The electronic structures of Ni(II) and Cu(II) bis(acetylacetonates) and some of their gamma-substituted analogues (X = Cl, Me) are studied by photoelectron spectroscopy (PES). The vertical ionization energies of the compounds are determined, and the spectra are interpreted based on the trends of changes in the electronic structure and photoelectron spectra of acetylacetonates upon gamma-substitution. The suggested interpretation of the photoelectron spectra is confirmed by the quantum chemical INDO calculations of the electronic structure of the Cu(II) compounds.

Quantum dot sensitized solar cells (QDSSCs) are a promising photovoltaic technology due to their low cost and simplicity of fabrication. Most QDSSCs have an n-type configuration with electron injection from QDs into TiO2, which generally leads to unbalanced charge transport (slower hole transfer rate) limiting their efficiency and stability. We have previously demonstrated that p-type (inverted) QD sensitized cells have the potential to solve this problem. Here we show for the first time that electrodeposited CuSCN nanowires can be used as a p-type nanostructured electrode for p-QDSSCs. We demonstrate their efficient sensitization by heavy metal free CuInSxSe2-x quantum dots. Photophysical studies show efficient and fast hole injection from the excited QDs into the CuSCN nanowires. The transfer rate is strongly time dependent but the average rate of 2.5 × 109 s-1 is much faster than in previously studied sensitized systems based on NiO. Moreover, we have developed an original experiment allowing us to calculate independently the rates of charge injection and QD regeneration by the electrolyte and thus to determine which of these processes occurs first. The average QD regeneration rate (1.3 × 109 s-1) is in the same range as the hole injection rate, resulting in an overall balanced charge separation process. To reduce recombination in the sensitized systems and improve their stability, the CuSCN nanowires were coated with thin conformal layers of Al2O3 using atomic layer deposition (ALD) and fully characterized by XPS and EDX. We demonstrate that the alumina layer protects the surface of CuSCN nanowires, reduces charge recombination, and increases the overall charge transfer rate up to 1.5 times depending on the thickness of the deposited Al2O3 layer.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

This communication describes the crystal structures of CuI complexes and their topological analysis with an emphasis on the Laplacian of the electron density to investigate the characteristics of halogen bonding. To gain insight into the halogen bonds (XBs), we survey wavefunction and DFT methods. The different XBs, that is, Cl···Cl?, I···I?, Br···N3?, and I···SCN?, in the crystal packing of these compounds are categorized as a combination of a region of charge depletion and a region of charge concentration in the valence-shell charge concentration or hole?lump interactions. The full quantum potential based lump?hole concept is more useful than the sigma-hole concept, in which the electrostatic portion of the potential is merely considered. Such a view of halogen bonding can rationalize the geometry around the XBs. The noncovalent interaction reduced density gradient (NCI-RDG) approach was applied to the real-space visualization and quantitative investigation of the XBs as well.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about name: 6-Chloropyridazine-3-carboxamide!, Synthetic Route of 1111-67-7

The ability to tune the electronic properties of soluble wide bandgap semiconductors is crucial for their successful implementation as carrier-selective interlayers in large area opto/electronics. Herein the simple, economical, and effective p-doping of one of the most promising transparent semiconductors, copper(I) thiocyanate (CuSCN), using C60F48 is reported. Theoretical calculations combined with experimental measurements are used to elucidate the electronic band structure and density of states of the constituent materials and their blends. Obtained results reveal that although the bandgap (3.85 eV) and valence band maximum (?5.4 eV) of CuSCN remain unaffected, its Fermi energy shifts toward the valence band edge upon C60F48 addition?an observation consistent with p-type doping. Transistor measurements confirm the p-doping effect while revealing a tenfold increase in the channel’s hole mobility (up to 0.18 cm2 V?1 s?1), accompanied by a dramatic improvement in the transistor’s bias-stress stability. Application of CuSCN:C60F48 as the hole-transport layer (HTL) in organic photovoltaics yields devices with higher power conversion efficiency, improved fill factor, higher shunt resistance, and lower series resistance and dark current, as compared to control devices based on pristine CuSCN or commercially available HTLs.

Low temperature processed Perovskite solar cells (PSCs) are popular due to their potential for scalable production. In this work, we report reduced Graphene Oxide (r-GO)/copper (I) thiocyanate (CuSCN) as an efficient bilayer hole transport layer (HTL) for low temperature processed inverted planar PSCs. We have systematically optimized the thickness of CuSCN interlayer at the r-GO/MAPbI3 interface resulting in bilayer HTL structure to enhance the stability and photovoltaic performance of low temperature processed r-GO HTL based PSCs with a standard surface area of 1.02 cm2. With matched valence band energy level, the r-GO/CuSCN bilayer HTL based PSCs showed high power conversion efficiency of 14.28%, thanks to the improved open circuit voltage (VOC) compared to the only r-GO based PSC. Moreover, enhanced stability has been observed for the r-GO/CuSCN based PSCs which retained over 90% of its initial efficiency after 100 h light soaking measured under continuous AM 1.5 sun illumination.

Copper thiocyanate (CuSCN) has recently received considerable attention because of its high hole mobility and applications in solar cells [Science 358(2017)768]. In this work, by performing state-of-the-art theoretical calculations, for the first time we find that the thermal conductivities of both alpha- and beta-CuSCN are ultralow with the values of 1.2 and 2.4 W/mK at room temperature, respectively. Based on detailed analyses of the phonon dispersion, Grueneisen parameters, three phonon scattering rates and atomic displacement parameters, we further demonstrate that the underlying reasons for the ultralow thermal conductivities are due to the avoided crossing between the longitudinal acoustic (LA) phonons and the low-lying optical branches as well as the weak bonding and strong anharmonicity. The low lattice thermal conductivities lead to high ZT values of 1.7 and 2.1 at 800 K for alpha- and beta-CuSCN, respectively. In addition, both materials exhibit large negative thermal expansion (NTE) coefficients originated from the transverse vibrations in Cu?N?C?S chains. These features endow CuSCN with the potential for thermal barrier coating and thermal devices going beyond the reported photovoltaic applications.

Thiolate self-assembly on gold has proven to be a valuable technique for assembling monolayers on a wide variety of substrates. However, the oxidative instability of the thiols, especially aromatic thiols and alpha,omega-dithiols, presents several difficulties. Shown here is that thiocyanates, easily synthesized stable thiol derivatives, can be directly assembled on gold surfaces with no auxiliary reagents required. Assembly is complete in 24 h and leaves a similar gold thiolate structure as seen in typical thiol self-assembled monolayers. Copyright

These nine complexes were synthesized by the reactions of copper salts, diimine ligands and various of P-donor ligands through one-pot method. Single crystal X-ray diffraction reveals that complex 9 is of a simple mono-nuclear structure while complexes 6 and 7 are of dimer structures. For complex 8, hydrogen bonds and C?H?pi interactions lead to the formation of a 1D infinite chain structure. Interestingly, complexes 1?5 show novel 2D or 3D network structures through C?H?pi interactions. In addition, complexes 1?3 and 6?9 exhibit interesting fluorescence in the solid state at room temperature.
