Thin layers of nonlinear optical 4'-nitrobenzylidene-3-acetamino-4-methoxy-aniline (MNBA) were grown heteroepitaxially by organic molecular beam epitaxy (OMBE) on the b-plane of lattice-matched single crystals of the organic salt ethylenediammonium terephthalate (EDT). Epitaxy was realized ...

A one-pot solvent-free synthesis of N-methyl imines in good to excellent yields was performed by grinding together aromatic aldehydes and methylamine hydrochloride in the presence of a base. The best yields were achieved when an excess of methylamine hydrochloride and inexpensive sodium hydrogen...

The photochemistry of dinitronaphthalenes (1,3-, 1,4-, 1,5-DNN), 4,4′-dinitrobiphenyl (DNB) and 2,7-dinitrofluorenone (DNF) in benzene at room temperature was studied by time-resolved UV-Vis spectroscopy after ns laser pulses at 354 nm. The triplet states of the five dinitro compounds, 3∗O2NArN...

The benzylidene-aniline derivative with an electron-donating group at the 4-position and an electron-accepting group at the 4′-position has been suggested, by MO calculations, to have a small molecular dipole moment in spite of the large second-order hyperpolarizability, and hence to be a promi...

Synthesis, growth, X-ray crystal structure and characterization of a novel third order nonlinear optical material, 4-methoxy-4′-dimethylamino-benzylidene aniline (MDMABA), are reported for the first time. The asymmetric unit of MDMABA compound contains two crystallographically independent molec...

Ionic diamine rhodium complexes catalyze the reductive N-heterocyclization of N-(2-nitroarylidene)amines under carbon monoxide to afford the corresponding 2H-indazoles in up to 75% yields.

5-(2-(4-Methoxyphenyl)ethyl)-2-amino-3-methylcarboxylate thiophene (TR560) is the prototype drug of a recently discovered novel class of tumor-selective compounds that preferentially inhibit the proliferation of specific tumor cell types (e.g. leukemia/lymphoma). Here, we further increased tumor...

Adsorption of 5-alkyl derivatives of 3-amino-1,2,4-triazole and their effect on the passivation of copper have been studied in neutral buffer solution using polarization, ellipsometric and XPS techniques. Triazoles are capable of forming passive layers on the copper surface at very low concentra...

A series of 5-substitutedbenzylideneamino-2-butylbenzofuran-3-yl-4-methoxyphenyl methanones is synthesized and evaluated for antileishmanial and antioxidant activities. Compounds 4f (IC50 = 52.0 ± 0.09 µg/ml), 4h (IC50 = 56.0 ± 0.71 µg/ml) and 4l (IC50 = 59.3 ± 0.55 µg/ml) were shown signi...

The combination of experimental (inhibition of colchicine binding) and computational (COMPARE, docking studies) data unequivocally identified diaryl 5-amino-1,2,4-oxadiazoles as potent tubulin inhibitors. Good correlation was observed between tubulin binding and cytostatic properties for all tes...

In this study, we synthesized a novel poly(ether-ether-ketone), containing di(quaternary ammonium) hydroxide groups in the polymer chain. Then we tested the alkaline–exchange properties of a membrane made from the novel polymer, for fuel-cell applications. First, we synthesized a di-hydroxide m...

In the present study, the structural parameters of 209 types of polymethoxylated diphenyl ethers (PMeODEs), 209 types of polyhydroxylated diphenyl ethers (PHODEs), seven types of methoxylated-polychlorinated diphenyl ethers (MeO-PCDEs) and seven types of hydroxylated-polychlorinated diphenyl eth...

We report an effective and simplified procedure for the synthesis of cross-linked alkaline anion-exchange membranes (AEMs). A new monomer containing two tertiary amine groups on 4,4′-dihydroxydiphenyl ether (DABPE) is used in nucleophilic aromatic substitution step-growth copolymerization with ...

Effect of polyamide and poly(arylene ether) as backbones of bis(benzene sulfonyl)imide for single ion conducting polymer electrolytes on mechanical and electrochemical properties and device performance was investigated. Alternating copolymerization between 4,4′-fluorine bis(benzene sulfonyl)imi...

Despite the introduction of restrictive regulations in the USA and the European Union, polybrominated diphenyl ethers (PBDEs) are still found in various types of environmental and biological samples at significant concentration levels. The presence of these persistent organic pollutants in the e...

A route for cleaving the C–O aryl ether bonds of p-substituted H–, CH3–, and OH– diphenyl ethers has been explored over Ni/SiO2 catalyst at very mild conditions (393 K, 0.6 MPa). The C–O bond of diphenyl ether is cleaved by parallel hydrogenolysis and hydrolysis (hydrogenolysis combined wit...

Acid catalyzed alkylation of 4,4′-dihydroxydiphenyl ether with isobutylene gives rise to two isomeric tetraalkyl derivatives (I, II). The oxidation of the symmetrically substituted derivative (I) occurs with elimination of the ether oxygen. The unsymmetrically substituted isomer (II) yields by ...

The main aim of this work was to conduct the preliminary/basic research concerning the preparation process of a new dummy molecularly imprinted polymer (DMIP) materials. Developed DMIPs were proposed as a sorption material in solid-phase extraction (SPE) technique for recognition of selected low...

The diphenyl ether degrading bacterial strain Sphingomonas sp. SS3, although not able to utilize 4-hydroxy- and 4,4'-dihydroxydiphenyl ether as sole sources of carbon and energy, is nevertheless capable of transforming these diaryl ethers into mononuclear hydroxylated aromatic compounds. Th...
