Syntheses and crystal structures of

Through the reaction of CuSCN with AsPh-(SiMe3)2 in the presence of tertiary phosphines the compounds [Cu4(As4Ph4)2(PRR? 2)4] (1-3) (1: R = R? = nPr, 2: R = R? = Et; 3: R = Me, R? = nPr) and [Cu14(AsPh)6(SCN)2-(PEt2Ph) 8] (4) can be synthesised. Using CuCl instead of CuSCN results to the cluster complexes [Cu14(AsPh)6Cl2(PRR?2) 8] (5-6) (5: R = R? = Et; 6: R = Me, R? = nPr), [Cu12(AsPh)6(PPh3)6] (7) and [Cu10(AsPh)4Cl2-(PMe3)8] (8).

Enabling High-Efficiency Organic Light-Emitting Diode with Trifunctional Solution-Processable Copper(I) Thiocyanate

We report on a low-Temperature solution processed trifunctional inorganic p-Type semiconductor, copper(I) thiocyanate (CuSCN), as a hole injection/transporting and electron-blocking layer for high-efficiency organic light-emitting diodes (OLEDs). The electroluminescence (EL) characteristics of CuSCN and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) based devices were studied with the structure of 4,4?-bis(N-carbazolyl)-1,1?-biphenyl as the host, bis[2-(2-pyridinyl-N)phenyl-C](acetylacetonato)iridium(III) [(ppy)2Ir(acac)] as the green emitter, 2,2?,2?-(1,3,5-benzinetriyl)-Tris(1-phenyl-1H-benzimidazole) as the electron transporting layer, and lithium fluoride/aluminum as the cathode electrode. The power efficacies for the CuSCN based devices are found to be 51.7 and 40.3 lm/W at 100 and 1000 cd/m2, respectively, which are 13 and 60% higher than the PEDOT:PSS based counterparts. These are the highest power efficacies ever reported for this particular device architecture. The superior EL characteristics may be explained by its unique electronic properties. We believe that the high lowest unoccupied molecular orbital (a’1.8 eV) and deep highest occupied molecular orbital (a’5.5 eV) of CuSCN assist to confine the electron injected into the emission layer and facilitate the injection of hole, likewise enhancing recombination. The present study will serve to enable highly efficient white OLEDs for general lighting purposes.

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

Solution-based synthesis and characterization of Cu2ZnSnS 4 nanocrystals

(Figure Presented) Recent advances have been made in thin-film solar cells using CdTe and CuIn1-xGaxSe2 (CIGS) nanoparticles, which have achieved impressive efficiencies. Despite these efficiencies, CdTe and CIGS are not amenable to large-scale production because of the cost and scarcity of Te, In, and Ga. Cu2ZnSnS4 (CZTS), however, is an emerging solar cell material that contains only earth-abundant elements and has a near-optimal direct band gap of 1.45-1.65 eV and a large absorption coefficient. Here we report the direct synthesis of CZTS nanocrystals using the hotinjection method. In-depth characterization indicated that pure stoichiometric CZTS nanocrystals with an average particle size of 12.8 ¡À 1.8 nm were formed. Optical measurements showed a band gap of 1.5 eV, which is optimal for a single-junction solar device.

The reaction of copper(I) salts CuX (X = Cl, Br, I, CN, SCN), [Cu(CH3CN)4]PF6 with 1-diphenylphosphino-1?-di-tert-butylphosphinoferrocene (dppdtbpf) in 1:1 M ratio in DCM-MeOH (50:50 V/V) at room temperature afforded mono and binuclear compounds having formula [Cu2(mu-Cl)2(kappa2-P,P-dppdtbpf)2] (1), [Cu2(mu-Br)2(kappa2-P,P-dppdtbpf)2] (2) [Cu2(mu-I)2(kappa2-P,P-dppdtbpf)2] (3), [Cu2(mu-CN)2(kappa2-P,P-dppdtbpf)2] (4), [Cu2(mu2-SCN)2(kappa2-P,P-dppdtbpf)2] (5), and [Cu(kappa2-P,P-dppdtbpf)(CH3CN)2]PF6 (6). Reacting palladium(II) complex [Pd(C6H5CN)2Cl2] with dppdtbpf gave mononuclear compound [Pd(kappa2-P,P-dppdtbpf)Cl2] (7). The reaction of dppdtbpf with sulfur powder under reflux in chloroform afforded a ferrocene diphosphine disulfide dppSdtbpSf (8). All of the synthesized compounds were characterized by elemental analyses, IR, 1H and 31P NMR, ESI-MS and electronic absorption spectroscopy. Molecular structures for the compounds 5, 6, 7 and 8 were determined crystallographically. Compound 5 exists as centrosymmetric dimer in which the two copper atoms are bonded to two dppdtbpf ligands and two bridging thiocyanate groups in mu2-manner. In cationic compound 6, the copper atom is coordinated to one dppdtbpf ligand in kappa2-manner and two acetonitrile molecules, whereas in 7, the palladium(II) adopted cis square-planar geometry by coordinating to one dppdtbpf ligand in kappa2-manner and two chlorine atoms. Compound 8 revealed a sandwiched structure with both phosphine groups sulfurized. The electrochemical properties of 1-6 were studied by cyclic voltammetry. Compounds 1-6 exhibited moderately weak to strong luminescence properties, however compounds 7 and 8 are non-emissive in the solution state.

Hydrothermal reaction of CuCN, K3[Fe(CN)6] with 4-(6-amino-2-pyridyl)-1,2,4-triazole (apt) afforded a coordination polymer [Cu7(CN)7(apt)2]n (1), while solvothermal reaction of CuSCN with apt in acetonitrile afforded a coordination polymer [Cu2(SCN)2(apt)]n (2). Complex 1 shows two-dimensional polymeric network with large hexagonal channels constructing by CuCN chains and tridentate apt ligands. Complex 2 shows two-dimensional polymeric framework assembled by ladder-like [Cu(SCN)]n chains and bidentate apt ligands, in which thiocyanate acts as a tridentate bridging ligand. Both polymers are thermal stable and strong fluorescent in the solid state.
