Effect of surface treatment of the support on co oxidation over carbon-supported Wacker-type catalysts

The impact of surface treatment of the support on the oxidation of CO over carbon-supported Wacker-type catalyts was studied. This study focused on the effect of the chemical properties of activated carbon on CO oxidation over supported PdCl2-CuCl2 and PdCl2-CuCl2-Cu(NO)32 catalyts. The surface of active carbon used to prepare supported Wacker-type catalysts was enriched with carboxylic acid and carbonyl groups by pretreating with HNO3 or adding Cu(NO3)2 as a supplementary copper precursor. These surface groups improved the hydrophilicity and facilitated the formation of an active copper phase (Cu2Cl(OH)3). The effects were stronger, particularly on the formation of Cu2Cl(OH)3, when Cu(NO3)2 was combined with CuCl2 as catalyst precursors. The acceleration of CO oxidation can be attributed to the formation of the active copper phase and the improved hydrophilicity.

Copper-Catalyzed Cross-Coupling of Silicon Pronucleophiles with Unactivated Alkyl Electrophiles Coupled with Radical Cyclization

A copper-catalyzed C(sp3)-Si cross-coupling of aliphatic C(sp3)-I electrophiles using a Si-B reagent as the silicon pronucleophile is reported. The reaction involves an alkyl radical intermediate that also engages in 5-exo-trig ring closures onto pendant alkenes prior to the terminating C(sp3)-Si bond formation. Several Ueno-Stork-type precursors cyclized with excellent diastereocontrol in good yields. The base-mediated release of the silicon nucleophile and the copper-catalyzed radical process are analyzed by quantum-chemical calculations, leading to a full mechanistic picture.

All-solution-processed high-performance quantum dot light emitting devices employing an inorganic thiocyanate as hole injection layer

We report here the all-solution-processed, high-efficiency quantum dot light emitting diode (QLED) employing inorganic copper (I) thiocyanate (CuSCN) as hole injection layer. In comparison with the widely used injection material of poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS), the hole injection into the QD layer is significantly improved, allowing low turn-on voltage, high luminance and efficiency. By optimizing the multilayer structure and synergistically balancing the carrier injection, the resulting QLEDs exhibit high performance with the maximum current efficiency of 52.4 cd/A and external quantum efficiency of 12.0% for green device, 17.0 cd/A and 16.2% for red device. These results indicate that CuSCN is a reliable hole transport materials for low-cost, high-efficiency QLED devices.

Synthesis of 1D {Cu6(mu3-SC3H 6N2)4(mu-SC3H6N 2)2(mu-I)2I4}n and 3D {Cu2(mu-SC3H6N2) 2(mu-SCN)2}n polymers with 1,3-imidazolidine-2-thione: Bond isomerism in polymers

The reaction of copper(I) iodide with 1, 3-imidazolidine-2-thione (SC 3H6N2) in a 1:2 molar ratio (M/L) has formed unusual 1D polymers, {Cu6(mu3-SC3H 6N2)4(mu-SC3H6N 2)2(mu-I)2I4}n (1) and {Cu6(mu3-SC3H6N2) 2(mu-SC3H6N2)4(mu-I) 4I2}n (1a). A similar reaction with copper(I) bromide has formed a polymer {Cu6(mu3-SC 3H6N2)2(mu-SC3H 6N2)4(mu-Br)4Br2} n (3a), similar to 1a, along with a dimer, {Cu2(mu- SC3H6N2)2(eta1-SC 3H6N2)2Br2} (3). Copper(I) chloride behaved differently, and only an unsymmetrical dimer, {Cu2(mu-SC3H6N2) (eta1-SC3H6N2)3Cl 2} (4), was formed. Finally, reactions of copper-(I) thiocyanate in 1:1 or 1:2 molar ratios yielded a 3D polymer, {Cu2(mu-SC 3H6N2)2(mu-SCN)2} n (2).

Synthesis, structural and spectroscopic study of polymeric copper(I) thiocyanato complexes [Cu(NCS)L](n) (L = methyl nicotinate and ethyl nicotinate) and [HL] [Cu(NCS)2] (HL = H-ethyl isonicotinate)

Three new copper(I) thiocyanato complexes [Cu(NCS)L](n) (L = methyl nicotinate 1, ethyl nicotinate 2), and [HL] [Cu(NCS)2] (HL = H-ethyl isonicotinate 3), have been prepared and characterized by spectroscopic and crystallographic methods. All three complexes display MLCT transitions in the visible region, as well as visible solid state emission spectra at room temperature. Their IR spectra are measured and discussed. In the structure of 1 each copper atom links two S atoms from two mu-S,S,N thiocyanato ligands and two nitrogen atoms from a pyridine nucleus and from a third mu-S,S,N thiocyanate group; the two S atoms bind another copper atom forming a Cu2S2 cyclic unit. The ladder propagates along the a axis of the unit cell. The structure of 2 features CuS2N2 coordination with approximate tetrahedral environment, mu-S,S,N bridging thiocyanate groups giving rise to corrugated layers at y = 1/4. Complex 3 consists of an N-protonated ethyl isonicotinate cation and a polymeric [Cu(NCS)2]- anion. Each trigonal planar copper atom in the anion is coordinated by two S atoms from a mu-S,N thiocyanate bridge and a terminal S-thiocyanate group, and the third site is occupied by the end nitrogen of a mu-S,N thiocyanate bridge. The terminal NCS group forms a hydrogen bond of the type N-H¡¤¡¤¡¤N with an N-H group of the [HL]+ cation. The planar ribbon which runs in the a direction is further stabilized by N-H¡¤¡¤¡¤O hydrogen bonds. (C) 2000 Elsevier Science Ltd.

Electrochemical self-assembly of CuSCN-DAST hybrid thin films

Abstract: Nanostructured inorganic?organic hybrid thin films of copper(I) thiocyanate (CuSCN) and 4-(N,N-dimethylamino)-4?-(N?-methyl)stilbazolium tosylate (DAST) were electrochemically self-assembled by adding DAST into methanolic bath containing Cu2+ and SCN? ions. Loading of the stilbazolium organic chromophore (DAS+) increased linearly on increasing DAST concentration, accompanied with changes of the film morphology, crystallographic orientation of CuSCN and transition from beta- to alpha-CuSCN. At low DAST concentrations, transport limited passive occlusion of DAS+ has been suggested with its diffusion coefficient of 1.25?¡Á?10?6 cm2?s?1 in methanol at 298?K, while the loading receives kinetic limitation by the surface chemical reaction to yield definitive hybrid structures, resulting in unique ?hair comb? shape beta-CuSCN-DAST and ?nano-platelets? shape alpha-CuSCN-DAST hybrid structures. Both the inorganic and organic components are interconnected and bi-continuous, as the loaded DAS+ could be totally extracted by dimethylacetamide to leave porous skeleton of crystalline CuSCN, making them highly interesting for device applications.

Progress in Materials Development for the Rapid Efficiency Advancement of Perovskite Solar Cells

The efficiency of perovskite solar cells (PSCs) has undergone rapid advancement due to great progress in materials development over the past decade and is under extensive study. Despite the significant challenges (e.g., recombination and hysteresis), both the single-junction and tandem cells have gradually approached the theoretical efficiency limit. Herein, an overview is given of how passivation and crystallization reduce recombination and thus improve the device performance; how the materials of dominant layers (hole transporting layer (HTL), electron transporting layer (ETL), and absorber layer) affect the quality and optoelectronic properties of single-junction PSCs; and how the materials development contributes to rapid efficiency enhancement of perovskite/Si tandem devices with monolithic and mechanically stacked configurations. The interface optimization, novel materials development, mixture strategy, and bandgap tuning are reviewed and analyzed. This is a review of the major factors determining efficiency, and how further improvements can be made on the performance of PSCs.
