ChemPhysChem 10/2014: Special issue on electrochemical energy conversion and storage

ChemPhysChem 10/2014: Special issue on electrochemical energy conversion and storageIssue 10 is a special issue on electrochemical energy conversion and storage. It has been guest edited by H. Baltruschat, K. Rajeshwar, and Y.-K. Sun and includes 27 invited contributions in this interesting field. In a Review, N. Dupré and colleagues study the interphase evolution at two promising electrode materials for Li-ion batteries. The Minireview by L. M. Peter and K. G. Upul Wijayantha summarizes the fundamental problems and new perspectives of photoelectrochemical water splitting at semiconductor electrodes. In the Articles section, W. Schmickler et al. combine DFT and molecular dynamics to study the electrochemical adsorption of OH on Pt in alkaline solutions while S. Komaba and co-workers report on a new enzyme-based anode for biofuel cells. Finally, in the Communications section, J. M. Feliu et al. describe the synthesis and electrocatalytic properties of Pt nanoparticles prepared in a water-in-oil microemulsion.

  1. Optoelectronic and Self-assembly Properties of Porphyrin Derivatives with Click Chemistry Modification

    Liang Pengxia, Zhengcai Du, Dr. Dong Wang, Prof. Dr. Zhou Yang, Huiyun Sheng, Shuqiong Liang, Hui Cao, Wanli He and Prof. Dr. Huai Yang

    Article first published online: 22 AUG 2014 | DOI: 10.1002/cphc.201402401

    A series of functionalized porphyrin molecules containing electron-rich alkynes, synthesized by means of the Sonogashira coupling reaction, are further modified by reacting the ethynyl groups with click reagents through a formal [2+2] click reaction. Through a phase-exchange self-assembly method, highly organized morphologies are observed by scanning electron microscopy.

    Thiophene length on the BHJ: An investigation of the influence of the thiophene-chain lengths of three NDT-based polymers on the nanoscale morphologies and device performances of the active layers.

  3. Nanostructuring of Self-Assembled Porphyrin Networks at a Solid/Liquid Interface: Local Manipulation under Global Control

    Dr. Michiel J. J. Coenen, Dr. Tony Khoury, Prof. Maxwell J. Crossley, Dr. Bas L. M. Hendriksen, Dr. Johannes A. A. W. Elemans and Prof. Sylvia Speller

    Article first published online: 21 AUG 2014 | DOI: 10.1002/cphc.201402449

    Ground control to Major Tom: Global control over the self-assembly of tetraundecyl metal porphyrins into a monolayer at a solid/liquid interface is governed by the concentration and composition of the supernatant solution. Subsequent manipulation by nanoshaving with a scanning tunneling microscopy tip creates monolayer defects, which can mediate a decrease or increase in local surface density, or the insertion of a second species of the same shape.

  4. Dioxetane Scission Products Unchanged by Mechanical Force

    Jess M. Clough and Prof. Dr. Rint P. Sijbesma

    Article first published online: 21 AUG 2014 | DOI: 10.1002/cphc.201402365

    Illuminating mechanoluminescence: Dioxetane-based force-induced light emission from polymers is a powerful new way to characterize polymer behavior under stress. Here we reveal that the dioxetane is broken mechanically into products almost identical to those formed by heating at elevated temperatures (see figure). Excited- and ground-state degeneracy is thought to play a critical role in regulating the outcome of the mechanical scission process.

  5. Determination of Solubility Parameters of Ionic Liquids and Ionic Liquid/Solvent Mixtures from Intrinsic Viscosity

    Dr. Piyarat Weerachanchai, Yuewen Wong, Prof. Kok Hwa Lim, Prof. Timothy Thatt Yang Tan and Prof. Jong-Min Lee

    Article first published online: 21 AUG 2014 | DOI: 10.1002/cphc.201402345

    Viewing the Mix in 3D: The solvation power of ionic liquids and ionic liquid/solvent mixtures was studied by using an intrinsic viscosity method that allowed the determination of Hildebrand and Hansen solubility parameters, in particular, dispersion, polar and hydrogen-bonding solubility parameters. These partial solubility parameters can be visualized as coordinates in a 3D diagram, allowing illustration of the miscibility of different materials.
