Superacidic or not…? Synthesis, characterisation, and acidity of the room-temperature ionic liquid [C(CH3)3]+  [Al2Br7]-.

Chemistry (Weinheim an der Bergstrasse, Germany)

Scholz F, Himmel D, Scherer H, Krossing I.
PMID: 23180742
Chemistry. 2013 Jan 02;19(1):109-16. doi: 10.1002/chem.201203260. Epub 2012 Nov 23.

The room-temperature ionic liquid (RT-IL) [C(CH(3))(3)](+)[Al(2)Br(7)](-) (m.p. 2 °C) was generated by bromide abstraction from tert-butyl bromide with the Lewis acid aluminum bromide in the absence of solvent. The crystal structure of the tert-butyl cation salt was determined by...

Stelzenmüller V, Coll M, Mazaris AD, Giakoumi S, Katsanevakis S, Portman ME, Degen R, Mackelworth P, Gimpel A, Albano PG, Almpanidou V, Claudet J, Essl F, Evagelopoulos T, Heymans JJ, Genov T, Kark S, Micheli F, Pennino MG, Rilov G, Rumes B, Steenbeek J, Ojaveer H.
PMID: 28892857
Sci Total Environ. 2018 Jan 15;612:1132-1140. doi: 10.1016/j.scitotenv.2017.08.289. Epub 2017 Sep 08.

Marine ecosystems are increasingly threatened by the cumulative effects of multiple human pressures. Cumulative effect assessments (CEAs) are needed to inform environmental policy and guide ecosystem-based management. Yet, CEAs are inherently complex and seldom linked to real-world management processes....

Photoinduced electron transfer (PET) versus excimer formation in supramolecular p/n-heterojunctions of perylene bisimide dyes and implications for organic photovoltaics.

Faraday discussions

Foldamer systems comprised of two perylene bisimide (PBI) dyes attached to the conjugated backbones of 1,2-bis(phenylethynyl)benzene and phenylethynyl-bis(phenylene)indane, respectively, were synthesized and investigated with regard to their solvent-dependent properties. UV/Vis absorption and steady-state fluorescence spectra show that both foldamers...

Unified pH values of liquid chromatography mobile phases.

Analytical chemistry

Suu A, Jalukse L, Liigand J, Kruve A, Himmel D, Krossing I, Rosés M, Leito I.
PMID: 25664372
Anal Chem. 2015 Mar 03;87(5):2623-30. doi: 10.1021/ac504692m. Epub 2015 Feb 23.

This work introduces a conceptually new approach of measuring pH of mixed-solvent liquid chromatography (LC) mobile phases. Mobile phase pH is very important in LC, but its correct measurement is not straightforward, and all commonly used approaches have deficiencies....

From unsuccessful H2-activation with FLPs containing B(Ohfip)3 to a systematic evaluation of the Lewis acidity of 33 Lewis acids based on fluoride, chloride, hydride and methyl ion affinities.

Dalton transactions (Cambridge, England : 2003)

Böhrer H, Trapp N, Himmel D, Schleep M, Krossing I.
PMID: 25803574
Dalton Trans. 2015 Apr 28;44(16):7489-99. doi: 10.1039/c4dt02822h.

The possibility of obtaining frustrated Lewis pairs (FLPs) suitable for H2-activation based on the Lewis acid B(Ohfip)3 1 (Ohfip = OC(H)(CF3)2) was investigated. In this context, the crystal structure of 1 as well as the crystal structure of the...

The Acidity of the HBr/AlBr3 System: Stabilization of Crystalline Protonated Arenes and Their Acidity in Bromoaluminate Ionic Liquids.

Chemistry (Weinheim an der Bergstrasse, Germany)

Chemistry. 2015 May 11;21(20):7489-502. doi: 10.1002/chem.201405952. Epub 2015 Mar 25.

Bulk protonated mesitylene, toluene, and benzene bromoaluminate salts were stabilized and characterized in the superacidic system HBr/n AlBr3 with NMR spectroscopy and X-ray analysis of [HC6 H3 (CH3 )3 ](+) [AlBr4 ](-) (1), [HC6 H5 (CH3 )](+) [AlBr4 ](-)...

Direct Observation of Excimer-Mediated Intramolecular Electron Transfer in a Cofacially-Stacked Perylene Bisimide Pair.

Journal of the American Chemical Society

Sung J, Nowak-Król A, Schlosser F, Fimmel B, Kim W, Kim D, Würthner F.

J Am Chem Soc. 2016 Jul 27;138(29):9029-32. doi: 10.1021/jacs.6b04591. Epub 2016 Jul 19.

We have elucidated excimer-mediated intramolecular electron transfer in cofacially stacked PBIs tethered by two phenylene-butadiynylene loops. The electron transfer between energetically equivalent PBIs is revealed by the simultaneous observation of the PBI radical anion and cation bands in the...

Coordination Chemistry of Diiodine and Implications for the Oxidation Capacity of the Synergistic Ag(+) /X2 (X=Cl, Br, I) System.

Angewandte Chemie (International ed. in English)

PMID: 27411163
Angew Chem Int Ed Engl. 2016 Aug 01;55(32):9262-6. doi: 10.1002/anie.201603913. Epub 2016 Jul 13.

The synergistic Ag(+) /X2 system (X=Cl, Br, I) is a very strong, but ill-defined oxidant-more powerful than X2 or Ag(+) alone. Intermediates for its action may include [Agm (X2 )n ](m+) complexes. Here, we report on an unexpectedly variable...
