      Mechanically stable polymer membranes for lithium-ion batteries consist of 1-butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl) imide (PYR14TFSI) doped with 0.2 M lithium bis(trifluoromethanesulfonyl)imide (LiTFSI).

    3. Dioxygen Activation

      Mechanistic Insights into Phenol Oxidation by a Copper(II) Complex of a Pyridine- and Amide-Containing Copolymer in an Aqueous Medium

      Vasiliki Lykourinou and Li-June Ming

      Article first published online: 7 NOV 2014 | DOI: 10.1002/ejic.201402778

      Thumbnail image of graphical abstract

      A CuII complex of a pyridine- and amide-containing copolymer catalyzes phenol hydroxylation/oxidation in aqueous methanol at pH 8.0 and 25 °C. First-order rate accelerations by factors of 4.2 × 105 and 1.4 × 105 and deuterium kinetic isotope effects of 2.8 and 1.2, respectively, were observed with and without H2O2. The results suggest that different mechanisms apply for oxidation by O2 and H2O2.

    4. Cluster Compounds

      Hydrolytic Stability and Hydrogen Peroxide Activation of Zirconium-Based Oxoclusters

      Francesco Faccioli, Matthias Bauer, Danilo Pedron, Antonio Sorarù, Mauro Carraro and Silvia Gross

      Article first published online: 6 NOV 2014 | DOI: 10.1002/ejic.201402767

      Thumbnail image of graphical abstract

      The hydrolytic stability and reactivity of Zr6 and Zr12 oxoclusters are investigated by FTIR, Raman, and extended X-ray absorption fine structure (EXAFS) spectroscopy. The clusters are stable in water at neutral pH, and peroxo complexes are detected in the presence of hydrogen peroxide. A kinetic study highlights the catalytic potential of the clusters for the oxidation of methyl p-tolyl sulfide.

    5. Water Splitting

      Synthetic Strategies for Variably Substituted Ruthenium–Imidazophenanthrolinium Complexes

      Lydia Petermann, Robert Staehle, T. David Pilz, Dieter Sorsche, Helmar Görls and Sven Rau

      Article first published online: 28 OCT 2014 | DOI: 10.1002/ejic.201402669

      Thumbnail image of graphical abstract

      Different synthetic strategies are investigated for the synthesis of variably substituted ruthenium–imidazophenanthrolinium complexes. Structural and preliminary photochemical characterizations suggest that substitution patterns can be altered without influencing the photochemical properties.

    6. Heterobimetallic Complexes

      Lithium Complexes of Asymmetric Hydrogen Tetraimido Sulfate

      Julia Matussek, Regine Herbst-Irmer and Dietmar Stalke

      Article first published online: 15 OCT 2014 | DOI: 10.1002/ejic.201402624

      Thumbnail image of graphical abstract

      Asymmetrically substituted hydrogen tetraimido sulfate ligands provide two opportunities to generate metal complexes. Firstly, the lithium metal can be exchanged in a transmetalation reaction, and secondly, the proton can be replaced by an additional substituent or another metal. This gives access to heterobimetallic complexes.

    1. Carbon Materials

      Ionic Liquid Based Approaches to Carbon Materials Synthesis

      Zai-Lai Xie and Dang Sheng Su

      Article first published online: 14 OCT 2014 | DOI: 10.1002/ejic.201402607

      Ionic liquids are currently established solvents, precursors for carbon materials, and components of carbon-based ionogels. The unique properties of ionic liquids are beneficial for the formation of unusual carbon materials or composites with homogeneous heteroatom doping (e.g., N, B, S) and controllable porosity.

      Sodium alginate/graphene oxide nanocomposite films were prepared by a solvent-casting method. We report the proof of concept that such a hybrid system can be used as the active component of a triboelectric generator. The involvement of a biodegradable polymer might introduce new applications in biodegradable/biocompatible electronics.

      Conformational changes of the TFSI anion in the protic ionic liquid C2HImTFSI have been monitored by temperature-dependent Raman spectroscopy for the bulk and nano-confined states. Phase behaviours have also been spectroscopically investigated at a range of temperatures. In the nano-confined state the cis form predominates and the enthalpic term was higher.

    2. Ionic Liquids

      Organic–Inorganic Hybrid Membranes Based on Sulfonated Poly(ether ether ketone) and Tetrabutylphosphonium Bromide Ionic Liquid for PEM Fuel Cell Applications

      Article first published online: 12 SEP 2014 | DOI: 10.1002/ejic.201402538

      Thumbnail image of graphical abstract

      Three polymorphs of tris(8-hydroxyquinoline)boron (Bq3) were obtained by high-temperature substitution reaction. Their spectral and structural properties were investigated and showed Bq3 to be a potential blue emitter. Hybrid material (HM) films B2O3/Alq3/B2O3 on a glass substrate were made by vacuum sputtering. Laser heating of the HM film resulted in an irreversible change in its photoluminescence.

    4. Surface Functionalization

      Thumbnail image of graphical abstract

      Anchoring of the Eu(TTA)3phen complex on MOCVD-grown NiO films is reported. The NiO surface was activated by means of a sputtering process and functionalized with a phosphonic linker, followed by the coordination of the Eu complex through a ligand-exchange reaction. The luminescent hybrid system has been proven to retain the optical properties of the Eu complex.

    5. Self-Healing Materials

      Thumbnail image of graphical abstract

      Octameric furfuryl-functionalized spherosilicates were used to prepare self-healing hybrid materials based on a reversible Diels–Alder reaction. Two different bismaleimides were used as dienophilic cross-linkers for the self-healing materials. The healing abilities are dictated by the nature of the cross-linker.

      The applicability of the LUMPAC software for calculations of the photoluminescence properties of metal–organic frameworks is assessed by considering three systems with a ditopic 1,4-phenylenebis(methylene)diphosphonic acid ligand and Eu3+ ions. A simple method based on the crystallographic structural subunits affords excellent agreement between the calculated and experimental photoluminescence.

      Porous nanohybrids of Mg-Al-layered double hydroxide (LDH) 2D nanosheets and polyoxometalate 0D nanoclusters are synthesized by an exfoliation–reassembling process. The resulting nanohybrid materials show promising CO2 adsorption capabilities exceeding those of pristine Mg-Al-LDH, underscoring the usefulness of the present hybridization method in optimizing gas adsorption by LDH materials.

      Thin Au films on ITO that were stepwise patterned by means of nanosecond UV laser pulses transformed into semi-regular nanoparticle arrays. The modified electrode showed enhanced activity towards ferricyanide redox systems as well as glucose, and can be considered for the production of a non-enzymatic biosensor.
