Sulfur-containing nitriles have important research value in the life sciences due to their diverse biological activities resulting from the sulfur and cyano functional groups. Herein, a copper-catalyzed cyanothiolation of N-tosylhydrazones with thiocyanates to generate alpha-arylthioalkanenitriles bearing sulfur-substituted quaternary carbon center atoms has been described. This novel protocol involves the procedure of copper carbene species promoting S-CN bond cleavage and C-CN/C-S bond reconstruction to introduce both sulfur and cyano groups onto a single carbon center. This cyanothiolation reaction will greatly enhance the synthetic utility of carbenoid species as new entries for the construction of diverse heteroatom-containing nitriles via cyanofunctionalization of metal-carbene species.

Phosphorescent organic light-emitting diodes (PhOLEDs) have attracted tremendous attention recently but still suffer serious efficiency roll-off at high luminance, which will significantly limit their practical application in the future. Here, using a spin-coated transparent CuSCN film as the hole-injection layer (HIL), we succeed in achieving high-performance blue PhOLEDs with extremely low efficiency roll-offs based on widely used host and guest materials in a conventional device structure; by thermal and current annealing treatments, the external quantum efficiency (EQE) is up to 12.5% at 8370 cd m-2, and the EQE roll-off can be as low as 2% at 10 000 cd m-2 and 7% at 20 000 cd m-2, respectively. The inorganic molecular semiconductor feature of CuSCN and the improved hole mobility after the annealing treatment were proved to be the main reasons for the highly stable PhOLEDs. The successful application of solution-processed CuSCN HIL for blue PhOLEDs with low efficiency roll-offs could provide important guidelines for the development of low-cost and highly efficient devices at high luminance.

Synthetic Route 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.
