Substantial contribution of iodine to Arctic ozone destruction

Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot, Lubna Dada

Unlike bromine, the effect of iodine chemistry on the Arctic surface ozone budget is poorly constrained. We present ship-based measurements of halogen oxides in the high Arctic boundary layer from the sunlit period of March to October 2020 and show that io ...

Reactions of hypoiodous acid with model compounds and the formation of iodoform in absence/presence of permanganate

Urs von Gunten, Jun Ma

The kinetics for the reactions of hypoiodous acid (HOI) with various phenols (phenol, 4-nitrophenol, 4-hydroxybenzoic acid), 3-oxopentanedioic acid (3-OPA) and flavone were investigated in the pH range of 6.0-11.0. The apparent second order rate constants ...

A new formation strategy of hybrid perovskites via room temperature reactive polyiodide melts

Michael Graetzel, Shaik Mohammed Zakeeruddin, Andrey Petrov

Here we introduce a new solvent-free preparation method for hybrid metal halide perovskites involving the direct reaction of metallic lead with polyiodide melts. We discovered new reactive polyiodide melts (RPMs) that can be prepared simply by adding eleme ...

Influence of Elemental Iodine on Imidazolium-Based Ionic Liquids: Solution and Solid-State Effects

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Felix Daniel Bobbink, Emilia Paunescu

Ionic liquids doped with I-2, usually resulting in the formation of polyiodide anions, are extensively used as electrolytes and in iodination reactions. Herein, NMR spectroscopy and single-crystal X-ray diffraction were used to rationalize the structures o ...

Conduction Through Viscoelastic Phase in a Redox-Active Ionic Liquid at Reduced Temperatures

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jan Cornelius Brauer, Verner Thorsmolle

The phase diagram of the redox active ionic liquid 1-methyl-3-propylimidazolium iodide (PMII) is examined as a function of temperature and iodine concentration. Beyond a threshold concentration of 3.9 M, the formation of higher polyiodides gives rise to a ...

Temperature-Dependent Ordering Phenomena of a Polyiodide System in a Redox-Active Ionic Liquid

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

Iodine added to iodide-based ionic liquids leads to dramatic changes of their physical properties which may have implications for technological applications. Here we study the phase diagram of 1-methyl 3-propylimidazolium iodide, the temperature versus iod ...

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 ...

Electronic and structural evidences for charge transfer and localization in iodine-doped pentacene

Frank Nüesch, Libero Zuppiroli, Robin Humphry-Baker, Philippe Bugnon

We have investigated the doping mechanism of pentacene with iodine and its impact on the structure and on the electronic properties of single crystals, powders, and thin films in a large range of iodine concentration up to six iodine per pentacene (PEN) mo ...
