Reference of 1111-67-7In an article, once mentioned the new application about 1111-67-7.

Ultra-high transparent p-type copper iodide (CuI) thin films were fabricated by solid iodization of evaporated Cu precursor layers at room temperature. The effect of the thickness on microstructure, binding energy and optoelectrical properties is systematically studied. X-ray diffraction measurements show the polycrystalline nature of the CuI thin films with zincblende type structure. The X-ray photoelectron spectroscopy (XPS) analysis indicates that the oxidation state of Cu is +1 and the estimated value of [Cu]/[I] at 100 nm is 0.87. Excess iodide ions trap considerable holes, causing CuI thin films to exhibit the p-type conductivity, which is consistent with the results of the Hall effect measurement and the non-linear characteristics of the CuI/ITO structure. Moreover, the CuI thin films with thickness of 100 nm exhibits an ultra-high optical transmittance of 95.5% in the wavelength of 380?780 nm and an excellent conductivity of 34 S/cm. These results prove the great potential of CuI as a promising p-type optoelectronic material.

Electric Literature of 1111-67-7, Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. Mentioned the application of 1111-67-7, Name is Cuprous thiocyanate.

The meagre (structurally defined) array of 1:2 silver(I) (pseudo-)halide:unidentate nitrogen base adducts is augmented by the single-crystal X-ray structural characterization of the 1:2 silver(I) thiocyanate:piperidine (‘pip’) adduct. It is of the one-dimensional ‘castellated polymer’ type previously recorded for the chloride: ?Ag(pip) 2(mu-SCN)Ag(pip)2? a single bridging atom (S) linking successive silver atoms. By contrast, in its copper(I) counterpart, also a one-dimensional polymer, the thiocyanate bridges as end-bound SN-ambidentate: ?CuSCNCuSCN? A study of the 1:1 silver(I) bromide:quinoline (‘quin’) adduct is recorded, as the 0.25 quin solvate, isomorphous with its previous reported ‘saddle polymer’ chloride counterpart. Recrystallization of 1:1 silver(I) iodide:tris(2,4,6-trimethoxyphenyl)phosphine (‘tmpp’) mixtures from py and quinoline (‘quin’)/acetonitrile solutions has yielded crystalline materials which have also been characterized by X-ray studies. In both cases the products are salts, the cation in each being the linearly coordinated silver(I) species [Ag(tmpp)2]+, while the anions are, respectively, the discrete [Ag5I7(py)2]2- species, based on the already known but unsolvated [Cu5I 7]2- discrete, and the [Ag5I7] (?|?)2- polymeric, arrays, and polymeric [Ag5I6(quin)](?|?)-. The detailed stereochemistry of the [Ag(tmpp)2]+ cation is a remarkably constant feature of all structures, as is its tendency to close-pack in sheets normal to their P-Ag-P axes. The far-IR spectra of the above species and of several related complexes have been recorded and assigned. The vibrational modes of the single stranded polymeric AgX chains in [XAg(pip) 2](?|?) (X = Cl, SCN) are discussed, and the assignments nu(AgX) = 155, 190 cm-1 (X = Cl) and 208 cm -1 (X = SCN) are made. The nu(AgX) and nu(AgN) modes in the cubane tetramers [XAg(pip)]4 (X = Br, I) are assigned and discussed in relation to the assignments for the polymeric AgX:pip (1:2) complexes, and those for the polymeric [XAg(quin)](?|?) (X = Cl, Br) compounds. The far-IR spectra of [Ag(tmpp)2]2[Ag 5I7(py)2] and its corresponding 2-methylpyridine complex show a single strong band at about 420 cm-1 which is assigned to the coordinated tmpp ligand in [Ag(tmpp)2] +, and a partially resolved triplet at about 90, 110 and 140 cm -1 which is assigned to the nu(AgI) modes of the [Ag 5I7L2]2- anion. An analysis of this pattern is given using a model which has been used previously to account for unexpectedly simple nu(CuI) spectra for oligomeric iodocuprate(I) species.

Treatment of [Et4N][Tp*WS3] (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) (1) with CuX (X = Br, SCN) and PPh3 or 1,1-bis(diphenylphosphino)methane (dppm) produced two neutral trinuclear clusters [Tp*W(mu3-S)(mu-S)2Cu 2Br(PPh3)] (2) and [Tp*W(mu3-S)(mu-S) 2Cu2(SCN)(dppm)]2·MeCN·Et 2O (3·MeCN·Et2O). Reactions of 1 with [Cu(MeCN)4]PF6, NH4PF6 and 1,3-bis(diphenylphosphino)propane (dppp), N,N-bi(diphenylphosphanylmethyl)-2- aminopyridine (bdppmapy), N,N,N?,N?-tetra(diphenylphosphanylmethyl) ethylenediamine (dppeda), or 1,4-N,N,N?,N?- tetra(diphenylphosphanylmethyl)benzenediamine (dpppda) afforded four clusters containing butterfly-shaped [Tp*WS3Cu2] cores, [Tp*W(mu3-S)(mu-S)2Cu2(dpppds)] (PF6)·1.25MeCN (dpppds = 1,3-bis(diphenylphosphino)propane disulfide) (4·1.25MeCN), [Tp*W(mu3-S)(mu-S) 2Cu2(bdppmapy)](PF6)·3MeCN (5·3MeCN) and {[Tp*W(mu3-S)(mu-S)2Cu 2]2(L)]}(PF6)2·Sol (6·Et2O: L = dppeda, Sol = Et2O; 7·1.25MeCN: L = dpppda, Sol = 1.25MeCN). Compounds 2-7 were characterized by elemental analysis, IR, UV-Vis, 1H and 31P{1H} NMR spectra, electrospray ion mass spectra (ESI-MS) and single-crystal X-ray diffraction. Compound 2 or 3 has a butterfly-shaped [Tp*WS 3Cu2] core in which one [Tp*WS3] unit binds two Cu(i) centers via one mu3-S and two mu-S atoms. In the cationic structure of 4 or 5, one in situ-formed dpppds or bdppmapy combines with the [Tp*WS3Cu2] core via each of its two S atoms or two P atoms coordinated at each Cu(i) center. In the bicationic structure of 6 or 7, two [Tp*WS3Cu2] cores are linked by one dppeda or dpppda bridge to form a bicyclic structure. The isolation of 2-7 with unstable [Tp*WS3Cu2] cores may be ascribed to the coordination of P- or S-donor ligands at Cu(i) centers of these cores. The third-order nonlinear optical (NLO) properties of 2-7 in DMF were also investigated by using the femtosecond degenerate four-wave mixing (DFWM) technique at 800 nm.

Thirty-two aryl-substituted 2-benzothiazolamines have been tested for their ability to modulate sodium flux in rat cortical slices. A QSAR analysis, applied to these derivatives, showed a trend toward increasing potency as sodium flux inhibitors with increasing lipophilicity, decreasing size, and increasing electron withdrawal of the benzo ring substitutents. Additionally, 4- or 5-substitution of the benzo ring was found to decrease potency. The combination of increased lipophilicity, small size, and electron withdrawal severely limited which groups were tolerated on the benzo ring, thus suggesting that the optimal substitution patterns have been prepared within this series. Nine of these compounds were potent inhibitors of veratridine-induced sodium flux (NaFl). These nine compounds also proved to be anticonvulsant in the maximal electroshock (MES) assay. Fourteen additional 2-benzothiazolamines demonstrated activity in the MES screen, yet exhibited no activity in the NaFl assay. These derivatives may be interacting at the sodium channel in a manner not discernible by the flux paradigm, or they may be acting by an alternative mechanism in vivo.

Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials.

Six mixed-valence CuICuII compounds containing 4?-(4-pyridyl)-2,2?:6?,2?-terpyridine (L1) or 4?-(2-pyridyl)-2,2?:6?,2?-terpyridine (L2) were prepared under the hydrothermal and ambient conditions, and their crystal structures were determined by single-crystal X-ray diffraction. Selection of CuCl 2·2H2O or Cu(CH3COO)2· H2O with the L1 ligand and NH4SCN, KI, or KBr under hydrothermal conditions afforded 1-dimensional mixed-valence Cu ICuII compounds [Cu2(L1)(mu-1,1-SCN)(mu-Cl) Cl]n (1), [Cu2(L1)(mu-l)2Cl]n (2), [Cu2(L1)(mu-Br)2Br]n (3), and [Cu 2(L1)(mu-1,3-SCN)2(SCN)]n (4), respectively. Compound 5, prepared by layering with CuSCN and L1, is a 2-dimensional bilayer structure. In compounds 1-5, the L1 ligand and X (X = Cl, Br, I, SCN) linked between monovalent and divalent copper atoms resulting in the formation of mixed-valence rectangular grid-type M4L4 or M 6L6 building blocks, which were further linked by X (X = Cl, Br, I, SCN) to form 1- or 2-dimensional polymers. The sizes of M 4L4 units in 1-4 were fine-tuned by the sizes of X linkers. Reaction of Cu(CH3COO)2·H2O with L2 and NH4SCN under hydrothermal conditions gave mixed-valence CuICuII compound [Cu2(L2)(mu-1,3-SCN) 3]n (6). Unlike those in 1-5, the structure of 6 was constructed from thiocyanate groups and the pendant pyridine of L2 left uncoordinated. The temperature-dependent magnetic susceptibility studies on compounds 1 and 4 showed the presence of mixed-valence electronic structure.
