      Cover Picture: Selenium–Selenium Bond Cleavage of Diaryl Diselenide Radical Anions During Pulse Radiolysis (ChemPlusChem 1/2015) (page 1)

      Sachiko Tojo, Dr. Mamoru Fujitsuka, Dr. Akihiko Ouchi and Prof. Dr. Tetsuro Majima

      Article first published online: 25 NOV 2014 | DOI: 10.1002/cplu.201402375

      Thumbnail image of graphical abstract

      The cover picture shows the mechanism of Se–Se σ-bond cleavage of the di-α-naphthyl diselenide radical anion (orange) to form an α-naphthylselenyl radical (dark blue) and an α-naphthylselenyl anion based on the transient absorption spectroscopic change during pulse radiolysis. An unpaired electron is initially localized in the σ* orbital of an elongated Se–Se σ-bond (orange), and then delocalized over two naphthalene rings and Se–Se bond (green) as a result of the interaction between two naphthalene π* orbitals and a Se–Se σ* orbital. Details are given in the Full Paper by Tetsuro Majima et al. on page 68.

      Back Cover: Electropolymerisation of Catalytically Active PEDOT from an Ionic Liquid on a Flexible Carbon Cloth Using a Sandwich Cell Configuration (ChemPlusChem 1/2015) (page 254)

      Muhammad E. Abdelhamid, Dr. Graeme A. Snook and Dr. Anthony P. O'Mullane

      Article first published online: 18 SEP 2014 | DOI: 10.1002/cplu.201402303

      Thumbnail image of graphical abstract

      The back cover picture shows a carbon cloth electrode being coated with the conducting polymer poly(3,4-ethylenedioxythiopene) PEDOT via an electrochemical process using a sandwich cell configuration. The cloth maintains its flexibility while ensuring a homogeneous coverage with PEDOT. The electrode is then used as an oxygen reduction catalyst which operates under both alkaline and acidic conditions while also being tolerant to the presence of methanol in the electrolyte. Details are given in the Full Paper by Anthony P. O'Mullane et al. on page 74).

      Studying ArSe: An unpaired electron of αNpSeSeαNp. is localized in the Se[BOND]Se σ* orbital with an elongated Se[BOND]Se bond at 77 K. As the temperature increases, αNpSeSeαNp. changes to Intermediate. with an absorption at longer wavelength owing to the conformational change, in which an unpaired electron is delocalized in the interaction between the π* and σ* orbital (see scheme).

      The worm turns: How does the TAT peptide translocate across a mammalian cell membrane? Three biophysical methods, which can spatially resolve scales from millimeter (quartz crystal microbalance with dissipation (QCM-D)) and micrometer (scanning electrochemical microscopy (SECM)) to nanometer (AFM), provide evidence for wormhole-like pores (see figure). The SECM image shows that these pores allow redox mediators to pass through to the sensor, but TAT disrupts bacterial-mimetic membranes.

      Subtle Differences in Initial Membrane Interactions Underpin the Selectivity of Small Antimicrobial Peptides (pages 91–96)

      Insane for the membrane: The membrane specificity of action of citropin 1.1, a 16-residue antimicrobial peptide, was studied by quartz crystal microbalance (QCM) measurements (see figure). The initial membrane interaction might determine whether the peptide transforms into the membrane-disrupting α-helical conformation. Subtle differences in the viscoelasticity measured by QCM signify the mechanistic pathway towards membrane disruption.

The conformational arrangement of P donors in the immobilized catalysts is evidenced by 31P NMR spectroscopic “through-space” coupling. Pd-catalyzed direct C[BOND]H arylation of heteroaromatics with chloroarenes illustrates the performance of these polydentate catalytic materials.

      Film library: The photoelectrochemical properties of compositions from a ternary Fe-W-O materials library strongly depend on the Fe/W ratio as well as the processing parameters. Photoelectrochemical screening was performed by using an automated optical scanning droplet cell on a continuous thin-film materials library with a controlled gradient of compositions. The maximal photocurrent was obtained from a measurement area containing 55 at % Fe (see figure).

      Rh revisited: The commonly applied in situ method for the preparation of neutral Rh complexes of the type [{Rh(PP)(μ2-X)}2] by addition of diphosphine ligand (2 equiv) to different rhodium precursors might not be as straightforward and selective as generally thought. The outcome is strongly affected by the nature of the diolefin present in the ancillary (diphosphine) ligand, the catalyst precursor, the solvent, and the temperature (see figure).

      Nanosheet arrays: Nickel-cobalt hydroxide nanosheets in the α phase and their arrays on Ni foam are synthesized with the help of 1-methyl-2-pyrrolidone. Their electrochemical properties are tuned by varying the Ni and Co contents. The bimetallic Ni–Co hydroxides exhibit much higher specific capacitances with improved rate capabilities and cycling stabilities compared with monometallic Ni hydroxide (see figure).

      Holey MOFs! Defined single-site palladium catalysts have been synthesized through postsynthetic modification (PSM) of mixed-linker metal–organic frameworks (MIXMOFs). The high porosity of the MIXMOF catalysts was retained throughout the modification process. This resulted in accessible and highly active catalytic sites for Heck-type C[BOND]C coupling reactions.

      Performance-enhanced doping: CsCl was employed as an additive to gold supported on an activated carbon (AC) catalyst, with the aim of mitigating deactivation of monometallic gold/AC caused mainly by the reduction of Au3+ at the reaction temperature of 180 °C (see figure). The prepared bimetallic Au[BOND]CsI/AC turned out to be an ideal catalyst, with not simply slightly enhanced activity, but clearly improved stability.

      Switchable electrochromism: Electrochromic symmetric and non-symmetric disubstituted oxo-bipyridinium ionic liquids are synthesised and characterised (see figure). Efficient and reversible electrochromic devices are developed through the combination of the most capable disubstituted oxo-bipyridinium ionic liquids with transparent electrolytes. These electrochromic devices may open perspectives for future applications as alternative electrochromic car rear-view mirrors and smart windows.

      An act of viologens: The study of new polymer nanoparticles that consist of viologen cavitands linked with styrene bridges is reported. The nanoparticles feature temperature-controlled binding and release of substrates, as shown by the fluorescent dye rhodamine B (see scheme). Changing the temperature from 25 to 40 °C resulted in a significant enhancement in the permeability of the nanoparticle shell for the passage of rhodamine B.

      It's terminal: Six tetrapentafluorophenylporpholactol zinc(II) complexes with β-hydrophilic chains terminated by glucosyl (neutral, ZnL1), sulfonic (anionic, ZnL2), zwitterionic (ZnL3), and quaternary ammonium groups (cationic, ZnL4–6) were synthesized and characterized (see figure). The relationship of β-ionic conjugates, cellular uptake, and intracellular photodynamic therapy activity was demonstrated and the mechanism of photoinduced cell death was studied.
