The mixture of copper(I) salts CuX (X = Cl, Br, SCN, CN, SO3CF3) and 1,10-phenanthroline (phen) reacts with 1,4-bis(diphenylphosphino)butane (dppb) to give dinuclear complexes [Cu2(dppb)(phen)2Cl2]·4DMF (1), [Cu2(dppb)(phen)2Br2]·DMF (2), [Cu2(dppb)(phen)2(SCN)2] (3) and two 1D chain complexes {[Cu2(dppb)(phen)2(CN)2(H2O)]}n·nH2O (4) and {[Cu2(dppb)(phen)2](SO3CF3)2}n (5), respectively. The structures of these compounds were investigated by elemental analysis, single-crystal X-ray diffraction, electronic absorption spectroscopy, fluorescence spectroscopy, 1H NMR and 31P NMR spectroscopy. Each Cu atom adopts a distorted tetrahedral configuration, and all the complexes are considerably air-stable in solid state and in solution. Detailed NMR studies have been performed to disclose the behavior of the prepared copper(I) complexes in solution. All the five complexes are bright green and cyan luminophores in a solid state at room temperature. This makes them potential candidates as cheap emitting materials for electroluminescent devices.

CuSCN thin films (optimized previously for perovskite photovoltaics) are deposited on glass, F:SnO2 (FTO), Au, glass-like carbon (GC), and reduced graphene oxide (rGO). They exhibit capacitive charging in an electrochemical window from ca. -0.3 to 0.2 V vs Ag/AgCl. Outside this window, CuSCN film is prone to chemical and structural changes. Anodic breakdown (at ca. 0.5 V) causes restructuring into submicrometer particles and denuding of the substrate. The natural p-doping is demonstrated by both the Hall effect and Mott-Schottky plots from electrochemical impedance. The corresponding flatband potentials (in V vs Ag/AgCl) varied with the substrate type as follows: 0.12 V (CuSCN@FTO), 0.08 V (CuSCN@Au), -0.02 V (CuSCN@GC), and 0.00 V (CuSCN@rGO). The acceptor concentrations determined from electrochemical impedance spectroscopy are by orders of magnitude larger than those from electrical conductivity and the Hall effect, the latter being regarded correct. Raman spectra confirm that thiocyanate is the dominating structural motif over the isomeric isothiocyanate. In situ Raman spectroelectrochemistry discloses substrate-specific intensity changes upon electrochemical charging. The blocking function is tested by a newly designed redox probe, Ru(NH3)63+/2+. It not only has the appropriate redox potential for testing of the CuSCN films but also avoids complications of the standard “ferrocyanide test” which is normally used for this purpose. The perovskite solar cells exhibit better solar conversion efficiency, fill factor, and open-circuit voltage for the rGO-containing devices, which is ascribed to a larger driving force for the hole injection from CuSCN into rGO.

Imaging Raman spectroscopy is explored as a new tool for in situ studies of electrochemical systems. The technique provides a spatially resolved view of molecular species present along a focused laser line. The capabilities of our system are demonstrated using an electrodeposited thin film of CuSCN plated on a cylindrical platinum electrode. It is shown that line-imaging Raman spectroscopy is able to measure the properties of the thin film deposit while simultaneously monitoring the concentration of solution species within ? 1 mm of the surface. The Raman image presented here has a spatial resolution of ?6 mum and a spectral resolution of 24 cm-1, though neither constitutes resolution limits of the instrument.

Far infrared spectra of the surface films formed upon anodic oxidation of copper have been obtained in-situ for the first time in aqueous solution environments using a synchrotron source. The spectroelectrochemical behavior of copper was studied in NaOH and in a dilute solution of KSCN in perchlorate. The oxide film at -0.05 V vs. SCE in 0.1 M NaOH solution has been identified as Cu2O. In the passive region at 0.3 V, CuO and Cu(OH)2 appear to be present on the surface.

Copper(I) complexes are studied for various potential applications due to their luminescence properties. However, issues have been identified regarding the stability of heteroleptic compounds. As a novel strategy, we propose to modify existing copper(I) complexes by introduction of molecular bridges between the different ligands. We report the synthesis and chemical properties of the complexes of 8-(diphenylphosphanyl-oxy)quinoline (POQ), a combination of a phosphine and a N-heterocycle with CuX (X = Cl, Br, I and SCN). The photophysical properties of the materials were studied. However, all four compounds were found to be labile in solution upon contact with trace amounts of water. Two POQ complexes and the decomposition products were identified as tetraphenyldiphosphoxane complexes with single crystal X-ray diffraction. We propose a design rule to prevent this behavior in future development steps.
