A hydrogen bond accepting (HBA) scale for anions, including room temperature ionic liquids
Ralf Lungwitz,Stefan Spange +1 more
TL;DR: A hydrogen bond accepting (HBA) ability scale for anions of room temperature ionic liquids (RTILs) has been determined by means of 1H NMR spectroscopy and a solvatochromic UV/vis probe as mentioned in this paper.
Journal ArticleDOI
Acylhydrazones as Reversible Covalent Crosslinkers for Self‐Healing Polymers
Natascha Kuhl,Stefan Bode,Ranjita K. Bose,Jürgen Vitz,Andreas Seifert,Stephanie Hoeppener,Santiago J. Garcia,Stefan Spange,Sybrand van der Zwaag,Martin D. Hager,Ulrich S. Schubert +10 more
TL;DR: In this paper, a self-healing polymer network is obtained by a bulk polymerization of an acylhydrazone crosslinker and commercially available methacrylates as comonomers to fine-tune the Tg of the systems.
Journal ArticleDOI
Carbon-Based Anodes for Lithium Sulfur Full Cells with High Cycle Stability
Jan Brückner,Sören Thieme,Falko Böttger-Hiller,Ingolf Bauer,Hannah Tamara Grossmann,Patrick Strubel,Holger Althues,Stefan Spange,Stefan Kaskel,Stefan Kaskel +9 more
TL;DR: In this article, a balanced and stable lithium sulfur full-cell was demonstrated with silicon-carbon as well as all-carbon anodes, with a specific capacity up to 1470 mAh g−1 sulfur (720 mAhg−1 cathode), and a coulombic efficiency of over 99% even with a low amount of electrolyte.
Journal ArticleDOI
New aspects on the hydrogen bond donor (HBD) strength of 1-butyl-3-methylimidazolium room temperature ionic liquids
TL;DR: Improved hydrogen bond donor (HBD) strength parameters of 1-butyl-3methylimidazolium room temperature ionic liquids (RTILs), acceptor number (AN) of Gutmann and α of Kamlet-Taft, have been determined using [Fe(phen)2(CN)2]ClO4 as an original solvatochromic probe as discussed by the authors.
Journal ArticleDOI
The dipolarity/polarisability of 1-alkyl-3-methylimidazolium ionic liquids as function of anion structure and the alkyl chain length
TL;DR: In this paper, the influence of both cation and anion structure on π*, α, β, and π* values of 38 1-alkyl-3-methylimidazolium ILs ([Rmim]X) are presented in order to give a solid background for the discussion.
