THE EFFECTIVENESS OF COPPER(I) COMPOUNDS AS CATALYSTS THE COUPLING OF PHENYLLITHIUM WITH PRIMARY ALKYL HALIDES AND TOSYLATES

Various uncomplexed and complexed Cu(I) salts, Li2CUCl4, Li2CuCl3, Ph2CuLi and PhCu, have been tested as catalysts in the coupling reactions of phenyllithium with 2-chloroethanol, ethyl bromide, 2-chloroethyl tosylate and ethyl tosylate. CuBr.Me2S, CuCN, CuI.PBu3-n and CuI have been found to be most effective and selective catalysts in diethyl ether, respectively, for these couplings. The catalytic activity in Cu(I) catalyzed coupling reactions of phenyllithium depends on the reaction conditions, onthe nucleofugal group, and on the 2-heteroatom functionality of the sub strate.

Semiconductor growth and junction formation within nano-porous oxides

We have developed semiconductor growth techniques for the coating and filling of nanopores in ceramic-type substrates. The main idea behind this research is to use the large inner surface of ceramics as a template for the realization of semiconductor heterojunctions with extremely large interface area. As porous substrates we use lightly sintered nanocrystalline TiO2 of 5-10 mum thickness. The pore volume in these substrates is approx. 50% and the average pore diameter is 30-50 nm. We are able to establish nanometer thick coatings on the inner surfaces of these substrates or – in a different technique – fill the pore volume with (100 ¡À 3)% efficiency. The growth techniques involve chemical and electrochemical methods from liquid solutions. Binary, ternary and, most recently, quaternary compounds of the II-VI and I-III-VI material systems were prepared.

Synthesis and crystal structure of 4,7,13,16,21,24-hexaoxa-1,10- diazoniabicyclo[8.8.8]hexacosane bis[dichloro(thiocyanato)copper(II)]

A new complex salt [4,7,13,16,21,24-hexaoxa-1,10-diazoniabicyclo[8.8.8] hexacosane bis[dichloro(thiocyanato)copper(II)], [H2(Crypt-222)] [CuCl2(SCN)]2, is synthesized and studied by X-ray diffraction analysis. The crystals are monoclinic (space group C2/c, a = 14.603 A, b = 8.330 A, c = 25.091 A, beta = 100.76, Z = 4). The structure is solved by a direct method and refined by the full-matrix least-squares method in the anisotropic approximation to R = 0.047 for 2943 independent reflections (CAD-4 automated diffractometer, lambdaMoK alpha radiation). The Cu2+ cations and Cl- and SCN- anions form infinite polymeric chains of spiro-conjugated alternating centrosymmetric four-membered CuCl2Cu cycles and eight-membered Cu(SCN)2Cu cycles through coordination bonds. The coordination polyhedron of the Cu2+ cation is a distorted trigonal bipyramid. The [H2(Crypt-222)]2+ dication contains trifurcate N+-(…O)3 bonds on axis 2. Nauka/Interperiodica 2007.

Two novel anion cluster compounds with a planar ‘open’ structure [Et4N]2[MS4Cu4(SCN)4(2-pic)4] (M = W, Mo; 2-pic = 2-methylpyridine): Synthesis, structural characterization, nonlinear response and large optical limiting properties

The title compounds [Et4N]2[MS4Cu4(SCN)4(2-pic)4] (M = W l, Mo 2) have been synthesized by the reaction of (Et4N)2MS4, Cu(SCN) and 2-picoline (2-pic, 2-methylpyridine). Single crystal X-ray diffraction data show that the anion clusters [MS4Cu4(SCN)4(2-pic)4]2 have the planar ‘open’ structure with four Cu atoms in three kinds of coordination modes. Nonlinear optical properties of these two clusters are investigated with a 8 ns pulsed laser at 532 nm. The two clusters exhibit large optical limiting performance, with limiting threshold values of 0.3 J cm2 for 1, 0.5 J cm2 for 2, and self-defocusing effects, effective nonlinear refractive index /;2 = -6.84 x 1012 esu (esu = 7.162 x 10 m5 v2) 1 and 2 = -8.48 x 1012 esu 2 respectively. Both compounds show reverse saturable absorption: a2 = 3.1 x l(T6 m W1 for 1 and a2 = 3.2 x 106 m W’ for 2 in 6.98 x 104 mol dm3 and 7.44 x 10 mol dm3 DMF solution respectively. The corresponding effective NLO susceptibilities %m are 6.5 x 108 esu 1 and 8.9 x 108 esu 2 while the corresponding hyperpolarizabilities (y(I) = 9.42 x 1032 esu and ym = 1.29 x 1031 esu) are also reported.

New ambient pressure organic superconductor (BEDT-TTF)2Cu(NCS)2 with Tc above 10 K

An ambient pressure superconductivity in (BEDT-TTF)2Cu(NCS)2 is reported. The superconducting critical temperature is the highest among the organic superconductors so far obtained (Tc=10.4 K). The salt prepared using deuterated BEDT-TTF is also an ambient pressure superconductor with a slightly higher Tc (11.0 K). The crystal structure analysis and resistivity measurement revealed the highly two-dimensional nature of this salt. The temperature dependence of normal resistivity, superconducting critical field, quantum oscillation of resistivity and so on are reported down to 0.5 K and up to 13.5 T. The superconducting upper critical field shows a peculiar temperature dependence, and the parallel critical field behavior is ascribed to the dimensional crossover effect. The quantum oscillation is understood as the Shubnikov-de Haas effect, and the possible Fermi surface is presented. The possible superconducting mechanisms are also discussed.

Charge-Transporting Materials for Perovskite Solar Cells

The power conversion efficiency of perovskite solar cells (PSCs) has been certified as ?22.1%, approaching the best single crystalline silicon solar cells. The improvement in the performance of PSCs could be achieved through the testing of novel materials in the device. This review briefly discusses the systematic introduction about several inorganic and organic electron-transporting materials (ETMs) and hole-transporting materials (HTMs) for efficient PSCs. The transport mechanism of electrons and holes in different ETMs/HTMs is also discussed on the basis of energy band diagrams with respect to the perovskite absorber. Moreover, the introduction of appropriate interfacial materials, hybrid ETMs, and doping is discussed to optimize the interfacial electronic properties between the perovskite layer and the charge-collecting electrode.
