Intensification of slow reversible chemical transformation: carboxylation of resorcinol as a case study

Lioubov Kiwi, Charline Berguerand, Anne-Laure Dessimoz

Conjugated kinetic and thermodynamic modeling is suggested as a suitable approach to identify a novel process window (NPW) for the intensification of slow reversible reactions. The aqueous Kolbe-Schmitt synthesis of beta-resorcylic acid is taken as a model ...

Measured binding coefficients for iodine and ruthenium dyes; implications for recombination in dye sensitised solar cells

Shaik Mohammed Zakeeruddin, Robin Humphry-Baker, Filippo de Angelis, Xiong Li

We have measured the binding coefficients of iodine to three dyes used in Dye Sensitised Solar Cells (DSSCs). Binding coefficients are quantified via the effect of iodine binding on the UV-vis spectrum of the dye. From iodine titration curves of dye sensit ...

A versatile precursor for non-aqueous neptunyl(V) chemistry

Marinella Mazzanti

The polymeric complex [(NpO2Py5)(KI 2Py2)]n is prepared from dry "NpO 2Cl" by anion exchange with potassium iodide in pyridine affording the first convenient starting material for the development of NpO 2+ coordination chemistry in anhydrous organic media. ...

Extraordinarily efficient conduction in a redox-active ionic liquid

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jan Cornelius Brauer, Guido Rothenberger, Verner Thorsmolle

Iodine added to iodide-based ionic liquids leads to extraordi- narily efficient charge transport, vastly exceeding that expect- ed for such viscous systems. Using terahertz time-domain spectroscopy, in conjunction with dc conductivity, diffusivity and visc ...

Rotational Motion in LiBH4/LiI Solid Solutions

Pascal Martelli

We investigated the localized rotational diffusion of the (BH 4)- anions in LiBH4/LiI solid solutions by means of quasielastic and inelastic neutron scattering. The (BH 4)- motions are thermally activated and characterized by activation energies in the ord ...

A new family of substituted triethoxysilyl iodides as organic iodide sources for dye-sensitised solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mingkui Wang

This paper reports the synthesis and characterisation of a family of heterocyclic triethoxysilyl iodides of general formula, (EtO)(3)SiR2-(N+R1), where R-1 = -C5H11, -CH2C6H5 or -C16H33; N+ = pyrrolidinium or piperidinium; and R-2 = -(CH2)(3)- and -(CH2)(1 ...
