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.

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.

Herein, we report the fabrication of multiwalled carbon nanotube (MWCNT) conjugates of cobalt phthalocyanines (CoPcs) with peripherally substituted Flavone (flay) or benzoxazole (bo) groups. The CoPc-X-f-MWCNT (X = flay or bo) conjugates were characterized by Transmission Electron Microscopy (TEM) and Infrared (IR) spectroscopy. The respective nanocomposite materials were drop-casted onto the surfaces of glassy carbon electrodes (GCEs) and the resultant chemically modified electrodes (CMEs) were used as electrocatalytic detectors for acetaminophen. Under optimized conditions, the peak currents for CoPc-flay-f-MWCNTs- and CoPc-bo-f-MWCNTs- GCEs were linear in wide acetaminophen concentration ranges of 1-1000 mu M and 15-1000 mu M, respectively. Electron transfer kinetics of the CMEs were superior than the bare electrode where diffusion- and convection-controlled electrocatalytic constants in the order of 10(2) and 10(4) M-1 s(-1) were obtained for both the CMEs. The CMEs showed good selectivity for APAP when tested in the presence of other emerging water pollutants. Electrochemical impedance spectroscopic experiments provided an insight into the mechanism of electrocatalysis occurring at the interfaces of the CMEs. (C) 2019 Elsevier B.V. All rights reserved.

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.

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.

A rigidification strategy was applied to the preclinical candidate donecopride, an acetylcholinesterase inhibitor possessing 5-HT4R agonist activity. Inspired by promising bioactive benzisoxazole compounds, we have conducted a pharmacomodulation study to generate a novel series of multitarget directed ligands. The chemical synthesis of the ligand was optimized and compounds were evaluated in vitro against each target and in cellulo. Structure-activity relationship was supported by docking analysis in human acetylcholinesterase binding site. Among the synthesized compounds, we have identified a novel hybrid 32a (3-[2-[1-(cyclohexylmethyl)-4-piperidyl]ethyl]-4-methoxy-1,2-benzoxazole) able to display nanomolar acetylcholinesterase inhibitory effects and nanomolar Ki for 5-HT4R.

Unnatural alanine derivatives bearing a benzoxazole moiety at the side chain, acting simultaneously as the coordinating and reporting unit, via fluorescence changes, were synthesised with a furan ring at position 2, substituted with different (hetero)aryl substituents, in order to tune the photophysical and chemosensory properties of the resulting compounds. The amino acid derivatives were prepared in protected form at their N- and C-termini with tert-butoxycarbonyl urethane and methyl ester protecting groups, respectively. The novel furyl-benzoxazol-5-yl-l-alanines were evaluated for the first time in the recognition of several transition metal cations with environmental, medicinal and analytical interest such as Co2+, Cu2+, Zn2+ and Ni2+, in acetonitrile solution. The spectrofluorimetric titrations showed that the novel benzoxazolyl-alanines 3a-g were sensitive, although not selective, fluorimetric chemosensors for the above mentioned cations, with the best result being obtained for N,N-diethylamino substituted alanine 3d in the sensing of Cu2+. The heterocyclic system at the side chain was identified as the key factor in the recognition event of the metal cations, through its electron donor atoms. The encouraging photophysical and metal ion sensing properties of these furyl-benzoxazolyl-alanines suggest that they can be used to obtain bioinspired fluorescent reporters for metal ions such as peptides/proteins with chemosensory/probing abilities.

The reaction of 2,6-bis(benzoxazolyl)-4-tert-butylphenol (HL) with [(BuxSnCl4-x)-Bu-n] (x = 0, 1) in 1:1 stoichiometry yielded the tin coordination complexes [(HL)(SnBuxCl4-x)-Bu-n] [x = 0 (1); x = 1 (2)]. Deprotonation of HL was performed using reagents having groups with high basicity such as (BuLi)-Bu-n or [Sn{N(SiMe3)(2)}(2)]. These basic reagents prompted the coordination of the ligand in its anionic form, yielding the complexes [(thf)(2)Li(L)SnCl4] (3) and [(L)Sn{N(SiMe3)(2)}] (4), respectively. The molecular structure of HL displayed an intramolecular hydrogen bond OH-N and a planar arrangement of the bis(benzoxazolyl)phenolic system. In the molecular structures of both complexes containing HL an intramolecular hydrogen bond of NH-O type was also present. The coordination of the ligand in either neutral or anionic form is described by a kappa O,kappa N chelate mode toward Sn. All complexes displayed bis(benzoxazolyl)phenolic moieties close to planar; the least planar system was observed in 4 that was also studied by DFT methods. [GRAPHICS] .

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.
