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.

Mechanism of Formation of Copper Thiocyanate on the Copper Anode

A PRIMARY (barrier) film forms on the copper anode at an underpotential relative to the secondary (porous) film and exhibits a pre-peak or shoulder at -0.19 V (vs.SHE), for a 0.1 mol dm-3 KSCN electrolyte.The anodic peak current for the primary film is linearly dependent upon the sweep rate, while potential steps into the primary film region produce monotonic current decays with j = kt-1, consistent with a place-exchange mechanism for the initial formation of the barrier film.Upon stirring, the size of the primary film peak decreases as hydrogen evolution competes with the film-formation process.A porous CuSCN film begins to form at potentials 50-100 mV more positive than the barrier film, producing a larger peak at 0.01 V (0.1 mol dm-3 KSCN), equivalent to a film of 15-20 monolayers, with thicker films formed in more concentrated thiocyanate solutions.The anodic peak current for the porous film and the potential change to reach the peak are both proportional to the square root of the sweep rate, which is consistent with a model for film growth controlled by the resistance across the underlying barrier film.Raman spectroscopy reveals at least two distict S-bonded CuSCN species, one of which is lost upon partial reduction of the film, and is due to the barrier film.The remaining species has the same Raman spectrum as crystalline CuSCN.

Pentafluoroethylation of Arenediazonium Tetrafluoroborates Using On-Site Generated Tetrafluoroethylene

Copper-mediated pentafluoroethylation of arenediazonium tetrafluoroborates with tetrafluoroethylene (TFE) on-site generated from TMSCF3 has been developed as a new method to prepare pentafluoroethyl arenes. The active pentafluoroethylation reagent ?CuC2F5? is pre-generated from CuSCN, TFE and CsF, and its generation and further reaction are strongly solvent-dependent. This pentafluoroethylation reaction represents the first example of Sandmeyer-type pentafluoroethylation, which exhibits good functional group tolerance and potential applications for the synthesis of complicated bioactive compounds.

Syntheses and crystal structures of

Through the reaction of CuSCN with AsPh-(SiMe3)2 in the presence of tertiary phosphines the compounds [Cu4(As4Ph4)2(PRR? 2)4] (1-3) (1: R = R? = nPr, 2: R = R? = Et; 3: R = Me, R? = nPr) and [Cu14(AsPh)6(SCN)2-(PEt2Ph) 8] (4) can be synthesised. Using CuCl instead of CuSCN results to the cluster complexes [Cu14(AsPh)6Cl2(PRR?2) 8] (5-6) (5: R = R? = Et; 6: R = Me, R? = nPr), [Cu12(AsPh)6(PPh3)6] (7) and [Cu10(AsPh)4Cl2-(PMe3)8] (8).

Aqueous phase self-assembly of nanoscale p-n heterojunctions

Methods, adapted from photographic microcrystal growth technology, are used to assemble organized ternary organo-inorganic, nanoscale heterostructures. The resulting ensemble consists of free-standing, oriented AgBr microcrystals, upon the a??111a?? surfaces of which is self-assembled a monolayer of spectrally sensitizing dye, and upon the corners of the hexagonally shaped AgBr substrates are epitaxially grown nanoscale p-type CuSCN nodules. EPR spectroscopy and photophysical measurements are employed to show that the ensembles are capable of separating photogenerated geminate pairs. One of the remarkable features of this approach is that it utilizes the ultrafast kinetics of aqueous precipitation and, thus, allows the assembly of heterostructures at rates of 1010/sA¡¤L, or greater.

The Role of Charge Selective Contacts in Perovskite Solar Cell Stability

Lead halide perovskite solar cells have rapidly achieved high efficiencies comparable to established commercial photovoltaic technologies. The main focus of the field is now shifting toward improving the device lifetime. Many efforts have been made to increase the stability of the perovskite compound and charge-selective contacts. The electron and hole selective contacts are responsible for the transport of photogenerated charges out of the solar cell and are in intimate contact with the perovskite absorber. Besides the intrinsic stability of the selective contacts themselves, the interfaces at perovskite/selective contact and metal/selective contact play an important role in determining the overall operational lifetime of perovskite solar cells. This review discusses the impact of external factors, i.e., heat, UV-light, oxygen, and moisture, and measured conditions, i.e., applied bias on the overall stability of perovskite solar cells (PSCs). The authors summarize and analyze the reported strategies, i.e., material engineering of selective contacts and interface engineering via the introduction of interlayers in the aim of enhancing the device stability of PSCs at elevated temperatures, high humidity, and UV irradiation. Finally, an outlook is provided with an emphasis on inorganic contacts that is believed to be the key to achieving highly stable PSCs.

Boric Ester and Thiourea as Coupling Partners in a Copper-Mediated Oxidative Dehydrosulfurative Carbon-Oxygen Cross-Coupling Reaction

A copper-mediated oxidative dehydrosulfurative carbon-oxygen cross-coupling reaction with boric ester and six-membered cyclic thiourea for single-step production of densely substituted 2-alkoxypyrimidines incorporated in a privileged scaffold is described. This is the first demonstration of boric ester acting as an alkoxy donor in a metal-catalyzed coupling reaction to produce ether. The reaction method offers a shortcut for producing 2-alkoxypyrimidine derivatives with rapid diversification and expands the utility of boric ester and the scope of Liebeskind-Srogl-type reactions.

Mixed-valence CuIICuI15I17 cluster builds up a 3D metal-organic framework with paramagnetic and thermochromic characteristics

Four cubane-like CU4I4 units are assembled around an iodine atom to form the giant, mixed-valent CuIICuI 15I17 cluster. The CuIICuI 15I17 cluster and a bipyrazole linker form a 3D open framework with paramagnetic and thermochromic properties. This paper also touches on the resemblance of this cluster to the self-similar object of a Sierpinski tetrahedron.

Powder pressed cuprous iodide (CuI) as a hole transporting material for perovskite solar cells

This study focuses on employing cuprous iodide (CuI) as a hole-transporting material (HTM) in fabricating highly efficient perovskite solar cells (PSCs). The PSCs were made in air with either CuI or 2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene (spiro-OMeTAD) as HTMs. A simple and novel pressing method was employed for incorporating CuI powder layer between perovskite layer and Pt top-contact to fabricate devices with CuI, while spiro-OMeTAD was spin-coated between perovskite layer and thermally evaporated Au top-contact to fabricate devices with spiro-OMeTAD. Under illuminations of 100 mW/cm2 with an air mass (AM) 1.5 filter in air, the average short-circuit current density (JSC) of the CuI devices was over 24 mA/cm2, which is marginally higher than that of spiro-OMeTAD devices. Higher JSC of the CuI devices can be attributed to high hole-mobility of CuI that minimizes the electron-hole recombination. However, the average power conversion efficiency (PCE) of the CuI devices were lower than that of spiro-OMeTAD devices due to slightly lower open-circuit voltage (VOC) and fill factor (FF). This is probably due to surface roughness of CuI powder. However, optimized devices with solvent-free powder pressed CuI as HTM show a promising efficiency of over 8.0 % under illuminations of 1 sun (100 mW/cm2) with an air mass 1.5 filter in air, which is the highest among the reported efficiency values for PSCs fabricated in an open environment with CuI as HTM.
