      Front Cover: The picture presents the energy-harvesting enzyme glucose oxidase (GOx) that is immobilized within the conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT). PEDOT is shown to be capable of transferring electrons directly from the FAD redox centre of GOx (shown as green). This discovery could result in development of new materials for biofuel cells. Further details can be found in the article by B. C. Thompson,* O. Winther-Jensen, J. Vongsvivut, B. Winther-Jensen, and D. R. MacFarlane on page 1293.

    1. Cell-mediated Delivery and Targeted Erosion of Vascular Endothelial Growth Factor-Crosslinked Hydrogels (pages 1231–1240)

      Sung Hye Kim and Kristi L. Kiick

      Version of Record online: 8 JUL 2010 | DOI: 10.1002/marc.201000130

      Thumbnail image of graphical abstract

      Cell receptor-responsive and targeted delivery of the vascular endothelial growth factor (VEGF) from noncovalently assembled, heparinized polymeric hydrogels is demonstrated. The hydrogel is formed via specific non-covalent interactions between 4-arm star poly(ethylene glycol)-heparin and dimeric VEGF. The VEGF is released selectively in the presence of the receptor VEGFR-2, and the hydrogel thus erodes. The released VEGF stimulates the phosphorylation of VEGFR-2, and exhibits mitogenic effects toward select cells.

    1. Polarizability of DNA Block Copolymer Nanoparticles Observed by Electrostatic Force Microscopy (pages 1242–1246)

      Mukhles Sowwan, Maryam Faroun, Elad Mentovich, Imad Ibrahim, Shayma Haboush, Fikri Emrah Alemdaroglu, Minseok Kwak, Shachar Richter and Andreas Herrmann

      Version of Record online: 2 JUL 2010 | DOI: 10.1002/marc.200900904

      Thumbnail image of graphical abstract

      Doping of DNA block copolymer micelles with ferrocene alters the electrical properties of the bioorganic nanoparticles. The incorporation of the payload changes their polarizability as revealed by electrostatic force microscopy measurements. This allows equipping of the self- assembled objects with an electrical tag for future sensing applications.

    1. A Novel Route for Fabricating Metal-Polymer Composite Nanoparticles with Phase-Separated Structures (pages 1267–1271)

      Hiroshi Yabu, Kazutaka Koike, Kiwamu Motoyoshi, Takeshi Higuchi and Masatsugu Shimomura

      Version of Record online: 27 APR 2010 | DOI: 10.1002/marc.201000007

      Thumbnail image of graphical abstract

      Au nanoparticles (NPs) and polymer composite particles with phase separation structures are prepared. Au NPs are successfully synthesized in amphiphilic block copolymer micelles, and then composite particles are formed by a simple solvent evaporation process from Au NPs and polymer solution. The phase separated structures (Janus and Core-shell) are controlled by changing the combination of polymers having differing hydrophobicity.

    2. Synthesis of Spherical Polyelectrolyte Brushes by Thermo-controlled Emulsion Polymerization (pages 1272–1275)

      Xiang Wang, Jun Xu, Li Li, Shuang Wu, Qingchuan Chen, Yan Lu, Matthias Ballauff and Xuhong Guo

      Version of Record online: 21 APR 2010 | DOI: 10.1002/marc.201000029

      Thumbnail image of graphical abstract

      A novel method called thermo-controlled emulsion polymerization is introduced to prepare spherical polyelectrolyte brushes with high grafting density of polyelectrolyte on the core surface, narrow particle size distribution and tunable brush thickness.

    3. Copper(0)-Mediated Living Radical Polymerization of Methyl Methacrylate in a Non-polar Solvent (pages 1276–1280)

      Ben D. Hornby, Andrew G. West, Jessica C. Tom, Carl Waterson, Simon Harrisson and Sébastien Perrier

      Version of Record online: 4 MAY 2010 | DOI: 10.1002/marc.201000031

      Thumbnail image of graphical abstract

      We report the controlled near-room temperature polymerization of MMA in a non-polar medium using copper(0) as the catalyst source. The effects of catalyst concentration and ligand concentrations have been studied, allowing for a 4-fold reduction in copper concentration versus conventional ATRP, while maintaining livingness and allowing the reaction to proceed effectively at room temperature. The use of a non-polar solvent expands the usefulness of copper(0)-mediated polymerization and allows for a greater variety of monomers to be accessed.

    4. Organoboron Polymers for Photovoltaic Bulk Heterojunctions (pages 1281–1286)

      Sebastiano Cataldo, Simone Fabiano, Francesco Ferrante, Francesco Previti, Salvatore Patanè and Bruno Pignataro

      Version of Record online: 17 MAY 2010 | DOI: 10.1002/marc.201000057

      Thumbnail image of graphical abstract

      Due to the boron vacant pz orbital and the extendedπ-conjugation, three-coordinate organoboron polymers behave as important electron acceptors. It shows remarkable photovoltaic effects when coupled with low band gap polythiophenes to form bulk heterojunctions. Open circuit voltages, short circuit currents and overall external quantum efficiencies obtained are among the highest reported for all-polymer PV cells.

    5. An Alternating Copolymer Derived from Indolo[3,2-b]carbazole and 4,7-Di(thieno[3,2-b]thien-2-yl)-2,1,3-benzothiadiazole for Photovoltaic Cells (pages 1287–1292)

      Version of Record online: 4 MAY 2010 | DOI: 10.1002/marc.201000062

      Thumbnail image of graphical abstract

      An alternating narrow bandgap conjugated copolymer (PICZ-DTBT, Eg = 1.83eV) derived from 5,11-di(9-heptadecanyl)indolo[3,2-b]carbazole and 4,7-di(thieno[3,2-b]thien-2-yl)-2,1,3-benzothiadiazole, is prepared by a palladium-catalyzed Suzuki coupling reaction. The copolymer absorbs light from 300–690 nm, exhibits two absorbance peaks at around 420 and 574 nm, and has good solution processability and thermal stability. Photovoltaic cells based on a PICZ-DTBT/PC71BM blend show power conversion efficiencies up to 2.4% under 80 mW · cm−2 illumination (AM 1.5) with a light response extending to 750 nm.

    6. Conducting Polymer Enzyme Alloys: Electromaterials Exhibiting Direct Electron Transfer (pages 1293–1297)

      Brianna C. Thompson, Orawan Winther-Jensen, Jitraporn Vongsvivut, Bjørn Winther-Jensen and Douglas R. MacFarlane

      Version of Record online: 9 JUN 2010 | DOI: 10.1002/marc.201000064

      Thumbnail image of graphical abstract

      The direct transfer of electrons from the enzyme glucose oxidase to the conducting polymer PEDOT is observed when the conducting polymer/enzyme material is synthesised using a vapour phase polymerisation “stuffing” process. The materials described could be used to produce electrodes for glucose biosensing or biofuel cells.

    7. Functionalization of Fullerenes with Cyclopentadienyl and Anthracenyl Capped Polymeric Building Blocks via Diels–Alder Chemistry (pages 1298–1305)

      Leena Nebhani and Christopher Barner-Kowollik

      Version of Record online: 20 MAY 2010 | DOI: 10.1002/marc.201000142

      Thumbnail image of graphical abstract

      Cyclopentadienyl (Cp) capped polymers [polyethylene glycols (PEGs)], react readily with fullerenes in a 1:1 molar ratio (relative to the amount of fullerenes and Cp-end groups) at ambient temperature within 5 min in the absence of any catalyst in a Diels–Alder (DA) reaction to provide fullerene-PEG hybrids. Similarly, anthracenyl capped PEGs react with fullerenes (in a 1:3 molar ratio) in DA reactions to yield the corresponding hybrids, albeit over a period of 1.5 h at 80 °C and a lesser conversion.
