Synthesis of Ba2YCu3O7-delta Superconductor through Organometallic Route

The chemical synthesis of a high-Tc Ba2YCu3O7-delta superconductor was investigated through the organometallic route, using Ba metal, Y(OPri)3, and Cu-alkoxides or Cu-acetylacetonate as starting materials.Chemically homogeneous submicron powders of single phase Ba2YCu3O7-delta were successfully prepared at 750 deg C by controlled partial hydrolysis metal alkoxides.The utilization of ozone for favorable decomposition of Ba2YCu3O7-delta precursors was found to have a remarkable effect on suppressing the formation of Ba CO3 and lowering the formation temperature of Ba2YCu3O7-delta to about 650 deg C.The single phase Ba2YCu3O7-delta ceramics exhibited superconductivity at approximately 83 K (Tc end).

Synthesis and crystal structure of tetra- and hexanuclear uranium(IV) complexes with hexadentate compartmental Schiff-base ligands

Treatment of UCl4 with the hexadentate Schiff bases H 2L? in thf gave the expected [UL?Cl2(thf)] complexes [H2L? = N,N?-bis(3-methoxysalicylidene)-R and R = 2,2-dimethyl-1,3-propanediamine (i = 1), R = 1,3-propanediamine (i = 2), R = 2-amino-benzylamine (i = 3), R = 2-methyl-1,2-propanediamine (i = 4), R = 1,2-phenylenediamine (i = 5)]. The crystal structure of (UL4Cl 2(thf)] (4) shows the metal in a quite perfect pentagonal bipyramidal configuration, with the two Cl atoms in apical positions. Reaction of UCl 4 with H4L? in pyridine did not afford the mononuclear products [U(H2L?)Cl2(py)x] but gave instead polynuclear complexes [H4L? = N,N?-bis(3-hydroxysalicylidene)-R and R = 1,3-propanediamine (i = 6), R = 2-amino-benzylamine (i = 7) or R = 2-methyl-1,2-propanediamine (i = 8)]. In the presence of H4L6 and H4L7 in pyridine, UCl4 was transformed in a serendipitous and reproducible manner into the tetranuclear U(IV) complexes [Hpy]2[U 4(L6)2(H2L6) 2Cl6] (6a) and [Hpy]2[U4(L 7)2(H2L7)2Cl 6][U4(L7)2(H2L 7)2 Cl4(py)2] (7), respectively. Treatment of UCl4 with [Zn(H2L6)] led to the formation of the neutral compound [U4(L6) 2(H2L6)2Cl4(py) 2] (6b). The hexanuclear complex [Hpy]2[U 6(L8)4Cl10(py)4] (8) was obtained by reaction of UCl4 and H4L8. The centrosymmetric crystal structures of 6a¡¤2HpyCl¡¤2py, 6b¡¤6py, 7¡¤16py and 8¡¤6py illustrate the potential of Schiff bases as associating ligands for the design of polynuclear assemblies.

The use of copper-based antifoulings on aluminium ship hulls

Copper, most commonly in the form of copper oxide, is used in the majority of marine antifoulings globally, but some paint companies do not allow their copper oxide based antifoulings to be used on aluminium hulls. This is because aluminium is more anodic in the electrochemical series than copper and if the two are in direct connect in sea water, the aluminium will corrode away. This galvanic reaction only occurs if copper metal is in direct contact with aluminium, and since modern copper oxide based antifoulings contain virtually no metallic copper there appears to be no valid reason for the ultra-cautious approach regarding the use of copper oxide based antifoulings on aluminium hulls. A number of different copper-based commercial antifoulings were applied on suitably prepared Marine-grade aluminium panels, along with an un-coated control panel. The panels were immersed in seawater. Furthermore a laboratory experiment was also undertaken where coated aluminium panels were submerged in a salt water solution as a controlled experiment. All the samples were then analysed using electron microscopy. Copper leaching out of copper oxide based antifoulings had no effect on the corrosion of Marine-grade aluminium.

Syntheses and crystal structures of novel chalcogenido-bridged niobium copper clusters

In the presence of tertiary phosphines, the reaction of NbCl5 and Copper(I) salts with Se(SiMe3)2 (E = S, Se) affords the new chalcogenido-bridged niobium-copper cluster compounds x 1[NbCu3Se4(PiPr2Me) 3] (1) and [NbCu4Se4Cl (PPh3) 4] (2). Using E(R)SiMe3 (E = S, Se, R = Ph, nPr) instead of the bisilylated selenium species leads to the compounds [NbCu2(SPh)6(PMe3)2] (3), [NbCu2(SPh)6(PnPr3)2] (4), [NbCu2(SePh)6(PMe3)2] (5), [NbCu2(SePh)6(PnPr3)2] (6), [NbCu2(SePh)6(PiPr3) 2] (7), [NbCu2(SePh)6(PtBu 3)2] (8), [NbCu2(SePh)6(P iPr2Me)2] (9), [NbCu2(SePh) 6(PPhEt2)2] (10), [Nb2Cu 2(SnPr)8(PnPr3) 2Cl2] (11) and [Nb2Cu6(S nPr)12(PiPr3)2Cl 4]¡¤2 CH3CN (12¡¤1 CH3CN). By reacting CuI salts and NbCl5 with the monosilylated selenides Se(tBu)SiMe3 and Se(iPr)SiMe 3 which have a weak Se-C bond the products [Nb2Cu 6Se6(PiPr3)6Cl 4] (13), [Nb2Cu4Se2(Se iPr)6-(PnPr3)4Cl 2] (14) and [Nb2Cu6Se2(Se iPr)10(PEt2Me)2Cl 2]¡¤DME (15) are formed which contain selenide as well as alkylselenolate ligands. The molecular structures of all of these new compounds were determined by single crystal X-ray diffraction measurements.

Bright green-to-yellow emitting Cu(i) complexes based on bis(2-pyridyl)phosphine oxides: Synthesis, structure and effective thermally activated-delayed fluorescence

A family of brightly luminescent dinuclear complexes of [Cu(mu2-X)(N^N)]2 type (X = I or SCN) has been synthesized in 76-90% yields by the reaction of bis(2-pyridyl)phosphine oxides (N^N) with the corresponding Cu(i) salts. The X-ray diffraction study reveals that the Cu2I2 core of the [Cu(mu2-I)(N^N)]2 complexes has either a butterfly- or rhomboid-shaped structure, while the eighth-membered [Cu(SCNNCS)Cu] ring in the [Cu2(SCN)2(N^N)]2 complexes is nearly planar. In the solid state, these compounds exhibit a strong green-to-yellow emission (lambdaemmax = 536-592 nm) with high PLQYs (up to 63%) and short lifetimes (1.9-10.0 mus). The combined photophysical and DFT study indicates that the ambient-temperature emission of the complexes obtained can be assigned to the thermally activated-delayed fluorescence (TADF) from the 1(M + X)LCT excited state, while at 77 K, phosphorescence from the 3(M + X)LCT state is likely observed.

Iron Complexes of N-Substituted Thiosalicylideneimines. Part 1. Synthesis and Reactions with Oxygen and Carbon Monoxide

Iron(II) complexes with N-substituted bidentate and tetradentate thiosalicylideneimines can be prepared by the reaction of bis(thiosalicylaldehydato)iron(II) with appropriate primary amines.The bidentate compounds show S = 2 spin states while a number of the tetradentate compounds have the unusual S = 1 state.The tetradentate complexes react with CO to form monocarbonyl complexes and with O2 to form FeIII mu-oxo-bridged derivatives.Some evidence is presented to support the preliminary formation at low temperatures of a dinuclear iron(III) peroxo-species as the precursor of the mu-oxo-compounds.Several spin-paired FeIII compounds containing SN2-bonded tridentate ligands are also reported.

Copper(I) Thiocyanate (CuSCN) Hole-Transport Layers Processed from Aqueous Precursor Solutions and Their Application in Thin-Film Transistors and Highly Efficient Organic and Organometal Halide Perovskite Solar Cells

This study reports the development of copper(I) thiocyanate (CuSCN) hole-transport layers (HTLs) processed from aqueous ammonia as a novel alternative to conventional n-alkyl sulfide solvents. Wide bandgap (3.4?3.9 eV) and ultrathin (3?5 nm) layers of CuSCN are formed when the aqueous CuSCN?ammine complex solution is spin-cast in air and annealed at 100 C. X-ray photoelectron spectroscopy confirms the high compositional purity of the formed CuSCN layers, while the high-resolution valence band spectra agree with first-principles calculations. Study of the hole-transport properties using field-effect transistor measurements reveals that the aqueous-processed CuSCN layers exhibit a fivefold higher hole mobility than films processed from diethyl sulfide solutions with the maximum values approaching 0.1 cm2 V?1 s?1. A further interesting characteristic is the low surface roughness of the resulting CuSCN layers, which in the case of solar cells helps to planarize the indium tin oxide anode. Organic bulk heterojunction and planar organometal halide perovskite solar cells based on aqueous-processed CuSCN HTLs yield power conversion efficiency of 10.7% and 17.5%, respectively. Importantly, aqueous-processed CuSCN-based cells consistently outperform devices based on poly(3,4-ethylenedioxythiophene) polystyrene sulfonate HTLs. This is the first report on CuSCN films and devices processed via an aqueous-based synthetic route that is compatible with high-throughput manufacturing and paves the way for further developments.
