Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. Product Details of 1111-67-7. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.

The coordination polymers 2?[(CuCN)2(mu-2 Mepyz)], 3?[CuCN(mu-2 Mepyz)] and 3?[CuCN(mu-4 Mepym)] (1-3) (2 Mepyz = 2-methylpyrazine; 4 Mepym = 4-methylpyrimidine) may be prepared by self-assembly in acetonitrile solution at 100 C (1, 3) or without solvent at 20 C (2). All three contain 1?[CuCN] chains that are bridged by the bidentate aromatic ligands into sheets in 1 and 3 D frameworks in 2 and 3. Reaction of CuSCN with these heterocyclic diazines at 100 C leads to formation of the lamellar coordination polymers 2?[(CuSCN)(mu-2 Mepyz)] (4) and 2?[CuSCN · (4 Mepym-kappaN1)] (5), which contain respectively 1?[CuSCN] chains and trans-trans fused 2?[CuSCN] sheets as substructures. The presence of an asymmetric substitution pattern in 2 Mepyz and 4 Mepym induces the adoption of a chiral structure by 2 and 5 (space groups P212121 and P1).

A new type of neutral heterometallic SbIII-CuI thiolate coordination polymer has been synthesized under solvothermal conditions by using antimony(III) thiolates as metalloligands and CuSCN as the source of the second metal ion. Reaction of [Sb(edt)Cl] (1) (edt = ethane-1,2-dithiolate) with 1 equivalent of CuSCN affords [{Sb2(edt) 2(mu3-S)CuCl(CuSCN)}n] (2), which features a 2D layer consisted of -CuSCNCuSCN-chains and {Sb2(edt) 2(mu3-S)CuCl} units. During the reaction, 1 was converted into a sulfur-bridged dimer Sb(edt)2S, which behaves simultaneously as a bridging and chelating ligand through all of its sulfur atoms to connect four Cu+ ions in the framework structure of 2. Replacement of Cl- in 1 with pymt-gives a new antimony(III) thiolate formulated as [Sb(edt)-(pymt)] (3) (pymt = 2-pyrimidinethiol), which was further treated with CuSCN to afford coordination polymers [{[Sb(edt)(pymt)] 2(CuSCN)3}n] (4) and [{[Sb(edt)(pymt)]-(CuSCN) 2}n] (5). In the assemblies of 4 and 5, the structure of 3 remains intact and the whole compound serves as a multidentate ligand through Sedt and Npymt atoms to Cu+ ions. Complex 4 also contains -CuSCNCuSCN- chains, which are linked by tridentate {Sb(edt)(pymt)} fragments to form a 2D polymer. Complex 5 is a 3D architecture with {Sb(edt)(pymt)} units acting as bidentate bridging ligand to link the (CuSCN)n layers and {(CuSCN)2}n columns. Complexes 2-5 showed optical transitions with band gaps of 2.66 to 3.41 eV, and their optical properties were studied by DFT calculations. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.

The [Cu2(SCN) 4]n anion in compounds 1, 3 and 5 adopts an infinite two-dimensional polypseudorotaxane architecture and proved effectively that the stoppers at the end can enhance the polyrotaxane formation in the crystalline state, whereas the anion moieties in compounds 2 and 6 exhibit one-dimensional linear architectures, suggesting dethreading from envelopes once solidifying from solution phase. Compound 4 was found to be a two-dimensional coordination polymer with the organic ligand carrying a single charge. The side chain template effect of substituted group, UV-Vis diffuse reflectance spectra in the solid state and TGA properties of the six complexes are investigated.

In this paper, a cross-linked poly(9-vinylcarbazole) (PVK):phosphomolybdic acid (PMA) layer is used as the hole transport layer in perovskite light-emitting devices, and the morphology, crystal structure, and photophysical properties of perovskite films on the PVK:PMA layer are studied. The addition of PMA into the PVK layer improves the perovskite morphology integrity and promotes hole transport. As a result, perovskite light-emitting devices using a PVK:PMA hole transport layer exhibit an improved maximum luminous efficiency of 22.1 cd A-1 and power efficiency of 18.2 lm W-1 when compared with those of the counterparts with a PVK hole transport layer. Efficient perovskite light-emitting devices can be accessed by using various antisolvents due to the good solvent resistance of PVK:PMA networks. Moreover, the luminous efficiencies of perovskite light-emitting devices with a PVK:PMA hole transport layer are almost invariant irrespective of the presence of a hole injection layer, illustrating wide applicability of the PVK:PMA hole transport layer in perovskite light-emitting devices.

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).

Molecular surfactants are widely used to control low-dimensional morphologies, including 2D nanomaterials in colloidal chemical synthesis, but it is still highly challenging to accurately control single-layer growth for 2D materials. A scalable stacking-hinderable strategy to not only enable exclusive single-layer growth mode for transition metal dichalcogenides (TMDs) selectively sandwiched by surfactant molecules but also retain sandwiched single-layer TMDs’ photoredox activities is developed. The single-layer growth mechanism is well explained by theoretical calculation. Three types of single-layer TMDs, including MoS2, WS2, and ReS2, are successfully synthesized and demonstrated in solar H2 fuel production from hydrogen-stored liquid carrier?methanol. Such H2 fuel production from single-layer MoS2 nanosheets is COx-free and reliably workable under room temperature and normal pressure with the generation rate reaching ?617 mumole g?1 h?1 and excellent photoredox endurability. This strategy opens up the feasible avenue to develop methanol-storable solar H2 fuel with facile chemical rebonding actualized by 2D single-layer photocatalysts.

Preparation of epitaxial YBa2Cu3O7 (YBCO) films on cerium oxide-buffered sapphire (r-cut alpha-Al2O3) substrates by an excimer-laser-assisted metalorganic deposition (ELAMOD) is reported. The ELAMOD process has been developed to bring about the advantage of shorter heating time than that in the conventional metalorganic deposition; the coated films are irradiated by an excimer laser beam before firing. We initiated the ELAMOD-YBCO process using a homogenized 8-mm-square laser beam which irradiates the coated surface in a fixed substrate mode. In order to extend the process applicable to large-area films, a scan irradiation mode was employed and a high critical-current density over 6 MA/cm2 has been observed. In the process, an appropriate choice of laser energy is difficult but crucial to obtain YBCO films with high superconducting properties. Then, laser irradiation from backside of the substrate was examined and proved to be beneficial to extend the experimental window of the laser energy. Moreover, a newly developed ELAMOD process using a 90-mm-wide line-beam is also reported which has a potential ability for large-area applications.
