Synthetic Route of 1111-67-7, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. In an article, authors is Chavhan, Sudam D., once mentioned the application of Synthetic Route of 1111-67-7, Name is Cuprous thiocyanate,molecular formula is CCuNS, is a conventional compound.

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.

We present an energy band model and a method for filling p-type CuSCN in n-type porous TiO2 film. The energy band model is based on the interface energy levels between TiO2/CuSCN heterojunction and the aqueous electrolyte. The whole deposition process is divided into three stages: the uniform nucleation on the internal surface at positive potential, the crystal growth with the cathodic potential shifting negatively and the thermal activated growth at constant potential. This was demonstrated by the electrochemical experiment combining the hydrothermal process. It was found that the obtained TiO2/CuSCN heterojunction exhibited good rectification characteristics, indicating that an intimate electrical contact was formed between the large internal surface of TiO2 film and CuSCN. This novel hydrothermal-electrochemical method may be valuable for fabricating extremely thin absorber (eta)-solar cells and other semiconductor devices.

In the presence of CuX (X = I, Br, SCN) and electrophilic fluoride reagents, a variety of N-(p-methoxyaryl)propiolamides and 4-methoxyphenyl 3-phenylpropiolate were cyclized to selectively afford the corresponding spiro[4.5]decenones in moderate to good yields. It is noteworthy that two azaquaternary tricyclic products were synthesized through a two-step pathway involving an electrophilic ipso-cyclization and then an intramolecular Heck reaction.

Reaction of copper(I) thiocyanate and triphenylphosphane with the bidentate Schiff base N,N?-bis(trans-2-nitrocinnamaldehyde)ethylenediamine {Nca2en, (1); systematic name (1E,1?E,2E,2?E)-N,N?-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]}, C20H18N4O4, in a 1:1:1 molar ratio in acetonitrile resulted in the formation of the complex {(1E,1?E,2E,2?E)-N,N?-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]-kappa2 N,N?}(thiocyanato-kappaN)(triphenylphosphane-kappaP)copper(I)], [Cu(NCS)(C20H18N4O4)(C18H15P)] or [Cu(NCS)(Nca2en)(PPh3)], (2). The Schiff base and copper(I) complex have been characterized by elemental analyses, IR, electronic and 1H NMR spectroscopy, and X-ray crystallography [from synchrotron data for (1)]. The molecule of (1) lies on a crystallographic inversion centre, with a trans conformation for the ethylenediamine unit, and displays significant twists from coplanarity of its nitro group, aromatic ring, conjugated chain and especially ethylenediamine segments. It acts as a bidentate ligand coordinating via the imine N atoms to the CuI atom in complex (2), in which the ethylenediamine unit necessarily adopts a somewhat flattened gauche conformation, resulting in a rather bowed shape overall for the ligand. The NCS- ligand is coordinated through its N atom. The geometry around the CuI atom is distorted tetrahedral, with a small N-Cu-N bite angle of 81.56(12) and an enlarged opposite angle of 117.29(9) for SCN-Cu-P. Comparisons are made with the analogous Schiff base having no nitro substituents and with metal complexes of both ligands.

Complexes containing di(2-pyridyl) ketone (dpk) as a bi- (N,N) and tridentate (N,N,O) ligand have been synthesised1,2 and characterized by spectral and structural studies. Products 1 and 2 are polymorphs of the polymeric copper(I) complex [Cu(dpk)(NCS)]n containing dpk with thiocyanate anions which bridge to form a one-dimensional continuous polymer chain. The novel dinuclear copper(II) complex [Cu2(dpkA·acetone) 2(NCS)2] (3) was formed when 1 and 2 were allowed to stand in the supernatant. In this instance it appears that a transition-metal- promoted aldol condensation has occurred between the solvent acetone and the ketone carbonyl of dpk to produce the novel ligand, dpkA·acetone. Product 3 contains two five-coordinate copper(II) ions, both with trigonal bipyramidal coordination, bridged through deprotonated hydroxy groups on each dpkA·acetone. A chemical rationalisation for the formation of 3 is proposed. The dinuclear copper(I) complex [Cu2(dpk)2I 2] (4) is also reported, which contains two four-coordinate copper(I) ions that are bridged together through iodide ions.

Four cubane-like CU4I4 units are assembled around an iodine atom to form the giant, mixed-valent CuIICuI 15I17 cluster. The CuIICuI 15I17 cluster and a bipyrazole linker form a 3D open framework with paramagnetic and thermochromic properties. This paper also touches on the resemblance of this cluster to the self-similar object of a Sierpinski tetrahedron.

New late-stage phosphorothiolation methods are disclosed that allow the efficient transfer of SP(O)(OR)2 groups to diversely functionalized substrates using nucleophilic and electrophilic reagents. The nucleophilic reagent, tetramethylammonium O,O-dimethyl phosphorothioate, was synthesized in near-quantitative yield from Me3SiP(O)(OMe)2, elemental sulfur and Me4NF. Its umpolung with N-bromophthalimide provided the electrophilic reagent, O,O-dimethyl-S-(N-phthalimido)phosphorothioate. Complementary methods based on these reagents enable the phosphorothiolation of diversely functionalized alkyl halides, arenediazonium salts, arylboronic acids and electron-rich arenes in good yields under mild conditions.

Syntheses and infrared spectroscopic studies are reported for two different polymorphs of copper(I) thiocyanate and for adducts of copper(I) thiocyanate with thiourea (‘tu’) and ethylenethiourea (‘etu’ = imidazolidine-2-thione; (CH2NH)2CS)). These include the previously reported complex CuSCN/etu (1: 2), which has a trigonal monomeric structure, and CuSCN/etu (1: 1), which has a three-dimensional polymeric structure. A mechanochemical/infrared study of the CuSCN: tu (1: 2) system showed that no 1: 2 complex exists in this case, the product being a mixture of a 1: 3 complex and a novel 1: 0.5 complex. The latter complex was prepared both mechanochemically and from solution, and characterized by infrared and solid-state 65Cu broadline NMR spectroscopy. Diagnostic ligand and metal-ligand bands in the IR and far-IR spectra are assigned for both polymorphs of CuSCN and for all of the complexes studied and are discussed in relation to the structures of the complexes.

Wide bandgap hole-transporting semiconductor copper(I) thiocyanate (CuSCN) has recently shown promise both as a transparent p-type channel material for thin-film transistors and as a hole-transporting layer in organic light-emitting diodes and organic photovoltaics. Herein, the hole-transport properties of solution-processed CuSCN layers are investigated. Metal-insulator-semiconductor capacitors are employed to determine key material parameters including: dielectric constant [5.1 (±1.0)], flat-band voltage [-0.7 (±0.1) V], and unintentional hole doping concentration [7.2 (±1.4) × 1017 cm-3]. The density of localized hole states in the mobility gap is analyzed using electrical field-effect measurements; the distribution can be approximated invoking an exponential function with a characteristic energy of 42.4 (±0.1) meV. Further investigation using temperature-dependent mobility measurements in the range 78-318 K reveals the existence of three transport regimes. The first two regimes observed at high (303-228 K) and intermediate (228-123 K) temperatures are described with multiple trapping and release and variable range hopping processes, respectively. The third regime observed at low temperatures (123-78 K) exhibits weak temperature dependence and is attributed to a field-assisted hopping process. The transitions between the mechanisms are discussed based on the temperature dependence of the transport energy. The wide bandgap p-type semiconductor copper(I) thiocyanate (CuSCN) has the potential to replace conventional hole-transport materials in numerous opto/electronics applications. This work provides a comprehensive analysis of the charge transport properties of solution-processed CuSCN layers. Various techniques are employed to evaluate the dielectric constant, flat-band voltage, unintentional doping concentration, density of states in the mobility gap, and hole-transport mechanisms.
