazole analogs. The enhancement of electron-withdrawing properties of the indoline fragment substituents promotes an increase in photo-coloration efficiency. The lifetime of the colored form varies from 17 to 200.8 s (acetone, 293 K) depending on substituents. Due to the presence of the benzothiazole moiety, merocyanines can effectively bind Zn2+, Co2+, Ni2+, Cu2+, Cd2+, Mn2+ ions. The addition of salts of these ions to spiropyran solutions results in the stabilization of the merocyanine in the form of intensely colored complexes. Composition, stability and spectroscopic characteristics of complexes have been investigated depending on the metal ion nature and substituents in ligand molecules. The colored complexes possess negative photochromism. The visible light irradiation causes their bleaching with quantum yields up to 48%. The benzothiazole substituted spimpyrans demonstrate ion driving photochromic transformation.

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.

Two luminescent pseudo-polymorphs based on a new cuprous complex, [Cu(2-iQBO)(POP)]PF6 (2-iQBO = 2-(1′-isoquinolyl)benzoxazole, POP = bis[2-(diphenylphosphino)phenyl]ether), have been synthesized and characterized by UV-Vis, elemental analysis and single-crystal X-ray diffraction analyses. The pseudo-polymorphs 1 and 2 are characterized as a dichloromethane solvate and an acetonitrile solvate, respectively. Single-crystal X-ray diffraction data reveal that 1 and 2 are both mononuclear cuprous complexes with a tetrahedral CuN2P2 coordination configuration, consisting of two P atoms from the POP ligand and two N atoms from the 2-iQBO ligand. The pseudo-polymorphic complexes 1 and 2 can be distinguished by their crystal color, UV-Vis spectra and PL spectra. Time-dependent density functional theory (TD-DFT) calculations reveal that the P-Cu-P angle is a key structural factor influencing the absorption and emission properties. Based on the TD-DFT calculations, the lowest singlet excited state corresponding to the UV-Vis absorption edge can be definitely assigned as a metal-to-ligand charge transfer (MLCT) mixed with a ligand-to-ligand charge transfer (L’LCT), and the lowest triplet excited states should be both assigned as a mixed (3)(ML + L’L)CT character.
