Ultra-high transparent p-type copper iodide (CuI) thin films were fabricated by solid iodization of evaporated Cu precursor layers at room temperature. The effect of the thickness on microstructure, binding energy and optoelectrical properties is systematically studied. X-ray diffraction measurements show the polycrystalline nature of the CuI thin films with zincblende type structure. The X-ray photoelectron spectroscopy (XPS) analysis indicates that the oxidation state of Cu is +1 and the estimated value of [Cu]/[I] at 100 nm is 0.87. Excess iodide ions trap considerable holes, causing CuI thin films to exhibit the p-type conductivity, which is consistent with the results of the Hall effect measurement and the non-linear characteristics of the CuI/ITO structure. Moreover, the CuI thin films with thickness of 100 nm exhibits an ultra-high optical transmittance of 95.5% in the wavelength of 380?780 nm and an excellent conductivity of 34 S/cm. These results prove the great potential of CuI as a promising p-type optoelectronic material.

The sterically bulky di(1-adamantyl)benzylphosphane (L) reacts with the copper(I) compounds, CuX (X = Cl, Br, I and SCN), in a 1:1 ratio to give the salts CuXL. Single crystal X-ray structures for X = Cl, Br and SCN, show that the complexes exist as dimeric species of the type [Cu2X2L2] with the X groups bridging to give each copper a distorted trigonal-planar coordination geometry with a ?PX2? donor site. When [Cu(CH3CN)4]BF4reacts with L in a 1:2 ratio, the two-coordinated complex [CuL2]BF4was formed which has a P?Cu?P angle of 169.46(6), reflecting the influence of the adamantyl groups. The silver(I) 1:2 compound, [AgClL2], has a ?ClP2? donor set with a distorted P?Ag?P bond angle of about 149.02(5). The reduced coordination numbers, irregular structures and distortions of selected angles are a result of the steric bulk (large cone angle) of L. Some of these structural features may also assist in understanding why Pd(0) complexes of L are effective catalysts for the Sonogashira coupling reactions of arylchlorides and alkynes.

A new method is proposed for measuring the antioxidant capacity by electron spin resonance spectroscopy based on the loss of electron spin resonance signal after Cu2+ is reduced to Cu+ with antioxidant. Cu+ was removed by precipitation in the presence of SCN-. The remaining Cu2+ was coordinated with diethyldithiocarbamate, extracted into n-butanol and determined by electron spin resonance spectrometry. Eight standards widely used in antioxidant capacity determination, including Trolox, ascorbic acid, ferulic acid, rutin, caffeic acid, quercetin, chlorogenic acid, and gallic acid were investigated. The standard curves for determining the eight standards were plotted, and results showed that the linear regression correlation coefficients were all high enough (r > 0.99). Trolox equivalent antioxidant capacity values for the antioxidant standards were calculated, and a good correlation (r > 0.94) between the values obtained by the present method and cupric reducing antioxidant capacity method was observed. The present method was applied to the analysis of real fruit samples and the evaluation of the antioxidant capacity of these fruits. (Graph Presented).

The unrestricted Hartree-Fock (UHF) and hybrid-density functional theory (DFT) calculations have been carried out for the metal oxides such as copper oxides and nickel oxides. In order to elucidate magnetic properties of the species, the effective exchange integrals (Jab) have been obtained by the total energy difference between the highest and lowest spin states in several computational schemes with and without spin projection. The mixing ratios of the exchange correlation functionals in the hybrid DFT method have been reoptimized so as to reproduce the Jab values for strongly correlated oxides. The natural orbital analysis has also been performed for elucidation of symmetry and occupation numbers of the magnetic orbitals. From these calculated results, we discuss characteristics of the magnetic interactions for metal oxides in the strong correlation regime.
