In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. Application In Synthesis of Cuprous thiocyanate. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate

Solid-state dye-sensitized solar cells of the type TiO2/dye/ CuSCN have been made with thin Al2O3 barriers between the TiO2 and the dye. The Al2O3-treated cells show improved voltages and fill factors but lower short-circuit currents. Transient photovoltage and photocurrent measurements have been used to find the pseudo-first-order recombination rate constant (kpfo) and capacitance as a function of potential. Results show that kpfo is dependent on Va¿¿ with the same form as in TiO2/dye/electrolyte cells. The added Al2O3 layer acts as a “tunnel barrier”, reducing the kpfo and thus increasing V a¿¿. The decrease in KpfO also results in an increased fill factor. Capacitance vs voltage plots show the same curvature (a¿¼150 mV/decade) as found in Tio2dye/ electrolyte cells. The application of one AL2O3 layer does not cause a significant shift in the shape or position of the capacitance curve, indicating that changes in band offset play a lesser role in the observed Va¿¿ increase. Cells made with P25 TiO2 have, on average, 2.5 times slower recombination rate constants (longer lifetimes) than those made with colloidal TiO 2. The cells with P25 also show 2.3 times higher trap density (DOS), which results in little change in the Va¿¿ between the two types of TiO2. It is further noted that the recombination current in these cells cannot be calculated from the total charge times the first order rate constant. A 2005 American Chemical Society.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst, does not appear in the overall stoichiometry of the reaction it catalyzes. you can also check out more blogs about Electric Literature of 80-73-9!, Application In Synthesis of Cuprous thiocyanate

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.

Poly(methyl methacrylate) (PMMA) was synthesized via atom transfer radical polymerization (ATRP). As a catalyst copper(I)thiocyanate (CuSCN) was used with N-n-pentyl-2-pyridylmethanimine as a ligand. Infrared spectroscopy and matrix assisted laser desorption ionization time-of-flight mass spectrometry were used to characterize the synthesized polymers. From this it was clear that at least to some extent thiocyanate was present as end groups of the PMMA chains. This observation is discussed in view of a phenomenon called halogen exchange, which has been reported before for bromine/chlorine exchange in ATRP.

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.

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.

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.

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
