Effect of Coordination Sphere Geometry of Copper Redox Mediators on Regeneration and Recombination Behavior in Dye-Sensitized Solar Cell Applications

Shaik Mohammed Zakeeruddin, Yasemin Saygili, Jacques-Edouard Moser, Ulf Anders Hagfeldt, Joël Teuscher, Fabrizio Giordano, Marina Freitag, Marko Stojanovic, Jan Tiepelt

The recombination of injected electrons with oxidized redox species and regeneration behavior of copper redox mediators are investigated for four copper complexes, [Cu(dmby)2]2+/1+ (dmby = 6,6′-dimethyl-2,2′- bipyridine), [Cu(tmby)2]2+/1+ (tmby = 4,4′,6,6′ ...

Polyimidazolium Salts: Robust Catalysts for the Cycloaddition of Carbon Dioxide into Carbonates in Solvent-Free Conditions

Paul Joseph Dyson, Zhaofu Fei, Felix Daniel Bobbink, Wei Zhong

There is a growing interest in sustainable heterogeneous catalysts based on organic polymers. Here, we describe a series of polyimidazolium salt catalysts, prepared from the direct reaction of arene- bridged bis- and tris-alkyl halides with trimethylsilyli ...

Cyclic Hypervalent Iodine Reagents for Atom-Transfer Reactions: Beyond Trifluoromethylation

Jérôme Waser, Durga Prasada Rao Hari, Yifan Li, Maria Victoria Vita

Hypervalent iodine compounds are privileged reagents in organic synthesis because of their exceptional reactivity. Among these compounds, cyclic derivatives stand apart because of their enhanced stability. They have been widely used as oxidants, but their ...

Design strategy for controlled natural aging in Al-Mg-Si alloys

William Curtin

This study presents a design strategy for Al-Mg-Si alloys to control natural aging. Recently, trace addition of Sn was shown to suppress natural aging for up to two weeks, which was explained by the strong trapping of vacancies to Sn atoms. Here we explore ...

Fully inkjet printed SnO2 gas sensor on plastic substrate

Nico de Rooij, Danick Briand, El Hadji Malick Camara, Mathilde Rieu

A tin dioxide (SnO2) sensor was fabricated by inkjet printing onto polyimide foil. Gold electrodes and heater were printed on each side of the substrate. A SnO2 based ink was developed by sol-gel method and jetted onto the electrodes. A final annealing at ...

Supramolecular assemblies of organotin(IV)-diphosphoryl adducts: insights from X-rays and DFT

Kurt Schenk

Mono-, di- and tri-phenyltin(IV) adducts containing a neutral diphosphoryl ligand, Ph2P(O)OC6H4OP(O) Ph-2, were synthesized and characterized. These 2 : 1 adducts of two trans-organotin(IV) moieties and the bridging ligand all crystallize around a centre o ...

The Cause for Tremendous Acceleration of Chloride Substitution via Base Catalysis in the Chloro Pentaammine Cobalt(III) Ion

François Rotzinger, Basile Curchod

The base hydrolysis reaction of Co(NH3)5Cl2+ was investigated using density functional theory and molecular orbital methods. Geometries and energies of conjugate bases, intermediates, transition states, and minimum energy crossing points were computed. For ...

Di-n-butyltin(IV)-catalyzed dimethyl carbonate synthesis from carbon dioxide and methanol: An in situ high pressure 119Sn{1H} NMR spectroscopic study

Gabor Laurenczy

The reactivity of five di-n-butyltin(IV) complexes, n-Bu2Sn(OR)(2) (1), n-Bu2SnO (3), n-Bu2Sn(OR)O (4), (n-Bu2SnO)(2)(CO2) (6) and (n-Bu2SnO)(6)(n-Bu2SnOR)(2)(CO3) (7) (R = CH3), with CO2, suggested as possible catalyst precursors and key-interme ...

Rationalization of the inhibition activity of structurally related organometallic compounds against the drug target cathepsin B by DFT

Paul Joseph Dyson, Angela Casini, Fabio Edafe

A series of organometallic compds. of general formula [(arene)M(PTA)nXm]Y (arene = η6-C10H14, η-C5Me5); (M = Ru(II), Os(II), Rh(III) and Ir(III); X = Cl, mPTA; Y = OTf, PF6) have been screened for their cytotoxicity and ability to inhibit cathepsin B in vi ...

Chasing an Elusive Alkoxide: Attempts to Synthesize [OC(tBu)(CF3)2]−

Rosario Scopelliti, Lutz Müller

The synthesis of the alkoxide [OC(tBu)(CF3)2]− by the reaction of tBuM-reagents (M = Li; MgX) with hexafluoroacetone was attempted. This alkoxide was anticipated to be a good building block for novel weakly coordinating anions. However, in all attempted sy ...
