Copper(II) and nickel(II) complexes of binucleating macrocyclic bis(disulfide)tetramine ligands

Novel macrocyclic bis(disulfide)tetramine ligands and several Cu(II) and Ni(II) complexes of them with additional ligands have been synthesized by the oxidative coupling of linear tetradentate N2S2 tetramines with iodine. Facile demetalation of the Ni(II) oxidation products affords the free 20-membered macrocycles meso-9 and rac-9 and the 22-membered macrocycle 16, all of which are potentially octadentate N4S4 ligands. X-ray structure analyses reveal distinctly different conformations for the two isomers of 9; meso-9 shows a stepped conformation in profile with the disulfide groups corresponding to the rise of the step, whereas rac-9 exhibits a V conformation with the disulfide groups near the vertex of the V. No metal complexes of rac-9 have been isolated. Crystallographic studies of three Cu(II) complexes reveal that depending upon the size of the macrocyclic ligand and the nature of the additional ligands (I-, NCO-, and CH3CN), the Cu(II) coordination geometry shows considerable variation (plasticity), with substantial changes in the Cu(II)-disulfide bonding. Thus, a diiodide salt contains six-coordinate Cu(II) to which all four bridging disulfide sulfur atoms form strong equatorial bonds. In contrast, isocyanato complexes of the 20- and 22-membered macrocycles exhibit trigonal-bipyramidal Cu(II) and distorted cis-octahedral Cu(II) geometries, respectively, having only one and no short equatorially bound sulfur atoms. The coordination geometry of the latter complex can also be described as four-coordinate seesaw with two semicoordinated S(disulfide) ligands. Disulfide ? Cu(II) ligand-to-metal charge transfer absorptions of both isocyanato-containing Cu(II) species appear too weak to observe, probably because of poor overlap of the sulfur orbitals with the Cu(II) d-vacancy. The dual disulfide-bridged Ni(II) units of the crystallographically characterized octahedral Ni(II) complex of meso-9 with axial iodide and acetonitrile ligands promote substantial antiferromagnetic coupling (J = -13.0-(2) cm-1).

A comparative study of interface engineering with different hole transport materials for high-performance perovskite solar cells

In recent years, perovskite solar cells (PSCs) are performing remarkably with efficiency more than 20%. Performance can further be improved by controlling charge transfer and recombination at electron transport material (ETM)/absorber and absorber/hole transport material (HTM) interfaces which ultimately define conduction band offset (CBO) and valence band offset (VBO). Therefore, it is worthwhile to investigate optimum band offset to get efficient PSCs. Spiro-MeOTAD is organic HTM commonly used in PSCs while CuI, CuSCN and Cu2O are inorganic HTMs which may replace spiro-MeOTAD due to their low cost and stability. In this paper, device simulation approach is used to analyze the effect of CBO, VBO and interface defect density (Nt) on the performance of PSCs for spiro-MeOTAD as organic HTM and its detailed comparison is made with Cu-based inorganic HTMs to get better insight about the best inorganic HTM. The device simulation shows that CuI has the best PCE of 22.69% when CBO and VBO is set to be +0.2 eV and 0 eV respectively at Nt of 1 × 1015 cm?3. The results indicate that Cu-based inorganic HTMs are efficient as well as stable HTMs and can be used towards commercializing the PSCs.

The Cu(I) thiocyanate complexes with N-allylquinolinium: Synthesis and crystal structures of [C9H7NC3H 5]Cu(SCN)2 and [C9H7NC 3H5]Cu2(SCN)3

The crystals of [C9H7NC3H 5]Cu(SCN)2 (I) and [C9H7NC 3H5]Cu2(SCN)3 (II) were obtained in the reaction of N-allylquinolinium bromide with CuSCN and NH4SCN in a methanol solution. The crystals of I are triclinic: space group P1, Z = 2, a = 8.619(2), b = 8.755(2), c = 10.463(3) A, alpha = 77.18(3), beta = 69.95(3), gamma = 79.38(3), V = 718.1(3) A3. The crystals of II are opthorhombic: space group P212 121, Z = 4, a = 5.744(2), b = 16.799(4), c = 17.980(5), V = 1735.9(9) A3. The structure of compound I is built of infinite linear {Cu(SCN)2-}? anions and the N-allylquinolinium cations bonded additionally by relatively weak hydrogen contacts C-H…S. The [C9H7NC3H 5]+ cations are located between the corrugated layers of the {Cu2(SCN)3-}? anions in compound II. As in the case of the previously studied copper(I) halide complexes, the C=C bond of the allyl group in the N-allylquinolinium cation of complexes I, II does not interact with Cu(I).

Effect of metal oxidation state on FRET: A Cu(i) silent but selectively Cu(ii) responsive fluorescent reporter and its bioimaging applications

Copper(ii) and copper(i) complexes of a newly designed and crystallographically characterized Schiff base (HL) derived from rhodamine hydrazide and cinnamaldehyde were isolated in pure form formulated as [Cu(L)(NO3)] (L-Cu) (1) and [Cu(HL)(CH3CN)(H2O)]ClO4 (HL-Cu) (2), and characterized by physicochemical and spectroscopic tools. Interestingly, complex 1 but not 2 offers red fluorescence in solution state, and eventually HL behaves as a Cu(ii) ions selective FRET based fluorosensor in HEPES buffer (1 mM, acetonitrile-water: 1/5, v/v) at 25 C at biological pH with almost no interference of other competitive ions. The dependency of the FRET process on the +2 oxidation state of copper has been nicely supported by exhaustive experimental studies comprising electronic, fluorimetric, NMR titration, and theoretical calculations. The sensing ability of HL has been evaluated by the LOD value towards Cu(ii) ions (83.7 nM) and short responsive time (5-10 s). Even the discrimination of copper(i) and copper(ii) has also been done using only UV-Vis spectroscopic study. The efficacy of this bio-friendly probe has been determined by employing HL to detect the intercellular distribution of Cu(ii) ions in HeLa cells by developing image under fluorescence microscope.

Accurate thermodynamic modeling of ionic liquids/metal salt mixtures: Application to carbon monoxide reactive absorption

For the first time, a theoretical semipredictive approach based on the soft-Statistical Associating Fluid Theory equation of state is presented to model the complexation reaction between carbon monoxide (CO) in a combined ionic liquid (IL) plus a copper(I) metallic salt media in terms of the gas solubility as a function of temperature, pressure, and composition. Two different degrees of molecular approximation are tested. In the first approach, the IL-metal salt mixture is treated as a single compound whose parameters are modified according to the concentration of the metallic salt. In the second approach, both compounds are treated as independent species, enhancing the predictive capability of the model. The complexation between CO molecules and the metal salt is reproduced by adding specific cross-association interaction sites that simulate the reaction. The density of the doped IL and the CO solubility are described in quantitative agreement with the experimental data at different operating conditions.
