Halo and Pseudohalo Cu(I)-Pyridinato Double Chains with Tunable Physical Properties

The properties recently reported on the Cu(I)-iodide pyrimidine nonporous 1D-coordination polymer [CuI(ANP)]n (ANP = 2-amino-5-nitropyridine) showing reversible physically and chemically driven electrical response have prompted us to carry a comparative study with the series of [CuX(ANP)]n (X = Cl (1), X = Br (2), X = CN (4), and X = SCN (5)) in order to understand the potential influence of the halide and pseudohalide bridging ligands on the physical properties and their electrical response to vapors of these materials. The structural characterization of the series shows a common feature, the presence of -X-Cu(ANP)-X- (X = Cl, Br, I, SCN) double chain structure. Complex [Cu(ANP)(CN)]n (4) presents a helical single chain. Additionally, the chains show supramolecular interlinked interactions via hydrogen bonding giving rise to the formation of extended networks. Their luminescent and electrical properties have been studied. The results obtained have been correlated with structural changes. Furthermore, the experimental and theoretical results have been compared using the density functional theory (DFT). The electrical response of the materials has been evaluated in the presence of vapors of diethyl ether, dimethyl methylphosphonate (DMMP), CH2Cl2, HAcO, MeOH, and EtOH, to build up simple prototype devices for gas detectors. Selectivity toward gases consisting of molecules with H-bonding donor or acceptor groups is clearly observed. This selective molecular recognition is likely due to the 2-amino-5-nitropyridine terminal ligand.

Influence of the counter anion and solvent in the structure of copper derivatives with the 2,3-bis(2-pyridyl)pyrazine ligand

Several compounds have been isolated from the reaction between different copper bis(acetylacetonato) derivatives and the potentially bridging ligand 2,3-bis(2-pyridyl)pyrazine (bppz). A compound of formula [Cu(tfacac) 2(bppz)] (1) is obtained when the substituted trifluoromethylacetylacetonato is used. The use of different anions and the unsubstituted acetylacetonato give rise to new derivatives of general formula [{Cu(acac))2(mu-bppz)2]X2 (X– BF4-, 2; PF6-, 3; BPh 4-, 4). In these compounds the bppz ligand is acting as a bridge by chelating one copper atom and bonding monodentate a second copper atom. The presence of anions with different coordination abilities introduces variations in the copper environment and geometry. When the non-coordinating tetraphenylborate is used different compounds depending on the nature of the solvent are obtained. The dimer 4 was isolated from a methanol/chloroform mixture, while in the absence of chloroform the monomeric compound of formula [Cu(acac)(bppz)(ROH)](BPh4)-ROH (ROH=MeOH, 5) was obtained. When ethanol was used instead of methanol the analogous derivative 6 (R=EtOH) was isolated. Both species show a mononuclear structure with the copper atom five-coordinated by the chelating acac and bppz ligands and one hydroxo group occupying the apical position. A similar environment for the copper appears in [Cu(tfacac)(bppz)(MeOH)](BPh4), 7, which shows a dimeric structure through hydrogen bonds interactions. The magnetic susceptibility data of the dimeric compounds show very weak antiferromagnetic interactions between the copper atoms, an expected fact since the bridging bppz ligand is not planar but the monodentate pyridine is more or less perpendicular to the other two aromatic rings, precluding the spin exchange via the it ligand electrons.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 13395-16-9, help many people in the next few years.Reference of 13395-16-9

Synthesis and structural characterization of five copper(I) complexes of[2,3-f]-pyrazino-[1,10]phenanthroline-2,3-dicarbonitrile and triphenylp hosphine

Five new copper(I) complexes containing PPh3 and C 16H6N6, [Cu(PPh3)(C 16H6N6)Cl]?H2O (1), [Cu(PPh3)(C16H6N6)Br]?CH 3CN (2),[Cu(PPh3)(C16H6N 6)I]? CH3CN (3), [Cu(PPh3)(C 16H6N6)(CN)]?0.5 CH2Cl 2 (4) and Cu(PPh3)(C16H6N 6)(SCN) (5) {PPh3 = triphenylphosphine, C 16H6N6 = [2,3-f]-pyrazino-[1,10] phenanthroline-2,3-dicarbonitrile} have been synthesized for the first time. These complexes are obtained by the reactions of CuX (X = Cl, Br, I, CN, SCN) with the bidentate ligand C16H6N6 and the monodentate ligand PPh3 in the molar ratio of 1:1:1 in the mixed solvent of CH2Cl2 and CH3CN(5 ml/5 ml). They are characterized by X-ray crystallography, luminescence, IR, 1H NMR and 31P NMR. In solid state the complexes 1-5 are mononuclear with similar structures, but in solution they have different structures according to their different 1H NMR signals. All the complexes exhibit intense luminescence in solid state at room temperature.

Solid state luminescence of copper(i) (pseudo)halide complexes with neocuproine and aminomethylphosphanes derived from morpholine and thiomorpholine

The copper(i) iodide or copper(i) isothiocyanate complexes with 2,9-dimethyl-1,10-phenanthroline (dmp) and two interesting aminomethylphosphanes: P(CH2N(CH2CH2) 2O)3 (1) and novel P(CH2N(CH2CH 2)2S)3 (2): CuI(dmp)P(CH2N(CH 2CH2)2O)3 (1I), which was presented in our previous papers, CuI(dmp)P(CH2N(CH2CH 2)2S)3 (2I), CuNCS(dmp)P(CH 2N(CH2CH2)2O)3 (1T) and CuNCS(dmp)P(CH2N(CH2CH2)2S) 3 (2T) are discussed in this work. The chemical structures of three new complexes were determined in solution by means of NMR spectroscopy and in solid state using X-ray measurements. For all presented complexes the coordination geometry about the Cu(i) centre is pseudo-tetrahedral showing the small flattening and large rocking distortions. All compounds crystallize as the discrete dimers bound by pi-stacking interactions between dmp rings, which strongly depend on the phosphane ligand. Investigated complexes exhibit orange photoluminescence in the solid state of highly diversified intensity, position of the luminescence band and the lifetimes. On the basis of TDDFT calculations, the CT bands observed in UV-Vis spectra are assigned to the two mixed transitions from the CuX (X = I or NCS) bond with a small admixture of the CuP bond to pi* orbitals of the dmp ligand: (MX,MPR3)LCT. However, emission bands can be interpreted to be of (MX)LCT type.

Reactions of a tungsten trisulfido complex of hydridotris(3,5- dimethylpyrazol-1-yl)borate (Tp*) [Et4N][Tp*WS 3] with CuX (X = Cl, NCS, or CN): Isolation, structures, and third-order NLO properties

Reactions of a tungsten trisulfido complex of hydridotris(3,5- dimethylpyrazol-1-yl)borate (Tp*) [Et4N][Tp*WS 3] (1) with 3 equiv of CuCl in CHCl3 afforded a tetranuclear anionic cluster [Et4N][Tp*W(mu3-S) 3(CuCl)3] (2), while that of 1 with 3 equiv of CuNCS in MeCN produced a decanuclear neutral cluster (major product) [Tp*W(mu3-S)3Cu3(mu-NCS) 3(CuMeCN)]2 (3) along with a binuclear anionic cluster (minor product) [Et4N][Tp*WO(mu-S)2(CuNCS)] (4). Solvothermal reactions of 1 with 3 equiv of CuCN in MeCN at 80C for 48 h followed by slowly cooling it to ambient temperature gave rise to a polymeric cluster [Tp*W(mu3-S)(mu-S)2Cu 2(MeCN)(mu-CN)]n (5). Compounds 2-5 were characterized by elemental analysis, IR, UV-vis, 1H NMR, and single-crystal X-ray crystallography. The cluster anion of 2 has a [Tp*WS3Cu 3] incomplete cube with one Cl atom coordinated at each Cu center. 3 is composed of an unprecedented centrosymmetric W2Cu8 cluster core in which each void of the two single incomplete cubane-like [Tp*W(mu3-S)3Cu3(mu-NCS)] + cations is partially filled with an extra [Cu(MeCN)(mu-NCS) 2]- anion via a pair of Cu-mu-NCS-Cu bridges. The cluster anion of 4 contains one WS2Cu core that is formed by an oxidized [Tp*WO-(mu-S)2] species and one CuNCS fragment. 5 consists of butterfly shaped [Tp*W(mu3-S)(mu-S) 2Cu2(MeCN)] fragments that are interconnected via cyanide bridges to form a 1D spiral chain extending along the c axis. The successful synthesis of 2-5 from 1 suggests that 1 may be an excellent synthon to the W/Cu/S clusters. In addition, the third-order nonlinear optical (NLO) properties of 1-3 in solution were also investigated by femtosecond degenerate four-wave mixing (DFWM) technique with a 80 fs pulse width at 800 nm. Although 2 was not detected to have NLO effects, 1 and 3 exhibited relatively good optical nonlinearities with the nonlinear refractive index n2 and the third-order nonlinear optical susceptibility chi(3) values being 0.79 × 10-13 and 0.38 × 10-14 esu (1) and 2.08 × 10-13 and 1.00 × 10-14 esu (3), respectively. The second-order hyperpolarizability gamma value for 3 (5.46 × 10-32 esu) is ca. 5 times larger than that of its precursor 1.

Wavelength dependent photochemical charge transfer at the Cu2O-BiVO4 particle interface-evidence for tandem excitation

The understanding of the photochemical charge transfer properties of powdered semiconductors is of relevance to artificial photosynthesis and the production of solar fuels. Here we use surface photovoltage spectroscopy to probe photoelectrochemical charge transfer between bismuth vanadate (BiVO4) and cuprous oxide (Cu2O) particles as a function of wavelength and film thickness. Optimized conditions produce a -2.10 V photovoltage under 2.5 eV (0.1 mW cm-2) illumination, which suggests the possibility of a water splitting system based on a BiVO4-Cu2O direct contact particle tandem.

Planar perovskite solar cells employing copper(I) thiocyanate/N,N?-di(1-naphthyl)-N,N?-diphenyl-(1,1?-biphenyl)-4,4?-diamine bilayer structure as hole transport layers

Organic hole transport materials, such as N 2,N 2,N 2?,N 2?,N 7,N 7,N 7?,N 7?-octakis(4-methoxyphenyl)-9,9?-spirobi[9H-fluorene]-2,2?,7,7?-tetramine (Spiro-OMeTAD), are commonly used as the hole transport materials in efficient perovskite solar cells, but the chemical synthetic procedure may increase the cost of the photovoltaic devices. On the other hand, inorganic hole transport materials, such as copper(I) thiocyanate (CuSCN) or copper(I) iodide (CuI), have potential for the manufacture of efficient and low-cost perovskite solar cells, but the performance of these devices is still imperfect. In this study, we demonstrate the use of an inorganic CuSCN and organic N,N?-di(1-naphthyl)-N,N?-diphenyl-(1,1?-biphenyl)-4,4?-diamine (NPB) hybrid bilayer as an alternative hole transport layer for planar CH3NH3PbI3 perovskite solar cells. The electronic behavior of the bilayer and the performance of the corresponding devices were discussed. As a result, the power conversion efficiency (PCE) for the best cells at AM1.5G illumination with a shadow mask was 12.3%.
