The infinite layer copper oxides denoted as ACuO2, where A stands for the alkaline earth metal such as strontium or calcium, have attracted much attention in relation to high-temperature (Tc) superconductivity. Superconductivities of these species are achieved by several chemical doping such as hole-doping (h-doping) and electron-doping (e-doping). In this study, we have performed hybrid-density functional theory calculations, which are available in the strongly correlated systems such as transition metal complexes, in order to examine the electronic states after one e-doping for the linear chain clusters such as CuOCu and Cu3O2. The electronic states have been clarified from view points of energy, spin and charge density populations, natural orbital analysis and the difference of density. As the hole-doped electronic states have already been examined for the same clusters by the same methods in our previous work, we discuss the differences of the changes of electronic states between h-doping and e-doping.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 1317-39-1

A copper-catalyzed aminoboration of bicyclic alkenes, including oxa- and azabenzonorbornadienes, has been developed. With this method, amine and boron moieties are simultaneously introduced at an olefin with exo selectivity. Subsequent stereospecific transformations of the boryl group can provide oxygen- and nitrogen-rich cyclic molecules with motifs that may be found in natural products or pharmaceutically active compounds. Moreover, a catalytic asymmetric variant of this transformation was realized by using a copper complex with a chiral bisphosphine ligand, namely (R,R)-Ph-BPE.

Reactions of CuX (X=CN, NCS) with bis(3,5-dimethylpyrazolyl)methane (dmpzm) gave rise to two new coordination polymers [CuX(dmpzm)]n (X=CN (2), NCS (3)). Compounds 2 and 3 were characterized by elemental analysis, IR spectra and X-ray crystallography. The molecular structure of 2 has a one-dimensional zigzag chain of [CuCN(dmpzm)] units while that of 3 consists of a one-dimensional single-strand spiral chain of [CuNCS(dmpzm)] units. The luminescence properties of CuX (X=I (1), CN (2), NCS (3)) adducts of dmpzm along with free dmpzm were also investigated.

Compounds 1, 3 and 4 consist of neutral tetranuclear entities in which the CuII ions are coordinated by the tridentate Schiff base ligands, forming a tetranuclear Cu4O4 cubane-like configuration. Compound 5 contains similar cubane-like tetranuclear entities which are further linked through the hydroxyl groups of the ligands thus forming dimers of cubanes. Compound 2 contains a neutral dinuclear entity in which the CuII ions are bridged through the Schiff base and the acetate ligands, comprising distorted Cu2O2 core. The Schiff base ligand adopts five different coordination modes and two deprotonation states in the structures of 1?5 acting simultaneously as chelating and bridging agent between the metal ions. The lattice structures of 1?5 exhibit interesting 3D networks based on hydrogen bonded metal clusters and they are studied with Hirshfeld Surface analysis methods.

Three novel metal complexes [(acac)2Cu2(NtBu)4S] (3), [Li(thf)4]2[I4Cd2(NtBu)4S] (4) and [(thf)2Li{(SiMe3)2N}Zn(NtBu)4S] (5) are prepared from the intended transmetalation of the dilithium complex of N,N?,N??,N???-tetrakis(tert-butyl)tetraimidosulfate [(thf)4Li2(NtBu)4S] (1). The two lithium cations are replaced by either the cationic (acac)Cu(ii) moiety, the neutral I2Cd(ii) residue or only a single lithium cation is substituted by the cationic (Me3Si)2NZn(ii) fragment. The complexes show two main results: first the S(NtBu)42- tetrahedron can serve as a ligand to transition metals from the soft Cu(ii) to the harder Zn(ii) at opposite sides and second the S-N bond distances vary only marginally in response to the various metals and the four distances constantly sum up to 6.38(2) A. Hence the electropositive sulfur atom responds by internal shift to the metal-polarized negative charge at the outside of the S(NR)42- tetrahedron. This journal is

The assembly of a new family of [(eta5-C5Me 5)MoS3Cu3]-supported supramolecular compounds from a preformed cluster [PPh4][(eta5-C 6Me5)MoS3(CuNCS)3]·DMF (1·DMF) with four multitopic ligands with different symmetries is described. Reactions of 1 with 1,2-bis(4-pyridyl)ethane (bpe) (Cs symmetry) or 1,4-pyrazine (1,4-pyz) (D2h symmetry) in aniline gave rise to two polymeric clusters {[{(eta5-C5Me 5)MoS3Cu3}2(NCS)3(mu- NCS)(bpe)3]·3aniline}n (2) and [(eta5- C5Me5)MoS3Cu3(1,4-pyz)(mu-NCS) 2]n (3). On the other hand, solid-state reactions of 1 with 2,4,6-tri(4-pyridyl)-1,3,5-triazine (tpt) (D3h symmetry) or 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphyrin (H2tpyp) (D 4h symmetry if 21H and 23H of the H2tpyp are omitted) at 100C for 12 h followed by extraction with aniline yielded another two polymeric clusters {[(eta5-C5Me5)MoS 3Cu3(tpt)(aniline)(NCS)2]·0. 75aniline·0.5H2O}n (4) and {[(eta5- C5Me5)MoS3Cu3(NCS)(mu-NCS)(H 2tpyp)0.4(Cu-tpyp)0.1] ·2aniline·2.5benzene}n (5). These compounds were characterized by elemental analysis, IR spectra, UV-vis spectra, 1H NMR, and X-ray analysis. Compound 2 consists of a 2D (6,3) network in which [(eta5-C5Me5)MoS3Cu3] cores serve both a T-shaped three-connecting node and an angular two-connecting node to interconnect other equivalent units through single bpe bridges, double bpe bridges, and mu-NCS bridges. Compound 3 has a 3D diamondlike framework in which each [(eta5-C5Me5)MoS 3Cu3] core, acting as a tetrahedral connecting node, links four other neighboring units by 1,4-pyz bridges and mu-NCS bridges. Compound 4 contains a honeycomb 2D (6,3)core(6,3)tpt network in which each cluster core, serving a trigonal-planar three-connecting node, links three pairs of equivalent cluster cores via three tpt lignads. Compound 5 has a rare scalelike 2D (4,62)core(42,6 2)ligand network in which each cluster core acts as a T-shaped three-connecting node to link with other equivalent ones through mu-NCS bridges and H2tpyp (or Cu-tpyp) ligands. The results showed that the formation of the four different multidimensional topological structures was evidently affected by the symmetry of the ligands used. In addition, the third-order nonlinear optical properties of 1-5 in aniline were also investigated by using Z-scan techniques at 532 nm.

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.

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.
