Synthesis, structure and fluorescence properties of a coordination polymer [Cu2(SCN)4(BPX)]n with 1D ladder-shaped structure

A coordination polymer, [Cu2(SCN)4(BPX)]n (BPX = 1,4-bis(pyridinium) xylol) was synthesized and characterized by IR spectrum, fluorescence spectrum and single crystal X-ray diffraction. Crystal structure revealed that the title compound crystallized in monoclinic system with space group P2(1)/c, a = 5.7540(7)A, b = 12.7203(15)A, c = 17.598(2)A, = 94.9940(10). Two SCN-ions served as bridging ligands to link two Cu(I) ions, giving rise to an eight-member ring. Furthermore, copper atom and sulfur atom of the eight-member ring bonded sulfur atom and copper atom of adjacent eight-member ring through the formation of Cu-S to form a small four-member ring. Thus, innumerable eight-member rings alternately linked four-member rings each other to form an infinite one-dimensional ladder-shaped structure.

Novel Cu(I) complexes of functionalized phosphines

Novel tertiary phosphines R?PR2 with additional functionalities in the substituent R have been designed and prepared according to literature procedures. The coordination behavior of the additional functionality in the organic moiety and the phosphorus atom towards different Cu(I) salts was investigated. These reactions resulted in polynuclear complexes with unexpected structures involving Cu(I) atoms with different coordination numbers in the same compound.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 1111-67-7, you can also check out more blogs aboutApplication of 1111-67-7

Improving the efficiency and stability of inverted perovskite solar cells by CuSCN-doped PEDOT:PSS

Hole transport layer (HTL) is important in inverted perovskite solar cells (PSCs) to facilitate the hole extraction and suppress the charge recombination for high device performance. Based on the widely used HTL material of poly(ethylenedioxythiophene) (PEDOT):poly(styrenesulfonate) (PSS), we proposed a new HTL modification method using the widely available copper(I) thiocyanate (CuSCN); the doping of CuSCN NH3 [aq] in PEDOT:PSS followed by low-temperature annealing results in reduced energy barrier, improved charge extraction efficiency and increased the mean size of perovskite crystal of the PEDOT:PSS-CuSCN HTL-based inverted PSCs. Significantly improved device performance was observed with open current voltage over 1.0 V and power conversion efficiency (PCE) up to 15.3%, which is 16% higher in PCE than that of the PEDOT:PSS-based PSCs. More impressively, with a lower acidity than PEDOT:PSS, the PEDOT:PSS-CuSCN HTL enables excellent long-term stability of the inverted PSCs, exhibiting almost doubly improved device stability at the same storage condition. Thus, the successful application of CuSCN doping in PEDOT:PSS HTLs should provide a novel approach for the development of high-performance HTLs for highly efficient and stable PSCs.

Electron and hole transport layers optimization by numerical simulation of a perovskite solar cell

In this paper an n-i-p perovskite solar cell was studied using SCAPS simulator. The primary solar cell’s structure is FTO/ITO/Perovskite/PEDOT:PSS/Au which has achieved a power conversion efficiency of eta ? 13.94%. In order to enhance its performance, several materials were suggested as electron and hole transport layers (ETL and HTL). Among the proposed ETL materials it was found that Zinc oxide (ZnO) and titanium dioxide (TiO2) are the most adequate materials. For the HTL materials, among the proposed materials Copper (I) thiocyanate (CuSCN) forms the appropriate one. Also, the solar cell performance was improved by optimizing the absorber thickness which was found to be 1 mum. With these considerations the power conversion efficiency reached 25.02%. In addition, the detrimental effect of defects at the perovskite/TiO2 interface on the solar cell performance is also presented.

Structure-activity relationship of 3-substituted N-(pyridinylacetyl)-4- (8-chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-ylidene)- piperidine inhibitors of farnesyl-protein transferase: Design and synthesis of in vivo active antitumor compounds

Novel tricyclic Ras farnesyl-protein transferase (FPT) inhibitors are described. A comprehensive structure-activity relationship (SAR) study of compounds arising from substitution at the 3-position of the tricyclic pyridine ring system has been explored. In the case of halogens, the chloro, bromo, and lode analogues 19, 22, and 28 were found to be equipotent. However, the fluoro analogue 17 was an order of magnitude less active. Whereas a small alkyl substituent such as a methyl group resulted in a very potent FPT inhibitor (SCH 56580), introduction of bulky substituents such as tert-butyl compound 33, or a phenyl group, compound 29, resulted in inactive FPT inhibitors. Polar groups at the 3-position such as amine 5, alkylamino 6, and hydroxyl 12 were less active. Whereas compound SCH 44342 did not show appreciable in vive antitumor activity, the 3-bromo-substituted pyridyl N- oxide amide analogue 38 was a potent FPT inhibitor that reduced tumor growth by 81% when administered q.i.d. at 50 mpk and 52% at 10 mpk. These compounds are nonpeptidic and do not contain sulfhydryl groups. They selectively inhibit FPT and not geranylgeranyl-protein transferase-1 (GGPT-1). They also inhibit H-Ras processing in COS monkey kidney cells and soft agar growth of Ras-transformed cells.

Stereocontrol in a ytterbium triflate-catalyzed 1,3-dipolar cyclo-addition reaction of carbonyl ylide with N-substituted maleimides and dimethyl fumarate

The addition of Yb(OTf)3 (10 mol%) in a Rh2(OAc)4-catalyzed reaction of o-(methoxycarbonyl)-alpha-diazoacetophe-none with N-methylmaleimide in CH2Cl2 or in diethyl ether gave cycloadducts with high endo-selectivity (endo:exo = 95:5-96:4). The CuOTf (20 mol%)-or CuCl-Yb(OTf)3 (5 mol%)-catalyzed reaction also gave 1,3-dipolar cycloadducts in an endo-selective manner (endo:exo = 94:6). On the other hand, a reaction using only Rh2(OAc)4 (5 mol%) as the catalyst in benzene under reflux gave cycloadducts with exo-selectivity (endo:exo = 11:89). The reaction of N-ethyland N-phenylmaleimides under the same conditions showed a similar tendency in terms of the stereoselectivity.

Thiolate layers on metal sulfides characterised by XPS, ToF-SIMS and NEXAFS spectroscopy

Surface spectroscopic characterisation of some Cu and Ag thiolate multilayers on metal and metal sulfide substrates was undertaken to establish unequivocally the composition and possible orientation of the multilayer species. This information was sought to attempt to explain the undiminished floatability of sulfide minerals observed for collector coverage exceeding a monolayer. The thiol collectors investigated were dithiophosphate and 2-mercaptobenzothiazole (MBT), and bulk CuMBT and AgMBT complexes were prepared for comparison with the corresponding multilayers. Surface optimised synchrotron X-ray photoelectron spectra and partial electron yield near-edge X-ray absorption fine structure (NEXAFS) spectra confirmed that the Cu dithiolate, detected by secondary ion mass spectroscopy (SIMS), was no more than a minor constituent of the corresponding multilayer. The photoelectron spectra for multilayer CuMBT and AgMBT were similar to those for the corresponding bulk complexes. NEXAFS spectroscopy detected some CuII in bulk CuMBT prepared from cupric ions but not cuprous. The SIMS data were consistent with multilayer patches or islands on top of a chemisorbed monolayer and hence continued exposure of the monolayer in the presence of the multilayer. For each multilayer investigated, the SIMS data provided no evidence to support a multinuclear cluster structure as is present in the corresponding bulk thiolate, but nor could they exclude such a possibility. Angle-dependent NEXAFS spectroscopy at the N K-edge confirmed that MBT monolayers were aligned and revealed that the metal thiolate multilayer was not aligned relative to the substrate, but might nevertheless have been ordered in a cluster structure. It was surmised that undiminished floatability of sulfide minerals with multilayer collector coverage could probably be attributed to the patch-wise nature of the multilayer.
