    Redox properties of rhodium(III) oxo-bridged carboxylate complexes2001In: Russian journal of general chemistry, ISSN 1070-3632, E-ISSN 1608-3350, Vol. 71, no 8, p. 1186-1193Article in journal (Refereed)
    Abstract [en]

    Chemical and electrochemical oxidation of rhodium (III) oxo-bridged carboxylate complexes was studied. The chemical [with O-3 and Ce(IV) salts] or electrochemical (at potentials of 1.00-1.20 V) oxidations of the binuclear complexes [Rh-2(mu-O)(mu-O2CCH3)(2)(H2O)(6)](2+) and [Rh-2(mu-O)(mu-O2CCF3)(2)(H2O)(6)](2+) leads to the superoxo complexes [Rh-2(mu-O)(O-2(-))(mu-O2CCH3)(2)(H2O)(5)]+ and [Rh-2(mu-O)(O-2(-))(mu-O2CCF3)(2)(H2O)(5)](+) with terminal coordination of O-2(-). The trinuclcar acetate [Rh-3(mu(3)-O)(mu-O2CCH3)(6)(H2O)(3)](+), unlike its trifluoroacetate analog [Rh-3(mu(3)-O)(mu-O2CCF3)(6)(H2O)(3)](+), is oxidized only electrochemically at a potential of 1.38 V. The oxidation of [Rh-3(mu(3)-O)(mu-O2CCH3)(6)(H2O)(3)](+) is reversible and involves formation of an unstable superoxo group O-2(-) between two Rh-3(III)(mu(3)-O) cores.

    Chemical and Photochemical Water Oxidation Catalyzed by Mononuclear Ruthenium Complexes with a Negatively Charged Tridentate Ligand2010In: Chemistry - A European Journal, ISSN 0947-6539, E-ISSN 1521-3765, Vol. 16, no 15, p. 4659-4668Article in journal (Refereed)
    Abstract [en]

    Two mononuclear ruthenium complexes [RuL(pic)(3)] (1) and [RuL(bpy)(pic)] (2) (H2L = 2,6-pyridinedicarboxylic acid, pic=4-picoline, bpy = 2,2'-bipyridine) have been synthesized and fully characterized. Both complexes could promote water oxidation chemically and photochemically. Compared with other known ruthenium-based water oxidation catalysts using [Ce(NH4)(2)(NO3)(6)] (Ce-IV) as the oxidant in solution at pH 1.0, complex 1 is one of the most active catalysts yet reported with an initial rate of 0.23 turnovers(-1). Under acidic conditions, the equatorial 4-picoline in complex 1 dissociates first. In addition, ligand exchange in 1 occurs when the Rum state is reached. Based on the above observations and MS measurements of the intermediates during water oxidation by 1 using Ce-IV as oxidant, [RuL(pic)(2)(H2O)](+) is proposed as the real water oxidation catalyst.

    Abstract [en]

    The reaction of [Ru-3(III) (mu(3)-O)(mu-O2CCF3)(6)(H2O)(3)](O2CCF3) in methanol gives two solvates, [Ru3O(O2CCF3)(6)(DMSO)(3)] center dot 1/2H(2)O (I) and [Ru3O(O2CCF3)(6)(DMSO)(3)] center dot H2O (II), of a novel trinuclear mixedvalence Ru(II,III,III) trifluoroacetate complex, where two DMSO molecules are coordinated to the Ru atoms through the O atom, while the third DMSO molecule is coordinated through the S atom. According to the X-ray diffraction data, the complex can crystallize in two crystal systems: triclinic (I) (space group P (1) over bar) and monoclinic (II) (space group P2(1)/m). The unit cell parameters for I are: a = 9.354, b = 11.005, c = 20.846 angstrom, alpha = 99.10, beta = 96.38, gamma = 92.17, Z = 2; R = 7.27%; for I are: a = 9.186, b = 17.044, c = 13.091 angstrom, beta = 101.10, Z = 2; R = 14.18%.

    Crystal formation involving 1-methylbenzimidazole in iodide/triiodide electrolytes for dye-sensitized solar cells2007In: Solar Energy Materials and Solar Cells, ISSN 0927-0248, E-ISSN 1879-3398, Vol. 91, no 12, p. 1062-1065Article in journal (Refereed)
    Abstract [en]

    Nitrogen heterocyclic compounds, such as N-methylbenzimidazole (MBI), are commonly used as additives to electrolytes for dye-sensitized solar cells (DSCs), but the chemical transformation of additives in electrolyte solutions remains poorly understood. Solid crystalline compound (MBI)(6)(MBI-H+)(2)(I-)(I-3(-)) (1) was isolated from different electrolytes for DSCs containing MBI as additive. The crystal structure of I was determined by single-crystal X-ray diffraction. In the crystal structure, 1 contains neutral and protonated MBI fragments; iodide and triiodide anions form infinite chains along the crystallographic a-axis. The role of the solvent and additives in the crystallization process in electrolytes is discussed.

    Binuclear palladium(I) and platinum(I) dimers stabilized by aromatic ligands: synthesis, structural characterization and reactivity with carbon monoxide2003In: Inorganica Chimica Acta, ISSN 0020-1693, E-ISSN 1873-3255, Vol. 350, p. 449-454Article in journal (Refereed)
    Abstract [en]

    Reaction of PdCl2 with excess of GaCl3 in aromatic solvents leads to binuclear compounds of the general formula [Pd2X2(arene)(2)], where arene = C6H6, X- = GaCl7- (1); arene = C7H8, X- = GaCl4- (2). The solid-state structures of compounds 1 and 2 have been determined by X-ray crystallography. Two molecules of the arene are bound to the dipalladium unit. The compounds 1 and 2 do not react with triphenyl phosphine. Reaction of carbon monoxide with 1 in benzene solution yields [Pd-2(GaCl4)(2)(C6H6)(2)] (3), for which the crystal structure has also been determined. The compound [Pt-2(GaCl4)(2)(C10H10)(2)].2C(6)H(6) (4), which was obtained by reaction of K-2[PtCl4] with GaCl3 and naphthalene in a benzene solution, has a similar structure in the solid state.

    Abstract [en]

    The synthesis and X-ray characterization of binuclear dipalladium(I) and diplatinum(I) p-xylene complexes [Pd-2(eta(6)-C8H10)(2)(mu-Cl/Br)(2)(GaCl3)(2)] (1) and [Pt-2(eta(6)-C8H10)(2)(Ga2Br7)(2)] (5) are reported. It was established that the toluene ligands in the palladium complex [Pd-2(eta(6)-C7H8)(2)(GaCl4)(2)] (3) can be substituted by naphthalene without disruption of the metal-metal bond. The reaction of 3 with Pd(PPh3)(4) leads to the formation of a dipalladium(II) mu-diphenylphosphido compound [Pd2(mu- PPh2)(PPh3)(4)] (GaCl4)(2) center dot 4(C7H8) (4), most likely also involving a bridging mu-H ligand.

    The reaction of palladium(H) bromide or palladium(II) iodide with the respective gallium(III) halogenide in the presence of aromatic solvents leads to the formation of palladium(II) tetrabromo- and tetraiodogallate. The compounds are isostructural {monoclinic, C2/m, Pd[GaBr4](2): a=1267(2), b=808(1), c=722(1) pm, beta=94.5(1)degrees; Pd[GaI4](2): a=1363(1), b=849.9(4), c=756.6(7) pm, beta=95.38(3)degrees}. The structures contain mononuclear complexes Pd[GaX4](2), where X- = Br- (1), I- (2). The crystal structures of 1 and 2 were determined by single-crystal X-ray diffraction. Crystals of both compounds turned out to be similarly twinned.

    Arene complexes of gallium: An effective tool for the synthesis of transition metal clusters and complexes2008In: Coordination chemistry reviews, ISSN 0010-8545, E-ISSN 1873-3840, Vol. 252, no 15-17, p. 1564-1576Article in journal (Refereed)
    Abstract [en]

    In this review, the interactions between gallium(III) halides or gallium(I) subvalent halides and aromatic hydrocarbons in solution and solid state are discussed. Such unique properties of gallium halides-arene mixtures as the ability to reduce metallic centers and accept halide atoms make them very efficient tool for the preparation of low-valent clusters and complexes of transition metals. Diverse mono- and polynuclear arene complexes of d- and f-elements, including coordination polymers, may be achieved by the reactions between transition metal halides and gallium(III) halides in arene media. The role of Lewis acidity of gallium halides, the nature of the substituents on the arene ring and the nature of transition metals are discussed in terms of coordination mode of arenes and resulting structure of the transition metal-arene complexes.

    Ionic liquid electrolytes for dye-sensitized solar cells2008In: Dalton Transactions, ISSN 1477-9226, E-ISSN 1477-9234, no 20, p. 2655-2666Article in journal (Refereed)
    Abstract [en]

    The potential of room-temperature molten salts (ionic liquids) as solvents for electrolytes for dye-sensitized solar cells has been investigated during the last decade. The non-volatility, good solvent properties and high electrochemical stability of ionic liquids make them attractive solvents in contrast to volatile organic solvents. Despite this, the relatively high viscosity of ionic liquids leads to mass-transport limitations. Here we review recent developments in the application of different ionic liquids as solvents or components of liquid and quasi-solid electrolytes for dye-sensitized solar cells.

    Electrolytes for dye-sensitized solar cells based on interhalogen ionic salts and liquids2007In: Inorganic Chemistry, ISSN 0020-1669, E-ISSN 1520-510X, Vol. 46, no 9, p. 3566-3575Article in journal (Refereed)
    Abstract [en]

    In this paper, we report on the preparation of interhalogen ionic liquids of the general formula [K+]XY2-, where K+ = 1,3-dialkylimidazolium, 1,2,3-trialkylimidazolium, or N-alkylpyridinium; XY2- = IBr2- or I2Br-. These compounds were characterized in solution and the solid state by NMR, IR, Raman, and mass spectroscopy. The crystal structure of the compound [Me(2)BuIm]IBr2 (7) shows that the IBr2- anion has a linear Br-I-Br structure. Indications of an equilibrium between different forms of XY2- anions in solution are observed. Interhalogen ionic salts and liquids were used as electrolyte components for encapsulated monolithic dye-sensitized solar cells. Overall light-to-electricity conversion efficiencies up to 6.4%, 5.0%, and 2.4% at 1000 W/m(2) were achieved by using electrolytes based on interhalogen ionic salts and gamma-butyrolactone, glutaronitrile, or native ionic liquids as solvents, respectively. Moreover, in terms of stability, the cell performance lost 9-14% of the initial performance after 1000 h illumination at 350 W/m(2).

    Syntheses and crystal structures of new palladium(II) and platinum(IV) trialkylsulfonium compounds2007In: Zeitschrift für Anorganische und Allgemeines Chemie, ISSN 0044-2313, E-ISSN 1521-3749, Vol. 633, no 4, p. 643-646Article in journal (Refereed)
    Abstract [en]

    The reactions of platinum(II) iodide with triethyl- or trimethylsulfonium iodide in acetonitrile solution lead to the formation of crystalline products (Et3S)(2)[PtI6] (1) and [Me3S]=[PtI6]center dot CH3CN (2), respectively. The formation of Pt(IV) complexes may be explained either by disproportionation of PtI2 or oxidation by oxygen. Palladium(II) iodide reacts with triethylsulfonium iodide to give the palladium(II) complex (Et3S)(2)[PdI4] (3). The crystal structures of 1-3 were determined by single-crystal X-ray diffraction. In the crystal structures, the compounds 2 and 3 exhibit an extensive hydrogen-bonding network.

    On the correlation between dye coverage and photoelectrochemical performance in dye-sensitized solar cells2014In: Physical Chemistry, Chemical Physics - PCCP, ISSN 1463-9076, E-ISSN 1463-9084, Vol. 16, no 2, p. 711-718Article in journal (Refereed)
    Abstract [en]

    Concentration depth profiles of the ruthenium based dyes Z907 and N719 adsorbed onto titania are measured directly and used for determining the adsorption isotherm of the dyes. Dye layers formed by both grow in islands on the titania which do not cover the entire titania surface even at the maximum coverage. Impedance spectroscopy in conjunction with the adsorption isotherms shows that recombination losses mainly appear between the dye and the electrolyte solution. The short circuit current and the efficiency increase linearly with the dye coverage. The open circuit voltage slightly increases with increasing dye coverage which is interpreted as most likely to be a consequence of the higher charge in the particles upon higher dye loading on the TiO2 surface.

    Abstract [en]

    Norway spruce wood was mechanically pulverized to varying degrees. The solubility of the wood samples, in a range of common ionic and molecular solvents, was quantified using a novel P-31 NMR technique. The results show that intact wood is not soluble under mild treatment conditions, in cellulose-dissolving or swelling solvents.

    Abstract [en]

    A way to achieve a high-efficiency dye-sensitized solar cell is to combine an n-type TiO2-based photoanode with a p-type photocathode in a tandem configuration. The development of an efficient photocathode is, at present, the key target. We have optimized the NiO, I-3(-)/I- p-DSSC system to obtain record photocurrent, giving 64% incident photon-to-current conversion efficiency (IPCE) and 5.48 mAcm(-2) J(SC).

    The monolithic multicell: A tool for testing material components in dye-sensitized solar cells2007In: Progress in Photovoltaics, ISSN 1062-7995, E-ISSN 1099-159X, Vol. 15, no 2, p. 113-121Article in journal (Refereed)
    Abstract [en]

    A multicell is presented as a tool for testing material components in encapsulated dye-sensitized solar cells. The multicell is based on a four-layer monolithic cell structure and an industrial process technology. Each multicell plate includes 24 individual well-encapsulated cells. A sulfur lamp corrected to the solar spectrum has been used to characterize the cells. Efficiencies up to 6.8% at a light-intensity of 1000 W/m(2) (up to 7.5% at 250 W/m(2)) have been obtained with an electrolyte solution based on gamma-butyrolactone. Additionally, a promising long-term stability at cell efficiencies close to 5% at 1000 W/m(2) has been obtained with an electrolyte based on glutaronitrile. The reproducibility of the cell performance before and after exposure to accelerated testing has been high. This means that the multicell can be used as an efficient tool for comparative performance and stability tests.

    Parallel-connected monolithic dye-sensitised solar modules2010In: Progress in Photovoltaics, ISSN 1062-7995, E-ISSN 1099-159X, Vol. 18, no 5, p. 340-345Article in journal (Refereed)
    Abstract [en]

    Light-soaking and high-temperature storage testing of monolithic dye-sensitised solar modules with total area module efficiencies above 5% have been performed. Our experiences from the development of a four-layer monolithic dye-sensitised solar test cell for comparative testing of material components for dye-sensitised solar cells have directed our module development to a novel device design consisting of parallel-connection of individual monolithic cells. The results from the accelerated testing of the modules (total area of 17.0 cm(2)) with four parallel-connected cells (active area of 3.38 cm(2)/cell) are equivalent to those obtained for the monolithic single test cells when using identical device components. The successful transfer from cell to module stability is an important milestone in our ambition to develop a low-cost Photovoltaic (PV) technology. Moreover, our results indicate that intensified research and development to define the procedures for relevant accelerated testing of dye-sensitised solar modules is urgently required.

    Microwave assisted synthesis of ZnS quantum dots using ionic liquids2012In: Materials letters (General ed.), ISSN 0167-577X, E-ISSN 1873-4979, Vol. 89, p. 316-319Article in journal (Refereed)
    Abstract [en]

    In this work we report results from microwave (MW) assisted synthesis of highly crystalline ZnS quantum dots (QDs) using ionic liquid (ILs) as MW absorbing medium. Two types of ionic liquids, imidazolium and phosphonium based, were used. The QDs are less than 5 nm in size and of wurtzite ZnS type, as characterized by high-resolution transmission electron microscopy (HR-TEM) and selected area electron diffraction (SAED) pattern. The optical properties were investigated by UV-vis absorption and show a blue shift in absorption as compared to bulk wurtzite ZnS due to quantum confinement effects. The photoluminescence (PL) spectra of the QDs show different trap state emissions.

These compounds represent examples of crystal engineering, employing a simple strategy of synthesis. The two series are related, and the capacity to incorporate polyiodide ions dependent on the length of the hydrocarbon chains is indicated.

    Light-driven hydrogen production catalysed by transition metal complexes in homogeneous systems2009In: Dalton Transactions, ISSN 1477-9226, E-ISSN 1477-9234, no 33, p. 6458-6467Article in journal (Refereed)
    Abstract [en]

    The development of heterogeneous catalytic systems for hydrogen production from water under light irradiation has been investigated during last three decades. Homogeneous photocatalysts, however, are very attractive in sense that their chemical and photochemical properties can be understood and tuned on molecular level. Moreover, in homogeneous systems catalysts may be covalently bound to photosensitizers, which leads to more efficient electron transfer. Molecular devices for water splitting based on such a systems are of great interest. In this review, we summarize recent progresses in the synthesis, properties and application of metal-based molecular catalysts for photoinduced hydrogen evolution in homogeneous systems.

    Synergistic Effect of N-Methylbenzimidazole and Guanidinium Thiocyanate on the Performance of Dye-Sensitized Solar Cells Based on Ionic Liquid Electrolytes2010In: The Journal of Physical Chemistry C, ISSN 1932-7447, E-ISSN 1932-7455, Vol. 114, no 50, p. 22330-22337Article in journal (Refereed)
    Abstract [en]

    The effects of additives guanidinium thiocyanate (GSCN) and N-methylbenzimidazole (MBI) on the photovoltaic performance of dye-sensitized solar cells based on low-viscous, binary ionic liquid and organic liquid electrolytes were investigated. Addition of only GSCN to the electrolyte has a pronounced influence on the short-circuit current, owing largely to the positive shift of the conduction band edge potential, probably increasing the injection efficiency of the excited dye. When only MBI was added to the electrolyte, a significant improvement of the open-circuit voltage was found, which could be attributed to a negative shift of the TiO2 conduction band edge potential and a longer electron lifetime under open-circuit conditions. Synergistic effects were observed when GSCN and MBI were used together in the ionic liquid-based electrolyte. In this case, optimal open-circuit voltage and total conversion efficiency were obtained among the ionic liquid electrolytes studied mainly due to the more efficient retardation of the recombination loss reaction at the TiO2/electrolyte interface.

    Investigation of Iodine Concentration Effects in Electrolytes for Dye-Sensitized Solar Cells2010In: The Journal of Physical Chemistry C, ISSN 1932-7447, E-ISSN 1932-7455, Vol. 114, no 23, p. 10612-10620Article in journal (Refereed)
    Abstract [en]

    The present work describes the effects of different iodine concentrations and iodine-to-iodide ratios in electrolytes for dye-sensitized solar cells based on low-viscous, binary ionic liquid and organic liquid solvents. Current-voltage characteristics, photoelectrochemical measurements, electrochemical impedance spectroscopy, and Raman spectroscopy were used for characterization. Optimal short-circuit current and overall conversion efficiency were achieved using intermediate and low iodine concentration in ionic liquid-based and acetonitrile-based electrolytes, respectively. Results from photoelectrochemical and Raman-spectroscopic measurements reveal that both triiodide mobility and chemical availability affect the optimal iodine concentration required in these two types of electrolytes. The higher iodine concentrations required for the ionic liquid-based electrolytes partly compensate for these effects, although negative effects from higher recombination losses and light absorption of iodine-containing species start to become significant.

    Tetrathiafulvalene as a one-electron iodine-free organic redox mediator in electrolytes for dye-sensitized solar cells2012In: RSC Advances, ISSN 2046-2069, Vol. 2, no 3, p. 1083-1087Article in journal (Refereed)
    Abstract [en]

    Tetrathiafulvalene (TTF) was investigated as an organic iodine-free redox mediator in electrolytes for dye-sensitized, nanocrystalline solar cells (DSCs) and was compared to the commonly used iodide/triiodide system. The TTF system studied was determined to be a one-electron transfer system, although potentially exhibiting three well-defined oxidation states. Despite the slightly positive redox potential of TTF, electrolytes with TTF displayed around 200 mV lower open-circuit voltage than the iodide/triiodide system. This can mainly be ascribed to a much shorter electron lifetime in the TiO2 film. Mass transport limitations for redox species in TTF-based electrolytes were found to be serious. Electrochemical impedance measurements (EIS) show that the charge-transfer resistance at the counter electrode in the electrolyte with TTF is considerably larger than for the iodide/triiodide system. In addition, the light absorption of the TTF-based electrolyte is stronger than that for the iodide/triiodide system. Thus, DSCs with TTF-based electrolytes show worse photovoltaic performance than those with iodide/triiodide-based electrolytes. The differences in IV characteristics and charge-recombination behavior have also been elucidated.

    Room-Temperature Synthesis of the Bi-5[GaCl4](3) Salt From Three Different Classes of Ionic Liquids2013In: Journal of cluster science, ISSN 1040-7278, E-ISSN 1572-8862, Vol. 24, no 1, p. 157-164Article in journal (Refereed)
    Abstract [en]

    Following the development in the synthesis of subvalent cluster compounds, we report on the use of three different classes of room-temperature ionic liquids for the synthesis of the pentabismuth-tris(tetragallate) salt, Bi-5[GaCl4](3), characterized by X-ray diffraction. The Bi-5[GaCl4](3) salt was prepared by reduction of BiCl3 using gallium metal in ionic liquid reaction media containing a strong Lewis acid, GaCl3. The ionic liquids; trihexyltetradecyl phosphonium chloride [Th-Td-P+]Cl-, 1-dodecyl-3-methylimidazolium chloride [Dod-Me-Im(+)]Cl- and N-butyl-N-methylpyrrolidinium chloride [Bu-Me-Pyrr(+)]Cl- from three of the main classes of ionic liquids were used in synthesis. Reactions using ionic liquids composed of the trihexyltetradecyl phosphonium cation [Th-Td-P+] and the anions; tetrafluoroborate [BF4 (-)], bis(trifluoro-methyl sulfonyl) imide [(Tf)(2)N-] and hexafluorophosphate [PF6 (-)] were also investigated.
