We synthesized and characterized the non-peripherally and peripherally tetra-substituted manganese (III) phthalocyanines (3) and (4) containing [4-(2-methoxyethyl)phenoxy] group. Synthesized compounds were characterized by standard spectroscopy methods. The crystallographic information and stabi...
Along with the development of molecular electronics and spintronics, how to realize logic operation in nanoscale molecular devices has been a key issue. Thus it is essential to achieve basic logic gates in a small scale, which are the fundamental elements of digital circuits. By using nonequilib...
As an alternative to rare, expensive noble metal based electrocatalysts, cost-effective metal phthalocyanines having high availability and bearing unique properties, shows their remarkable footprint as a suitable electrocatalyst in oxygen reduction reaction. We report in the present work, the ch...
A mimic enzymeless electrochemical sensor (M-Eless-ES) based on the terminal alkynyl substituted manganese phthalocyanine (MnPc-TA) and 4-azido polyaniline (N3-PANI) hybrid was constructed and tested as a selective and sensitive pesticide sensor. A new electrode modification technique, solid sta...
A procedure for simultaneous solvent extraction of Cu(II) and Fe(III) from river surface waters as diethyldithiocarbamates (DDC) 1,1,1-trifluoroacetylacetonates into isobutyl methyl ketone (IBMK) has been developed prior to their determination by flame atomic absorption spectrometry. Experimenta...
X-ray photoelectron spectroscopic measurements of copper complexes of biochemical significance were carried out to permit the conclusion whether or not copper is present in the Cu(I) or Cu(II) state. Only one single homogeneous signal in the X-ray photoelectron spectra of the Cu(I) 2p12 and 2p32...
When the conventional gas Chromatographic method with helium as carrier gas is used, thorium(IV) trifluoroacetylacetonate shows an anomalous peak and the chelate is not eluted quantitatively. But, by using trifluoroacetylacetone vapour as a carrier-gas additive, the anomalous peak can be improve...
The complexes Cu4OCI6(Ph3P)4 · 0.5Et2O, Cu4OCl6(Ph3As)4, Cu4OCl6(Ph3As)4 · Et2O, Cu4OCl6(MeOH)2(Ph3As)2, Cu4OCl6(Ph3Sb)4 · Et2O and Cu4OBr6(Ph3P)4 · 1.5Et2O were prepared and isolated. The electronic and IR spectra indicate a tetrameric structure with trigonal bipyramidal coordination of the...
Electronic structures and magnetic properties of Cu(II) complexes with axially coordinated nitronyl nitroxide radicals are discussed on the basis of computational study using density functional theory (DFT) calculation. The tendency of the effective exchange integrals J is examined by changing t...
The copper-catalyzed enantioselective monoarylation of meso-1,2-diols by the use of diaryliodonium triflates as aryl sources has been developed. The chiral copper(II) complex catalyzed the asymmetric desymmetrization effectively to afford optically active β-aryloxy alcohols in moderate to high ...
An improved method for the asymmetric alkylation of 3-bromooxindoles with α-arylated malonate esters is described. The asymmetric alkylation demonstrated was achieved up to 70% ee utilizing a copper(II) bis(phosphine) complex.
Copper (I) or copper (II) salts and oxides promote regioselective head-to-head additive dimerization of aromatic and aliphatic terminal alkynes in the presence a catalytic amount of diethylphosphite. The reaction proceeds under ambient conditions without any added base with the formation of 1,4-...
An X-ray photoelectron spectroscopy study of the charge and spin state of copper(II) β-diketonates and Cu(hfa)2 (hfa–hexafluoroacetylacetonate) complexes with imidazoline ligands is performed with comparison to the data of quantum chemical calculations. It is shown that the structure of the sp...
In this work, the hybrid copper inks with precursor and nanoparticles were fabricated and sintered via flash light irradiation to achieve highly conductive electrode pattern with low porosity. The hybrid copper ink was made of copper nanoparticles and various copper precursors (e.g., copper(II) ...
The electrochemical behavior of the N,N-dialkyldithiocarbamate pesticide thiram at a Au microdisk electrode (10 μm φ) and at cylindrical carbon fiber microelectrodes (CFMEs) (8 μm φ, 8 mm length) in low-permitivity organic solvents such as toluene and ethyl acetate is reported. The obtained ...
A procedure has been developed for the determination of ziram (zinc dimethyldithiocarbamate), ferbam (ferric dimethyldithiocarbamate) and zineb (zinc ethylenebisdithiocarbamate) after their decomposition and extraction of the diphenylcarbazone complexes of the zinc or iron into isobutyl methyl k...
The neurotoxicity of dithiocarbamates has been previously reported, however, the detailed mechanism underlying the neurotoxicity is still not fully understood. Among the dithiocarbamates, we investigated thiram and ziram in a neuronal-like pheochromocytoma (PC12) cells. Thiram and ziram strongly...
Ziram is a dimethyldithiocarbamate fungicide which can cause intraneuronal calcium (Ca2+) dysregulation and subsequently neuronal death. The signaling mechanisms underlying ziram-induced Ca2+ dyshomeostasis and neurotoxicity are not fully understood. NCX3 is the third isoform of the sodium–calc...
The existence and characterization of cis and trans isomers of Pd(NH3)2Cl2 have been re-investigated. A stable monoclinic trans compound has been prepared at low temperature. It has been shown that when trans-Pd(NH3)2Cl2 is prepared at room temperature or above, it is a mixture of monoclinic and...
Three new cadmium(II)-metal(II) cyanide complexes, [Cd(4aepy)2(H2O)2][Ni(CN)4] (1), [Cd(4aepy)2(H2O)2][Pd(CN)4] (2) and [Cd(4aepy)2(H2O)2][Pt(CN)4] (3) [4aepy = 4-(2-aminoethyl)pyridine], have been synthesized and characterized by elemental, thermal, FT-IR and Raman spectral analyses. The crysta...
