Herein, we compare the electrochemical and electrocatalytic properties of two selected, water-insoluble Fe(II) coordination complexes made with the non-symmetric, bidentate ligands, 2-(2′-pyridyl)benzimida zole (PBI) in [Fe(PBI)(3)](OTf)(2) (1, OTf- = trifluoromethyl sulfonate anion) and 2-(2′-pyridyl)benzoxazole (PBO) in [Fe(PBO)(2)(OTf)(2)] (2). Cyclic voltammetry in water/acetonitrile mixture indicates considerable activity for both compounds. However, only 1 acts as homogeneous catalyst. The complexes have been successfully immobilized on indium-tin-oxide (ITO) electrode surface. The hydrophobic ligands allowed for a simple dip-coating and drop-casting of 1 and 2 onto ITO. Both 1/ITO and 2/ITO showed increased activity in electrocatalytic O-2 evolution in borate buffer at pH 8.3. According to scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), moreover, re-dissolution tests, the Fe remains in complex with PBI during electrolysis in the drop-casted, nano-porous films of 1/ITO. In contrast, the PBO complex in 2/ITO undergoes a rapid in situ decomposition yielding a mineralized form that is responsible for catalysis. (C) 2019 The Author(s). Published by Elsevier Inc.

Herein, we synthesized a series of twelve benzoxazole and benzothiazole derivatives incorporated with phthalimide core as anticancer agents. The most active compounds were 5a and 5g against HepG2 and MCF7 cell lines with IC50 = 0.011 and 0.006 mu M, respectively. They evaluated against EGFR and HER2 enzymes. From cell cycle analysis, it was observed that test compounds exerted pre G1 apoptosis and cell cycle arrest at G2/M phase. The achieved results suggested that apoptosis was due to activation of caspase-7 and caspase-9. EGFR was chosen as a biological target for carrying molecular modeling study for the newly synthesized compounds.

The unprecedented reaction of tertiary amines with 2(3H)-benzoxazolones has been investigated. In the presence of the Ph3P-I-2 reagent system, the reaction of both acyclic and cyclic aliphatic tertiary amines led to the formation of 2-N,N-dialkylaminobenzoxazoles with the selective cleavage of an alkyl group. Especially, N-(2-iodoethyl)piperazinyl derivatives were rapidly produced in good yields when using DABCO as the nitrogen source. Only in the cases when the nucleophilicity of the substrates exceeds that of the amine, competitive self -condensation of benzoxazolones then proceeds preferentially. P-31{H-1}-NMR study suggested the involvement of an aryloxyphosphonium intermediate and/or possibly 2-iodobenzoxazole which activates the C-2 position of benzoxazolones toward nucleophilic aromatic substitution.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 108-32-7, in my other articles.

The ability of two-component dyeing photoinitiating systems for the radical polymerization of 1,6-hexanediol diacrylate (HDDA) and 2-ethyl-2-(hydroxymethyl)-1,3-propanediol triacrylate (TMPTA) is presented. The systems under study comprised a hemicyanine dye as a sensitizer and iodonium salts that played a role of a coinitiator. The kinetic parameters of the polymerization reaction, such as the rate of polymerization (R-p) and the degree of conversion of monomer (C-%), were estimated. The thermodynamic feasibility of an electron transfer process in the systems studied was verified and calculated using the Rehm-Weller equation. It was found that a benzoxazole derivative in the presence of iodonium salts effectively initiated the polymerization of acrylate monomers. The polymerization rates of about 10(-7) s(-1) and the degree of conversion of acrylate groups from 20% to 50% were observed. The effects of photoinitiator structures on the initiating ability and spectroscopic properties of sensitizers are described in this article.

The solubility of 2,2’-(1,2-ethenediyldi-4,1-phenylene) bis-benzoxazole (OB-1) in four monosolvents (chlorobenzene, N-methyl-2-pyrrolidone (NMP), N,N-dimethylformamide (DMF), and water) and four different binary solvents (chlorobenzene-DMF, NMP-water, DMF-water, and chlorobenzene-NMP) was measured by a dynamic method at temperatures ranging from 323.15-383.15 K under an atmospheric pressure of 0.101 MPa. The experimental data shows that the solubility of fluorescent agent OB-1 increases with an increase in temperature in both the pure and binary solvents. The solubility of the fluorescent agent OB-1 in four pure solvents increases in the following order: chlorobenzene > NMP > DMF > water. The modified Apelblat equation, lambda h equation, nonrandom two-liquid (NRTL) model, and Wilson equation were used to correlate the experimental data, and the experimental solubility and correlation equations in this work can be used as essential data and models in the industrial manufacture process of OB-1.

TBET-based ratiometric fluorescent probe for Hg2+ with large pseudo-Stokes shift and emission shift in aqueous media and intracellular colorimetric imaging in live Hela cells

The detection of Hg2+ in biological systems and its imaging is of highly importance. In this work, a novel ratiometric fluorescence probe is developed based on through-bond energy transfer (TBET) with a 2-(2-hydroxyphenyl)benzoxazole (HBO) as donor and a Rhodamine derivative-Hg conjugate (RDM-Hg) as acceptor. Hg2+ weakens the fluorescence of HBO at 430 nm and meanwhile interacts with Rhodamine B derivative to form a fluorescent conjugate (RDM-Hg) giving rise to emission at 597 nm with a 167 nm red-shift. Further, the difference 282 nm between the donor absorption (315 nm) and the accepter emission (597 nm) for 1 + Hg2+ is comparable to the highest value of the Stokes shift (282 nm) reported earlier for other reported TBET-based cassette. Through-bond energy transfer from HBO to RDM-Hg is triggered by Hg2+ resulting in concentration dependent variation of fluorescence ratio I-597/I-430. A linear calibration of I-597/I-430 versus Hg2+ concentration is obtained within 0-5 mu M, along with the lowest detection limit being found to be as low as 1.31 x 10(-9) mol center dot l(-1) (similar to 0.26 ppb) for Hg2+. This feature is further demonstrated by colorimetric imaging of test strip and intracellular Hg2+. On the other hand, the HBO/RDM TBET sensing system is characterized by a combination of high sensitivity and selectivity. The present study provides an approach for further development of ratiometric probes dedicated to selective in vitro or in vivo sensing some species of biologically interest.

Polyimides in membrane gas separation: Monomer’s molecular design and structural engineering

Polyimides (PIs) are an important, well-established, and commercialized class of polymers due to their extraordinary physical and chemical properties. They have been extensively applied as membrane fabrication materials for gas separation, especially in natural gas upgrading and acidic CO2 gas removal from industrial off-gases. However, two major unsolved challenges still remain for P1-based membranes: overcoming the trade-off relationship between the gas permeability and selectivity, and maintaining the long-term operational performance through controlling thermal and pressure conditioning, physical and chemical ageing, plasticization, swelling, permeation hysteresis, and resistance against impurities or presence of trace contaminants. This review aims to explore practical procedures to give the best insights into synthesis of efficient PI-based gas separation membranes as well as introducing advanced modification methods that have been applied for available PIs in view of obtaining a superior performance. A comprehensive structure to-property relationship is elaborated by molecular design and engineering of PI monomers, i.e., the assembly of sub-objects: diamine and dianhydride monomers. This approach covers all issues from atom, functional group, segment (micro-structure or molecular design) to branch, chain and network assembly of the PIs. Detailed discussions include substitution positions, halogenated groups, bridging functional groups, bulky groups (linear and branched and subdivided into silyl and germyl, fluorine, methyl, iptycene and Troger’s Base groups). Moreover, criteria for designing high quality hyperbranched polyimides (HB-PI), co-polyimides (co-PIs) including polyamide-imides, polyether-imide, triptycene based co-PIs, multi block co-PIs, and hyper-branched co-PIs are presented. Cross-linked PIs are also discussed by classifying them according to the methods of reaction: thermal, UV, and chemical cross-linking (abbreviated by TCL, UVCL, and CCL, respectively). An additional issue in this regard, i.e., the hyper cross-linked polyimides, HCLPs, is discussed as well. (C) 2019 Elsevier B.V. All rights reserved.
