Single crystal X-ray structural characterizations are recorded for a wide range of adducts of the form MX:dppx (1:1)(n), M = silver(I) (predominantly), copper(I), X = simple (pseudo-) halide or oxy-anion (the latter spanning, where accessible, perchlorate, nitrate, carboxylate – a range of increasing basicity), dppx=bis(diphenylphosphino)alkane, Ph2P(CH 2)xPPh2, x = 3-6. Adducts are defined of two binuclear forms: (i) [LM(mu-X)2L], with each ligand chelating a single metal atom, and (ii) [M(mu-X)2(mu-(P-L-P?)) 2M?] where both ligands L and halides bridge the two metal atoms; a few adducts are defined as polymers, the ligands connecting M(mu-X)2M? kernels, this motif persisting in all forms. Synthetic procedures for all adducts have been reported. All compounds have been characterized both in solution (1H, 13C, 31P NMR, ESI MS) and in the solid state (IR).

Organolead trihalide perovskite materials have attracted considerable interest because of their successful application in fabricating high-efficiency photovoltaic cells. Charge transport layers play a significant role in improving the efficiency and stability of perovskite solar cells (PSCs). In this work, we investigated the p-type doping effect of the poly(triarylamine) (PTAA) layer on the performance of PSCs by using three dopants. We observe that doping copper(I) thiocyanate (CuSCN) into PTAA led to a higher performance improvement for the PSCs than the use of copper(I) iodide (CuI) or lithium salt (Li-TFSI) as the dopant. The power conversion efficiency (PCE) of the PSCs significantly improved from 14.22% to 18.16% upon doping 2.0 wt % CuSCN with simultaneously enhanced open-circuit voltage, short-circuit current density, and fill factor. The long-term stability of the PSCs was also improved with significantly reduced PCE degradation (from 79% to 25%) after 200 h. Our results provide a simple method to improve the performance of planar PSCs by adding dopants into PTAA.

Construction of dye-sensitized solid-state solar cells requires high band-gap (therefore, transparent) hole collectors which can be deposited on a dye-coated nanocrystalline semiconductor surface without denaturing the dye. Copper (I) thiocyanate (CuSCN) is an important p-type semiconductor satisfying the above requirements. However, the conductivity of this material, which depends on excess SCN, is not sufficiently high and polymerization of SCN prevents incorporation of sufficient amount of excess SCN during the process of synthesis of CuSCN. We have found that the conductivity of solid CuSCN can be increased by exposure to halogen gases which generate SCN or to a solution of (SCN)2 in CCl4. The latter method is suitable for doping of CuSCN films in dye-sensitized solid-state solar cells.

Several mixed ligand complexes of copper(II) and nickel(II) having the compositions and , where aaH is acetylacetone, tcaH is trichloroacetic acid; L is gamma-picoline, imidazole, 2-picoline-N-oxide or thiourea and M is Cu(II) or Ni(II), have been isolated and characterised on the basis of their analyses, molar conductance, magnetic susceptibility, infrared, electronic spectral data and thermogravimetric measurements.The infrared spectra reveal the presence of uninegative bidentate acetyl acetonate and trichloroacetate groups in all these complexes.As the temperature increases, the mixed ligand complexes start decomposing with the loss of neutral donor ligand, followed by trichloroacetate ion and acetylacetonate ion in definite steps and ultimately forming MO at 600-675 deg .Square planar, tetrahedral, distorted octahedral and octahedral structures have been proposed for the complexes, , , and , respectively.

Copper(I) thiocyanate derivatives were prepared by the reaction of CuNCS with pyridine (py) and tertiary monophosphine ligands [PR3 in general; in detail: PPh3, triphenylphosphine, P(4-FPh)3, tris(4-fluorophenyl)phosphine)], as well as the potentially bidentate ligand diphenyl(2-pyridyl)phosphine (PPh2py). Mechanochemical methods were used in some cases to investigate stoichieometries that were not easily accessible by conventional solution syntheses. Three forms of the resulting adducts of CuNCS/PR3/py-base (1:3-n:n) stoichiometry-all containing four-coordinate copper(I) atoms and monodentate N-thiocyanate groups-were confirmed crystallographically. Mononuclear arrays are defined for [(PPh2py)3-n(py)nCuNCS], n = 0, 1, 2, the monodentate thiocyanate being N-coordinated in all; two polymorphs are observed for the n = 2 complex, both crystallizing in monoclinic P21 (Z = 2) cells with similar cell dimensions, but with aromatic components eclipsed about the Cu-P bond in the PPh3 complex, and staggered in the PPh2py complex. Bridging thiocyanate groups are found in the 1:1:1 CuNCS/PPh2py/2-methylpyridine (mpy) and P(4-FPh)3/mpy complexes, wherein centrosymmetric dimers with eight-membered central rings are obtained: [(R3P)(mpy)Cu(NCS)2Cu(PR3)(mpy)], as is also the case in the parent 1:2 CuNCS/PPh2py adduct [(pyPh2P)2Cu(NCS)2Cu(PPh2py)2]. For the 1:1:1 CuNCS/P(4-FPh)3/py and PPh3/Brmpy (Brmpy = 3-bromo-4-methylpyridine) adducts, and, likely, CuNCS/PPh2py/py (1:1:1), single-stranded polymers of the form [?Cu(NCS)(PR3)(py-base)(Cu)?](?|?) with linearly bridging NCS ligands were obtained. Some derivatives, representative of all forms, display medium to strong green to blue luminescence when excited with radiation at 365 nm. The 31P CPMAS NMR spectroscopic data clearly differentiate the inequivalent phosphorus positions within each system, showing a wide range of 1J(31P,63/65Cu) values ranging from 965 Hz for [Cu(NCS)(PPh2py)3] to 1540 Hz for dimeric [(4-FPh)3P(mpy)Cu(NCS)2Cu(P(4-FPh)3)(mpy)], reflecting the large variations in the Cu-P bond length.

Computed Properties of CCuNS, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects.

In this work, soluble two-dimensional (2D) material of antimonene quantum sheets (AMQSs) is used to form a bilayer hole extraction layer (HEL) with CuSCN. It proves that the application of AMQSs helps to passivate surface defects of CuSCN, resulting in diminished recombination loss and depressed exciton quenching effect, and thereby achieving improved photovoltaic performance. In OPVs based on poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b?]dithiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2-carboxylate-2-6-diyl)]: [6,6]-phenyl C71-butyric acid methyl ester (PTB7-Th:PC71BM), over 12% enhancement of power conversion efficiency (PCE) is observed compared to that of the reference cell fabricated with pure CuSCN as an HEL. The advantage of the bilayer CuSCN/AMQS HEL is also confirmed in non-fullerene systems of PBDB-T-2F:IT-4F and PTB7-Th:ITIC. In a cell based on PBDB-T-2F:IT-4F, a PCE of 10.14% was obtained after application of AMQSs, which improved by about 10% compared to that of the reference cell using pure CuSCN as an HEL. Furthermore, cells based on CuSCN and CuSCN/AMQS HEL exhibit superior air stability. The use of a bilayer CuSCN/AMQS HEL provides a promising approach to obtain efficient and stable organic solar cells.

In this work, we report the effects of NNS-thiolate ligands and nuclearity (monomer, dimer) on the stability of iron complexes related to the active site of monoiron hydrogenase (Hmd). A thermally stable iron(II) dicarbonyl motif is the core feature of the active site, but the coordination features that lead to this property have not been independently evaluated for their contributions to the {Fe(CO)2}2+ stability. As such, non-bulky and bulky benzothiazoline ligands (thiolate precursors) were synthesized and their iron(II) complexes characterized. The use of non-bulky thiolate ligands and low-temperature crystallizations result in isolation of the dimeric species [(NNS)2Fe2(CO)2(I)2] (1), [(NPhNS)2Fe2(CO)2(I)2] (2), and [(MeNNS)2Fe2(CO)2(I)2] (3), which exhibit dimerization via thiolato (mu2-S)2 bridges. In one particular case (unsubstituted NNS ligand), the pathway of decarbonylation and oxidation from 1 was crystallographically elucidated, via isolation of the half-bis-ligated monocarbonyl dimer [(NNS)3Fe2(CO)]I (4) and the fully decarbonylated and oxidized mononuclear [(NNS)2Fe]I (5). The transformations of dicarbonyl complexes (1, 2, and 3) to monocarbonyl complexes (4, 6, and 7) were monitored by UV/vis, demonstrating that 1 and 3 exhibit longer t1/2 (80 and 75 min, respectively) than 2 (30 min), which is attributed to distortion of the ligand backbone. Density functional theory calculations of isolated complexes and putative intermediates were used to corroborate the experimentally observed IR spectra. Finally, dimerization was prevented using a bulky ligand featuring a 2,6-dimethylphenyl substituent, which affords mononuclear iron dicarbonyl complex, [(NPhNSDMPh)Fe(CO)2Br] (8), identified by IR and NMR spectroscopies. The dicarbonyl complex decomposes to the decarbonylated [(NPhNSDMPh)2Fe] (9) within minutes at room temperature. Overall, the work herein demonstrates that the thiolate moiety does not impart thermal stability to the {Fe(CO)2}2+ unit formed in the active site, further indicating the importance of the organometallic Fe-C(acyl) bond in the enzyme.

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.
