Synergetic Effect of Iron-Doped Acidic Multi-Walled Carbon Nanotubes in the Synthesis of Diverse Substituted Five-Membered Heterocyclic Compounds

Iron-doped acidic multi-walled carbon nanotubes (Fe@acidic-MWCNs) were synthesized using the chemical vapor deposition (CVD) process in the presence of acetylene and ferrocene as the sources of carbon and iron nanoparticles, respectively. The Fe@acidic-MWCNs was fully characterized by inductively coupled plasma (ICP), X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), Raman, and FT-IR analysis. In continuation, the synergetic effect of iron nanoparticles and acidic groups of the Fe@acidic-MWCNs was studied through the synthesis of substituted five-membered heterocyclic compounds including 2-substituted benzimidazoles, 2-substituted benzothiazoles, 2-substituted benzoxazoles, and 1-substituted tetrazoles. Moreover, the 2-substituted benzimidazoles were investigated by two different methods. In general, Fe@acidic-MWCNs catalyst showed good to excellent catalytic activity. Finally, the Fe@acidic-MWCNs catalyst displayed a high reusability and stability in the synthesis of 3 a, 5 a, 7 a, 9 a, and 11 a.

Application of 76-37-9, 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 76-37-9 is helpful to your research.

Natural Born Laser Dyes: Excited-State Intramolecular Proton Transfer (ESIPT) Emitters and Their Use in Random Lasing Studies

A series of five excited-state intramolecular proton transfer (ESIPT) emitters based on a 2-(2 ‘-hydroxyphenyl) benzoxazole (HBO) scaffold, functionalized with a mono-or bis-(trialkylsilyl) acetylene extended spacer are presented. Investigation of their photophysical properties in solution and in the solid-state in different matrix, along with ab initio calculations gave useful insights into their optical behavior. Random lasing studies were conducted on a series of PMMA doped thin films, showing the presence of stimulated emission above the threshold of pumping energy density (rho th approximate to 0.5-2.6 mJ cm(-2)). In this work, the similarity of four level laser systems is discussed in light of the ESIPT photocycle.

Chromogenic properties of 2-(2-carbomethoxy-3,4-dichloro-6-hydroxyphenyl)benzoxazole and its Zn (II) and Cd(II) complexes

The chromogenic properties of 2-(2-carbomethoxy-3,4-dichloro-6-hydroxyphenyl)benzoxazole (1) were studied. Solvatochromism of 1 was observed at keto-enol equilibrium due to the ground state intramolecular proton transfer (GSIPT). It was found that solvents with a good hydrogen bond acceptor (beta) ability were able to stabilise the keto form of 1. The excited-state intra molecular proton transfer (ESIPT) in molecules of 1 resulted in intense fluorescence with an anomalous Stokes shift of up to 8493 cm 1 and quantum yields of 0.08-0.19. The keto-form of 1 exhibits negative T-type photochromism with a thermally reversible photoconversion to the enol form. The complexes of ligand 1 with Zn(II) and Cd(II) were synthesised. According to X-ray structural analysis, the zinc complex is the neutral complex, which is formed by two oxazole-N and two phenol O donors of ligand 1 which crystallise in a centrosymmetric group with the zinc ion located on the inversion centres. The synthesised complexes possess effective blue fluorescence and resistance to photodegradation.

Synthesis and photophysics of benzazole based triazoles with amino acid-derived pendant units. Multiparametric optical sensors for BSA and CT-DNA in solution

Herein we report the synthesis of a series of amino acid-derived triazoles by an organocatalytic cycloaddition reaction between azides and carbonyl compounds, catalyzed by a simple amine.These compounds present absorption maxima located in the UV-B ascribed to fully spin and symmetry allowed electronic transitions and a main fluorescence emission in the UV-A (similar to 380 nm) with a relatively large Stokes shift (5700 cm(-1)). No significant solvatochromism was observed in both ground and excited states. Unexpectedly, the benzoxazole derivatives presented much higher fluorescence quantum yield values (40-80%) of compared to the sulfur analogues (3-6%). In addition, the DNA binding assays indicated that these compounds presented strong interaction with CT-DNA, which could be attributed to pi-stacking and intermolecular hydrogen-bonding. The interaction of the benzazoles with bovine serum albumin (BSA) was also investigated, where a suppression mechanism was observed. In each case, docking was performed to better understand the observed interactions. (C) 2020 Elsevier B.V. All rights reserved.

Copper or Silver-Mediated Oxidative C(sp(2))-H/N-H Cross-Coupling of Phthalimide and Heterocyclic Arenes: Access to N-Arylphthalimides

Copper or silver-catalyzed direct C(sp(2))-H/N-H electrochemical cross-coupling of phthalimide and heterocyclic arenes (2-phenylpyridine, benzo[h]quinoline, benzoxazole, and benzothiazole, etc.) for the efficient synthesis of phthalimide derivatives is described. This reaction features good yield, mild conditions, and broad substrate scope, which provides an efficient and straightforward protocol to access this type of tertiary amines. For the first time, the proposed protocol is based not only on a copper catalyst but also on silver, which has never been used for this purpose before, and both give comparable results. Mechanistic investigations (voltammetry, ESR studies) disclosed that a free-radical pathway might be excluded in this process accomplished through Cu(I)/Cu(II)/Cu(III) or Ag(I)/Ag(III) cycles.

Thermally rearranged polybenzoxazole copolymers incorporating Troger’s base for high flux gas separation membranes

A new class of thermally rearranged (TR) polymers was prepared via copolymerization of TR-able o-hydroxyl polyimide and non-TR-able polyimide incorporating highly rigid Troger’s Base (TB) units. The effect of TB content, type of TR-able diamine, and TR protocols on polymer properties and gas transport behaviors were thoroughly studied. TB moieties in the copolymers efficiently enhanced polymer rigidity and induced high T-g and TR temperature as confirmed by thermogravimetric analysis and dynamic mechanical analysis. Additionally, as the TB molar ratio increased, the interchain distances of precursor polyimides increased from 0.545 to 0.585 nm. The most important finding in this work was the synergistic effect between TR conversion and TB segments, which provide the optimum contents of TB in the copolymers. As a result, 6F6FTB-0.3-450 presented a maximum d-spacing value of 0.609 nm and excellent gas separation performance of 1567 Barrer for H-2 and 1944 Barrer for CO2 along with a selectivity of 18.6 for H-2/CH4 and 23.07 for CO2/CH4, surpassing the corresponding 2008 upper bounds. In addition, 6F6FTB-0.3 exhibited good plasticization resistance under CO2/CH4 mixed gas up to CO2 fugacity of similar to 15 bar.

Correlation between beta-amyloid deposits revealed by BF-227-PET imaging and brain atrophy detected by voxel-based morphometry-MR imaging: a pilot study

Objective The purpose of this study was to investigate whether beta-amyloid (A beta) deposition was associated with local atrophy of corresponding areas in the brain. Methods [11C]2-[2-(2-Dimethylaminothiazol-5-yl) ethenyl-6-[2-(fluoro)ethoxy]benzoxazole (BF-227)-PET, MRI and neuropsychological tests were carried out on 56 subjects, out of which 21 were patients with Alzheimer’s disease (AD), 20 were patients with mild cognitive impairment (MCI) and 15 were normal controls (NC). The BF-227 uptake in each local brain region was set up with automated anatomical labeling atlas using Wake Forest University PickAtlas software and local standardized uptake value ratios of BF-227 were calculated as the average value of right and left using the MRIcron software. Results Group comparisons of A beta deposition as determined by BF-227 uptake using PET imaging showed no significant differences between MCI and AD. A beta deposition was significantly higher in MCI and AD than in NC. The correlation analysis between local A beta deposition and gray matter atrophy showed that in AD, the A beta deposition in the inferior temporal gyrus was strongly related to the gray matter atrophy in this region. On the contrary, the A beta deposition in the precuneus was associated with the atrophy in the right occipital-temporal region. In the NC, the A beta deposition in the inferior temporal gyrus was associated with the atrophy in the precuneus. Conclusion In the AD, the relationship between the A beta deposition and local atrophy is area-dependent. In NC, A beta deposition in the inferior temporal gyrus correlated to the atrophy in the precuneus.
