A biradical oxo-molybdenum complex containing semiquinone and o-aminophenol benzoxazole-based ligands

We report a new mononuclear molybdenum(iv) complex, (MoOLLSQ)-L-BIS, in which L-SQ (2,4-di-tert-butyl o-semibenzoquinone ligand) has been prepared from the reaction of the o-iminosemibenzoquinone form of a tridentate non-innocent benzoxazole ligand, L-BIS, and MoO2(acac)(2). The complex was characterized by X-ray crystallography, elemental analysis, IR and UV-vis spectroscopy and magnetic susceptibility measurements. The crystal structure of (MoOLLSQ)-L-BIS revealed a distorted octahedral geometry around the metal centre, surrounded by one O and two N atoms of L-BIS and two O atoms of L-SQ. The effective magnetic moment (mu(eff)) of (MoOLLSQ)-L-BIS decreased from 2.36 to 0.2 mu(B) in the temperature range of 290 to 2 K, indicating a singlet ground state caused by antiferromagnetic coupling between the metal and ligand centred unpaired electrons. Also, the latter led to the EPR silence of the complex. Cyclic voltammetry (CV) studies indicate both ligand and metal-centered redox processes. (MoOLLSQ)-L-BIS was applied as a catalyst for the oxidative cleavage of cyclohexene to adipic acid and selective oxidation of sulfides to sulfones with aqueous hydrogen peroxide.

Fluorescence sensing response of zinc(II) and pyrophosphate ions by benzoxazole appended dipodal Schiff base

A novel benzoxazole appended dipodal Schiff base (BS) was synthesized and its sensing property was investigated. The receptor BS detected Zn2+ ions selectively by turn-on fluorescence among the wide range of metal ions in DMSO-H2O (1:9 v/v, 50 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) at pH 7.4. The different physicochemical parameters of BS-Zn2+ complex were investigated by UV-vis, photoluminescence, H-1 NMR titration and ESI-MS techniques. The limit of detection (LOD) and binding constant (K-b) of BS-Zn2+ complex have been determined by fluorescence titration and found to be 4.53 x 10(4) M-1 and 0.52 mu M. Moreover, binding ratio of BS and Zn2+ was found to be 1:1 by Job’s method. Further, the BS-Zn2+ complex was used to sense pyrophosphate (PPi) ions as a secondary sensor in HEPES buffer solution. Overall, the sensitive fluorescence behavior of the receptor BS has been utilized as a powerful tracker for zinc ion and pyrophosphate ion in biological systems.

Red Emitting Hydroxybenzazole (HBX) Based Azo Dyes: Linear and Non Linear Optical Properties, Optical Limiting, Z Scan Analysis with DFT Assessments

Herein, we report the hydroxybenzazole (HBX) containing azo dyes for linear and non-linear optical (NLO) applications. These bi-heterocyclic dyes have HBX scaffold (decorated with ESIPT core) and connected to another thiazole moietiy through azo bond. In DMF and DMSO, dyes are emissive in yellow-red region and large Stokes shift in the range of 62-121 nm were observed. Nonlinear absorptive coefficient (beta), nonlinear refractive index (n(2)), third order non-linear optical susceptibility (chi(3)) in DMSO, ethanol and methanol were calculated using simple and effective Z-scan technique having Nd: YAG laser at 532 nm wavelength. 4.46 x 10(-13) (e.s.u.) was the highest (chi(3)) was observed in DMSO among all the dyes. Optical Limiting (OL) values are in the range of 7.61-19.06 J cm(-2) in solvents. Thermo Gravimetric Analysis (TGA) supports that, these compounds are useful for numerous high-temperature practices in the construction of electronic as well as optical devices. Band gap was calculated by CV as well as by DFT in acetonitrile. The same trend was observed when these HOMO-LUMO gaps were correlated in between CV and DFT. To gain more insights into structural parameters, molecular geometries were optimized at B3LYP-6-311 + G (d,p) level of theory. Further, Molecular Electrostatic Potential (MEP), Frontier Molecular Orbitals (FMO) were presented using Density Functional Theory (DFT). Global hybrid functional (B3LYP, BHandHLYP) and range separated hybrid functionals (RSH) i.e. CAM-B3LYP, omega B97, omega B97X, and omega B97XD were used to calculate linear and NLO properties.

Molecularly imprinted covalent organic polymers for the selective extraction of benzoxazole fluorescent whitening agents from food samples

Molecularly imprinted covalent organic polymers were constructed by an imine-linking reaction between 1,3,5-triformylphloroglucinol and 2,6-diaminopyridine and used for the selective solid-phase extraction of benzoxazole fluorescent whitening agents from food samples. Binding experiments showed that imprinting sites on molecularly imprinted polymers had higher selectivity for targets compared with those of the corresponding non-imprinted polymers. Parameters affecting the solid-phase extraction procedure were examined. Under optimal conditions, actual samples were treated and the eluent was analyzed with high-performance liquid chromatography with diode-array detection. The results showed that the established method has a wide linearity, satisfactory detection limits and quantification limits, and acceptable recoveries. Thus, this developed method possesses the practical potential for the selective determination of benzoxazole fluorescent whitening agents in complex food samples.

Validated High Performance Liquid Chromatographic Quantification of Pamidronate in Bulk and Dosage Form

Aims: The studied drug is lacking the presence of chromophore so a reaction with NBD-Cl is optimized to facilitate its chromatographic detection, so the main aim of the work is to quantify pamidronate in a sensitive and accurate way either in bulk or dosage forms. Methodology: The quantification of this group of drugs is a challenging task as they lack the presence of chromophore groups in their structure. The proposed method depends on the chromatographic quantification of the studied drug after its derivatization via its reaction with 4-Chloro-7-nitro-2,1,3-benzoxazole and the product is separated on ODS C18 column (5 mu m, 15 cm x 5 mm, i.d.) as a stationary phase and methanol : water (8:2, v/v) as a mobile phase. The flow rate was 1 ml/min. Results: The studied drug can be determined in the range of 900 – 3000 ng/mL after optimizing the assay conditions to get optimum stationary – mobile phases match. Method validation is performed according to USP-guidelines and different validation parameters like, linearity, accuracy, precision and robustness are calculated and found to be excellent.

New Coumarin-benzoxazole derivatives: Synthesis, photophysical and NLO properties

In this work, a series of novel D-pi-A structure coumarin-benzoxazole derivatives have been synthesized. The third-order NLO properties of the coumarin derivatives in DMSO are investigated by Z-scan measurement, and the photophysical properties of the compounds are studied through experimental and theoretical calculation methods. The results showed that the introducing specific functional groups at multiple active sites of coumarin reduced the pi-pi intermolecular stacking, while the formation of push-pull structure decreased E-gap of entire molecule. The excellent third-order NLO responses based on chromophore 4c with maximum nonlinear absorptive coefficients is 50.64 x 10(-13) esu and the largest second-order NLO hyperpolarizability is 7.12 x 10(-30) esu. Experimental results have also been confirmed through DFT, TDDFT and ZINDO calculations. Our results indicate that the coumarin fluorescent dyes are promising candidate materials for NLO applications.

Two luminescent pseudo-polymorphic cuprous complexes with different optical properties: Synthesis, characterization and TD-DFT calculations

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.
