Transformation from Cu2-xS Nanodisks to Cu2-xS@CuInS2 Heteronanodisks via Cation Exchange

Cationic-exchange methods allow for the fabrication of metastable phases or shapes, which are impossible to obtain with conventional synthetic colloidal methods. Here, we present the systematic fabrication of heteronanostructured (HNS) Cu2-xS@CuInS2 nanodisks via a cationic-exchange reaction between Cu and In atoms. The indium-trioctylphosphine complex favorably attacks the lateral (16 0 0) plane of the roxbyite Cu2-xS hexagon. We explain the phenomena by estimating the formation energy of vacancies and the heat of reaction required to exchange three Cu atoms with an In atom via density functional theory calculations. In an experiment, a decrease in the amount of trioctylphosphine surfactant slows the reaction rate and allows for the formation of a lateral heterojunction structure of nanoplatelets. We analyze the exact structures of these materials using scanning transmission electron microscopy-energy dispersive X-ray spectroscopy and high-resolution transmission electron microscopy. Moreover, we demonstrate that our heteronanodisk can be an intermediate for different HNS materials; for example, adding gold precursors to a Cu2-xS@CuInS2 nanodisk results in a AuS@CuInS2 nanodisk via an additional cationic reaction between Cu ions and Au ions.

The structural definition of some novel adducts of stoichiometry CuX:dpex:MeCN (2:1:1)(n), X = (pseudo-) halogen, dppx = Ph2E(CH2)xEPh2, E = P, As, Sb

Single-crystal X-ray studies have defined the structures of a number of novel adducts of the form CuX:dpex (2:1), X = (pseudo-)halide, dpex = bis(diphenylpnicogeno)alkane, Ph2E(CH2)xEPh2, E = P, As, of diverse types, solvated with acetonitrile. CuBr:dpem (2:1)2. 2MeCN (E = both P, As) are tetranuclear, derivative of the familiar ‘step’ structure, while CuCl:dpph (MeCN solvate) and CuBr:dppe (MeCN solvate) yield one-dimensional polymers (i.e., x = 1, 2, 6 for dppx, x = m, e, h), as also does CuSCN:dpam (MeCN solvate). In CuI:dpsm:MeCN (3:1:2) (‘dpsm’ = Ph2Sb(CH2)SbPh2), CuI:dpsm (2:1)2 ‘step’ units are connected into an infinite ‘stair’ polymer by interspersed (MeCN)CuI linkers.

11% efficiency solid-state dye-sensitized solar cells with copper(II/I) hole transport materials

Solid-state dye-sensitized solar cells currently suffer from issues such as inadequate nano-pore filling, low conductivity and crystallization of hole-transport materials infiltrated in the mesoscopic TiO2 scaffolds, leading to low performances. Here we report a record 11% stable solid-state dye-sensitized solar cell under standard air mass 1.5 global using a hole-transport material composed of a blend of [Cu (4,4?,6,6?-tetramethyl-2,2?-bipyridine)2](bis(trifluoromethylsulfonyl)imide)2 and [Cu (4,4?,6,6?-tetramethyl-2,2?-bipyridine)2](bis(trifluoromethylsulfonyl)imide). The amorphous Cu(II/I) conductors that conduct holes by rapid hopping infiltrated in a 6.5 mm-thick mesoscopic TiO2 scaffold are crucial for achieving such high efficiency. Using time-resolved laser photolysis, we determine the time constants for electron injection from the photoexcited sensitizers Y123 into the TiO2 and regeneration of the Y123 by Cu(I) to be 25 ps and 3.2 ms, respectively. Our work will foster the development of low-cost solid-state photovoltaic based on transition metal complexes as hole conductors.

A Study of Copper Compounds by X-Ray Absorption Spectroscopy

Chemical shifts, DeltaE, of the K-absorption discontinuity in several compounds of copper possessing formal oxidation states between 0 and III have been measured.The shifts show a parabolic dependence on the formal oxidation state as well as on the effective atomic charge, q, on copper.Anomalous chemical shifts shown by some of the compounds are discussed in terms of the bonding in these compounds.The DeltaE values have also been correlated with the core electron binding energies obtained from X-ray photoelectron spectroscopy.

Facile synthesis of a hierarchical CuS/CuSCN nanocomposite with advanced energy storage properties

We introduce CuS/CuSCN nanocomposites as active materials in pseudocapacitors, in which the redox reactions of both CuS and CuSCN simultaneously contribute to energy storage. This nanocomposite is prepared using an in situ methodology via facile, low-energy-consuming green nanochemistry. The CuS/CuSCN nanocomposites offer a high capacitance compared to their individual constituents. CuS nanorods (?15 nm) are anchored on the surface of CuSCN nanosheets (?100 nm) and they interconnect the CuSCN nanosheets, producing mesoporous nanoclusters with a large surface area, thus improving the charge transfer efficiency. The CuS/CuSCN nanocomposites exhibit high electrical conductivity and strong redox reactivity, and in particular, the pseudocapacitor with a compositional ratio of 1:1 exhibits the highest charge transfer efficiency. Consequently, the 11 CuS/CuSCN active material exhibits a high energy density (approximately 63 W h kg-1) and a high power density (1.9 kW kg-1 at 9.0 W h kg-1) as a single electrode. The highest specific capacitance is measured to be 1787.3 F g-1 in the single electrode. Furthermore, an aqueous asymmetric hybrid supercapacitor based on the CuS/CuSCN 1:1//activated carbon (AC) shows an approximately four times increase in the power density (7.9 kW kg-1), compared to the single electrode.

Study of the Hole Transport Processes in Solution-Processed Layers of the Wide Bandgap Semiconductor Copper(I) Thiocyanate (CuSCN)

Wide bandgap hole-transporting semiconductor copper(I) thiocyanate (CuSCN) has recently shown promise both as a transparent p-type channel material for thin-film transistors and as a hole-transporting layer in organic light-emitting diodes and organic photovoltaics. Herein, the hole-transport properties of solution-processed CuSCN layers are investigated. Metal-insulator-semiconductor capacitors are employed to determine key material parameters including: dielectric constant [5.1 (¡À1.0)], flat-band voltage [-0.7 (¡À0.1) V], and unintentional hole doping concentration [7.2 (¡À1.4) ¡Á 1017 cm-3]. The density of localized hole states in the mobility gap is analyzed using electrical field-effect measurements; the distribution can be approximated invoking an exponential function with a characteristic energy of 42.4 (¡À0.1) meV. Further investigation using temperature-dependent mobility measurements in the range 78-318 K reveals the existence of three transport regimes. The first two regimes observed at high (303-228 K) and intermediate (228-123 K) temperatures are described with multiple trapping and release and variable range hopping processes, respectively. The third regime observed at low temperatures (123-78 K) exhibits weak temperature dependence and is attributed to a field-assisted hopping process. The transitions between the mechanisms are discussed based on the temperature dependence of the transport energy. The wide bandgap p-type semiconductor copper(I) thiocyanate (CuSCN) has the potential to replace conventional hole-transport materials in numerous opto/electronics applications. This work provides a comprehensive analysis of the charge transport properties of solution-processed CuSCN layers. Various techniques are employed to evaluate the dielectric constant, flat-band voltage, unintentional doping concentration, density of states in the mobility gap, and hole-transport mechanisms.

The metal complexes of 1-(phenylamino)-4, 4, 6-trimethyl-3, 4-dihydropyrimidine-2-(1H)-thione: Preparation, physical, spectroscopic studies and antibacterial properties

Objective: The metal complexes of 1-(Phenylamino)-4, 4, 6-trimethyl-3, 4-dihydropyrimidine-2-(1H)-thione: preparation, physical and spectroscopic studies and preliminary antibacterial properties. Methods: Complexes of bidentate ligand containing N, S-bridge [M(pmpt)2(H2O)n] (M(II) = Cu, Mn, Ni, Co; n = 2 and M(II) = Zn, Cd, Pd; n = 0) derived from the reaction of Hpmpt ligand with metals (M(II) = Cu, Mn, Ni, Co, Zn, Cd, Pd) and characterized by various physico-chemical techniques. From magnetic moment studies, square planar geometry is suggested for Zn(II), Cd(II), Pd(II) complexes, octahedral geometry is proposed for Co(II), Ni(II) and Mn(II) and distorted octahedral for Cu(II) complexes. Thermo gravimetric (TG) curves indicate the decomposition of complexes in four to five steps. The presence of coordinated water in metal complexes was confirmed by thermal, elemental analysis and IR data. Free ligand and its complexes were assayed in vitro for their antibacterial activity against gram positive and gram negative bacteria using chloramphenicol as a standard market-drug. Results: The reported complexes were synthesized through greener protocol that is grindstone method by mixing the ligand and metal salts in 2:1 molar ratio. Products were obtained in good yield with sharp melting point. Conclusion: Studies have indicated that such complexes can be prepared by environment friendly approach which requires less time, simple workup for isolation and purification with good yield. The [Ni(pmpt)2(H2O)2] complex showed excellent antibacterial activity while other reported metal complexes showed weak antibacterial activity.

L, where L is acetophenonebenzoylhydrazone (Abh), acetophenoneisonicotinoylhydrazone (Ainh), acetophenonesalicyloylhydrazone (Ash), acetophenoneanthraniloylhydrazone (Aah), p- hydroxyacetophenonebenzoylhydrazone (Phabh), p- hydroxyacetophenoneisonicotinoylhydrazone (Phainh), p- hydroxyacetophenonesalicyloylhydrazone (Phash), and p- hydroxyacetophenoneanthraniloylhydrazone (Phaah) were synthesized and characterized by elemental analyses, molar conductance, magnetic moments, electronic and IR spectra, and X-ray diffraction studies. The complexes are insoluble in common organic solvents and are non-electrolytes. These complexes are coordinated through the >C=O and >C=N groups of the hydrazone ligands. The magnetic moments and electronic spectra suggest a spin-free octahedral geometry around Co(II). The X-ray diffraction parameters (a, b, c) for Co[Cu(SCN)2]2 ? Ainh and Co[Cu(SCN)2] 2 ? Phabh correspond to orthorhombic and tetragonal crystal lattices, respectively. The complexes show a fair antifungal and antibacterial activity against a number of fungi and bacteria. The activity increases with increasing concentration of the compounds.
