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.

Computed Properties of C10H16CuO4In an article, once mentioned the new application about 13395-16-9.

The reactions of salicylaldehyde oxime (H2salox) with Cu II precursors yielded the known complexes [Cu(Hsalox)2] (1) and [Cu(Hsalox)2]n (2), as well as complexes [Cu 3(salox)(L1)(L2)]·MeCN (3·MeCN), [CuCl(L1)] (4) and [Cu2Na(O2CMe) 5(HO2CMe)]n (5), where L1 – = o-O-C6H4-CHNO-C(CH3)NH and L23- = o-O-C6H4-CHNO-C(o-O-C 6H4)N. L1- was formed in situ via the nucleophilic addition of the oximato O-atom of salox2- to the unsaturated nitrile group of the MeCN reaction solvent. L2 3- is also formed in situ probably through the nucleophilic attack of the oximato O-atom to the unsaturated nitrile group of salicylnitrile; the latter, although not directly added to the reaction mixture, can be produced via the dehydration of salox2-. Compounds 1 and 2 contain Hsalox – bound to the metal center in two different coordination modes; they both contain the same mononuclear unit, however a 2D network is generated in 2 due to a relatively long Cu-Ooximato bond. Compound 3 contains three different ligands, i.e. salox2-, L1- and L 23-, which act as mu3-kappa2O: kappaO?:kappaN, kappaO:kappaN:kappaN? and mu3-kappa2O:kappa2N:kappaO?: kappaN?, respectively, whereas 4 consists of a square planar Cu II atom bound to a kappaO:kappaN:kappaN? L 1- and a chloride ion. Compound 5 consists of dinuclear [Cu2(O2CMe)5(HO2CMe)]- units and Na+ ions assembled into an overall 3D network structure. Magnetic susceptibility measurements from polycrystalline samples of 2 and 5 gave best-fit parameters J = +0.36 cm-1 (H = -JS? iS?j) and J = -360 cm-1, zj = +20 cm -1 (H = -JS?iS?j – zJ?S z?S?z), respectively.

The electronic structures of Ni(II) and Cu(II) bis(acetylacetonates) and some of their gamma-substituted analogues (X = Cl, Me) are studied by photoelectron spectroscopy (PES). The vertical ionization energies of the compounds are determined, and the spectra are interpreted based on the trends of changes in the electronic structure and photoelectron spectra of acetylacetonates upon gamma-substitution. The suggested interpretation of the photoelectron spectra is confirmed by the quantum chemical INDO calculations of the electronic structure of the Cu(II) compounds.

The syntheses, spectroscopic characterization (IR, 1H and 31P NMR, ESI-MS) and conductivity studies of the mixed N,P-donor complexes of copper(I) thiocyanate: [Cu(NCS)(py)2-(PPh3)], (2), [Cu(NCS)(Mepy)(PPh3)]2, (3), [Cu(NCS)(phen)- (PPh3)], (4), [Cu(NCS)(bpy)(PPh3)], (5), [Cu(NCS)(bpy)-(PPh2py)], (6), [Cu(NCS)(py)(PPh2py)], (7), (py = pyridine; Mepy = 2-methylpyridine; phen = 1,10-phenanthroline, bpy = 2,2?-bipyridyl), together with single-crystal X-ray structural characterizations of 2, 3, 4 (new polymorph), 5 and 6 are reported, which provides an opportunity to study the effect of the introduction of a pair of nitrogen donors, both unidentate and chelate, on the bonding parameters of the Cu/NCS/P system. Cu-P and Cu-N2(ar) are found to be similar [2.1974(5) and 2.091(2), 2.070(1) A for py2 adduct 2, cf. 2.1748(9)-2.200(1) and 2.071(2)-2.106(4) A for the counterpart values for bidentate adducts 4-6]. However, Cu-N(CS) and Cu-N-C are 2.013(2) A and 157.4(2) for py2 adduct 2 and 1.946(2)-1.981(8) A and 166.7(2)-176.58(2) for bidentate counterparts 4-6. The change is attributed primarily to the closure in the N-Cu-N angle [99.58(8) for py2 2; 77.7(6)-80.5(3) for N?N-bidentate donors 4-6]. In consequence of the increased steric profile of the Mepy ligand, we find the stoichiometry diminished to 1:1:1, which resulted in the formation of [(Ph3P) MepyCu(NCSSCN)Cu(Mepy)(PPh3)] dimers. TDDFT/CPCM calculations were used to clarify the type of transitions involved in the UV/Vis absorption spectra, and the corresponding experimental photoemission data were acquired. The 31P CPMAS spectra of the copper derivatives exhibit distorted quartets that afford values for 1JCu,P. Furthermore, the quadrupole-induced distortion factors were calculated, and in the cases of 2, 4 and 5, the quadrupole coupling constants were obtained, on the basis of the X-ray structures.

A variety of metal salts have been found to undergo reduction by thermal and photochemical interaction with tetraarylborate salts and with neutral alkyl- and aryl-borane complexes.In the cases of Cu2+, Cu+, Ni2+, Co2+, Pd2+, Pt2+, Ag+, Zn2+, Hg2+, Sn2+, Pb2+ and Rh3+ salts, such photochemical reductions with NaBPh4 led to the deposition of the free metal, while a number of binary mixtures of metal salts led to the codeposition of both metals, sometimes as true alloys, under such photoreduction.In the course of these reductions the arylboratereductants underwent oxidative coupling of the aryl groups to form biaryls in a strictly intra-ionic (for BAr4-) or intramolecular (Ar3B) manner respectively.Individual studies of the photochemistry of the tetraarylborate anion itself, of cuprous tetraphenylborate and of the triphenylborane-pyridine complex have adduced evidence for a gamut of reactive intermediates capable of serving as the photoreductant for metal ions, such as triarylborane radical anions, diarylborate(I) anions or arylborenes, 7-borabicycloheptadiene anions or neutral complexes and finally arylborohydride anions or arylboron hydrides.The role of these intermediates both in the photoinduced skeletal rearrangements of arylboranes and in the concomitant reduction of metal ions is discussed in critical detail.Key words: Boron; Aryl; Oxidation; Copper; Nickel; Zinc

Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. 13395-16-9, Name is Bis(acetylacetone)copper, belongs to copper-catalyst compound, is a common compound. Reference of 13395-16-9In an article, once mentioned the new application about 13395-16-9.

Liquid-phase oxidation of 3,5-di-tert-butylcatechol (3,5-DtBC) by molecular oxygen was carried out in the presence of homogeneous Cu(II) chelates or heterogeneous Cu(II)-poly(4-vinylpyridine) (Cu(II)-PVP) catalytic systems. The oxidation product in both cases is 3,5-di-tert-butyl-o-benzoquinone (3,5-DtBQ). The catalytic activity of the oxidation of 3,5-DtBC catalyzed by the homogeneous Cu(II) system was found to be affected by the Cu(II) chelates used as the catalyst, the addition of pyridine derivatives, and their amounts added. The oxidation activity was found to increase with the basicity of the added pyridine derivatives. The kinetic data obtained from the formation rate of 3,5-DtBQ by the homogeneous bis(acetylacetonato)Cu(II)-pyridine catalytic system showed that the rate was independent of the 3,5-DtBC concentration, second order in the concentration of the catalyst, and first order with respect to the partial pressure of oxygen. The homogeneous copper(II) chelate-catalyzed oxidation of 3,5-DtBC confirmed the stoichiometric equation 3,5-DtBC + 1 2O2 = 3,5-DtBQ + H2O. On the basis of these data, possible mechanistic interpretations are discussed, in which a dimeric Cu(II) complex is assumed to be the active species. The kinetics of 3,5-DtBC oxidation by molecular oxygen in the presence of the heterogeneous Cu(II)-PVP catalyst revealed that both the oxygen absorption rate and effectiveness factor decreased with increasing particle size of the Cu(II)-PVP catalyst. The increase of the particle size of the catalyst was found to cause an increase in the fraction of mass transfer resistance in the total (mass transfer + reaction) resistance of the oxidation reaction.

Attempts to build up polyanionic networks on the basis of thiocyanatometallates of Cu1 and Ag1 led to the synthesis of three new tris(thiocyanato)dimetallates(I) A[M2(SCN)3] with M = Cu, Ag and A = Me3NH and A = [Me2CNMe2]. The crystal structures show distorted tetrahedral [M(SCN)3(NCS)] and [M(SCN)2(NCS)2] building groups interlinked by SCN bridges. The resulting 3-dimensional frame works accommodate the counter cations in spacious voids. Me3NHCu2(SCN)3 (1) was synthesized by reaction of CuSCN with (CH3)3NHCl in the presence of an excess of KSCN in acetone. 1 crystallizes in the monoclinic space group P21/c with a = 578.4(1), b = 3025.1(5), c = 754.7(3) pm; beta = 112.53; Z = 4. The reaction of CuSCN or AgSCN with (CH3)2NH2Cl and KSCN in acetone resulted in the formation of [Me2CNMe2]Cu2(SCN)3 (2) and [Me2CN-Me2]Ag2(SCN)3 (3). Compound 2 crystallizes in the orthorhombic space group P212121 with a = 720.6(1), b= 1161.5(1), c = 1655.0(2) pm; Z = 4.
