Poly[[(pyridazine-kappaN)copper(I)]-mu3-thiocyanato- kappa3 N:S:S]

The crystal structure of the [Cu(NCS)-(C4H4N 2)]n was investigated. Each Cu atom was coordinated by one N atom of one pyridazine ligand and by one N and two S atoms of three symmetry-related thiocyanate anions within a distorted tetrahedron in the above compound. The compound was prepared by the reaction of CuSCN and pyridazine in acetonitrile in a teflon-lined steel autoclave at 373 K. It was observed that only one N atom of the pyridazine ligand was involved in Cu coordination. It was shown that the Cu atoms were connected via the thiocyanate anions, forming layers parallel to the ab plane.

Highly efficient organic solar cells based on a robust room-temperature solution-processed copper iodide hole transporter

Achieving high performance and reliable organic solar cells hinges on the development of stable and energetically suitable hole transporting buffer layers in tune with the electrode and photoactive materials of the solar cell stack. Here we have identified solution-processed copper(I) iodide (CuI) thin films with low-temperature processing conditions as an effective hole-transporting layer (HTL) for a wide range of polymer:fullerene bulk heterojunction (BHJ) systems. The solar cells using CuI HTL show higher power conversion efficiency (PCE) in standard device structure for polymer blends, up to PCE of 8.8%, as compared with poly(3,4-ethylenedioxy-thiophene):poly(styrenesulfonate) (PEDOT:PSS) HTL, for a broad range of polymer:fullerene systems. The CuI layer properties and solar cell device behavior are shown to be remarkably robust and insensitive to a wide range of processing conditions of the HTL, including processing solvent, annealing temperature (room temperature up to 200. C), and film thickness. CuI is also shown to improve the overall lifetime of solar cells in the standard architecture as compared to PEDOT:PSS. We further demonstrate promising solar cell performance when using CuI as top HTL in inverted device architecture. The observation of uncommon properties, such as photoconductivity of CuI and templating effects on the BHJ layer formation, is also discussed. This study points to CuI as being a good candidate to replace PEDOT:PSS in solution-processed solar cells thanks to the facile implementation and demonstrated robustness of CuI thin films.

Corrosion and fouling study of copper-based antifouling coatings on 5083 aluminum alloy

Potentiostatic and electrochemical impedance spectroscopy (EIS) were used to evaluate cuprous oxide (Cu2O) containing coating systems on the localized corrosion of 5083 marine-grade aluminum in simulated ocean water. Test panels coated with a complete coating system and flawed to simulate a coating defect were also exposed for a 3-month field immersion to evaluate differences between Cu2O and cuprous thiocyanate (CuSCN) pigments on fouling and corrosion behaviour. Optical microscopy, scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS) were used to evaluate deposits formed on the surfaces after exposure. Results imply that copper leaching from the Cu2O pigment can deposit on the surface marine-grade aluminum, with or without cathodic protection. Cathodic protection resulted in the formation of protective calcareous deposits at potentials more electronegative than ?1000 mV versus silver-silver chloride (Ag/AgCl). Cuprous oxide was shown to be a more resistant to biofouling than the cuprous thiocyanate, but there was an increased likelihood of coating delamination and localized corrosion with the former antifouling pigment.

Linear and cyclic tetranuclear copper(I) complexes containing anions of N,N?-bis(pyrimidine-2-yl)formamidine

The reaction of Kpmf (pmf = anion of N,N?-bis(pyrimidyl-2-yl) formamidine, Hpmf) with CuSCN afforded the complexes K[Cu4(pmF) 3(SCN)2], 1, and Cu4(pmf)4, 2. Reaction of 1 with [(n-Bu)4N]PF6 in THF gave the complex [(n-Bu)4N][Cu4(pmf)3(SCN)2], 3. Their structures were characterized by X-ray crystallography. Complexes 1 and 3 are the first linear tetranuclear complexes containing only Cu(I) atoms, while complex 2 is cyclic. The four Cu(I) atoms of complexes 1 and 3 are helically bridged by three tetradentate pmf- ligands. The [Cu 4(pmf)3(SCN)2]- anions of 1 show weak interactions with adjacent [K(THF)5]+ cations through the sulfur atoms, forming infinite chains which are subjected to a series of intermolecular pi-pi interactions. In complex 2, the pmf- ligands are coordinated to the copper atoms in bidentate fashion through the two central amine nitrogen atoms, leaving the pyrimidine nitrogen atoms uncoordinated. Unexpected fluxional behaviors were observed for complexes 1 and 3 in solution. By the DNMR analysis, the free energy of activation (DeltaGc?) for the exchange is 12.8 kcal mol-1 at 278 K (Tc), and the rate constant of exchange (Kc) is 470 s-1 for 1. The DeltaGc? and Kc are 12.6 kcal mol-1 at 273 K and 433 s-1, respectively, for 3. The Royal Society of Chemistry 2005.

An eco-friendly and inexpensive solvent for solution processable CuSCN as a hole transporting layer in organic solar cells

During past few years, significant research on solution-processable deposition of copper(I)thiocyanate (CuSCN) as an efficient hole transporting layer (HTL) for excitonic solar cells have been successfully reported. Surprisingly, till now only two solvents diisopropyl sulfide and diethyl sulfide are known which have been used for CuSCN film deposition as a HTL for device fabrication. Here, we have used eco-friendly and inexpensive solvent dimethyl sulfoxide (DMSO) for solution processed thin film deposition of CuSCN for organic solar cells. The photovoltaic devices were fabricated using two different donor polymers PCDTBT and PTB7 blended with PC71BM as an acceptor material with device structure of ITO/CuSCN/active layer/Al. The power conversion efficiency (PCE) based on CuSCN using DMSO as a deposition solvent have been achieved up to 4.20% and 3.64% respectively, with relative higher fill factor (FF) as compared to previously reported values in literature. The resultant HTLs were characterized by UV?vis?NIR spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM) and atomic force microscope (AFM) for better understanding.

Copper(i) complexes with phosphine derived from sparfloxacin. Part I – structures, spectroscopic properties and cytotoxicity

In this paper we present new copper(i) iodide or copper(i) thiocyanate complexes with hydroxymethyldiphenylphosphine (PPh2(CH2OH)) or phosphine derivatives of sparfloxacin, a 3rd generation fluoroquinolone antibiotic agent (PPh2(CH2-Sf)) and 2,9-dimethyl-1,10-phenanthroline (dmp) or 2,2?-biquinoline (bq) auxiliary ligands. The synthesised complexes were fully characterised by NMR and UV-Vis spectroscopy as well as by mass spectrometry. Selected structures were additionally analysed using X-ray and DFT methods. All complexes proved to be stable in solution in the presence of water and atmospheric oxygen for several days. The cytotoxic activity of the complexes was tested against two cancer cell lines (CT26 – mouse colon carcinoma and A549 – human lung adenocarcinoma). Applying two different incubation times, the studies enabled a preliminary estimation of the dependence of the selectivity and the mechanism of action on the type of diimine and phosphine ligands. The results obtained showed that complexes with PPh2(CH2-Sf) are significantly more active than those with PPh2(CH2OH). On the other hand, the relative impact of diimine on cytotoxicity is less pronounced. However, the dmp complexes are characterised by strong inhibitory properties, while the bq ones are rather not. This confirms the interesting and promising biological properties of the investigated group of copper(i) complexes, which undoubtedly are worthy of further biological studies.

Front dielectric and back plasmonic wire grating for efficient light trapping in perovskite solar cells

Thin film perovskite solar cells (PSCs) based on (CH3NH3PbI3) have been emerged as good alternatives to conventional silicon solar cells due to their low cost, low fabrication temperature, high carrier collection efficiency, and high-power conversion efficiency (PCE). However, the small thickness of thin film solar cells limits light absorption compared to thick solar cells. In this work, we proposed a theoretical design for enhancing light absorption to achieve maximum theoretical photocurrent using front dielectric and back plasmonic wire grating. Using finite element method (FEM) three-dimensional optical model, the optimum size and periodicity of the studied wire grating nanostructures were identified. Additionally, the electrical model revealed a satisfactory enhancement in PCE over that of the planar structure counterpart. The simulation results showed an average enhancement of 22.4% in total generation rate for the entire simulated wavelength, and more than 85% enhancement in narrow-band wavelength compared to the planar structure counterpart.

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.Computed Properties of CCuNS, you can also check out more blogs about1111-67-7
