      Cover: A stimulus-sensitive biohybrid material that discriminates between physiological and pathological urate concentrations is presented. As a urate sensor the Deinococcus radiodurans regulator protein HucR is used which crosslinks DNA and polyacrylamide to a hydrogel as a function of the urate concentration. Further details can be found in the article by C. Geraths, E. H. Christen, and W. Weber* on page 2103.

    1. Routes to Hydrogen Bonding Chain-End Functionalized Polymers (pages 2062–2091)

      Arthur Bertrand, Frédéric Lortie and Julien Bernard

      Article first published online: 7 NOV 2012 | DOI: 10.1002/marc.201200508

      This Review summarizes recent advances in the design of hydrogen bonding chain-end functionalized polymers through post-polymerization functionalization or introduction of binding motifs in the course of the polymerization.

    1. 3D Photofixation Lithography in Diels–Alder Networks (pages 2092–2096)

      Brian J. Adzima, Christopher J. Kloxin, Cole A. DeForest, Kristi S. Anseth and Christopher N. Bowman

      Article first published online: 18 OCT 2012 | DOI: 10.1002/marc.201200599

      Sedimentation of overhanging and unsupported structures is a problem in the fabrication of complex 3D structures using conventional stereolithographic techniques. The reversible nature of the Diels–Alder reaction allows this problem to be avoided by replacing the liquid resist with a solid resist formed from reversible crosslinks.

    2. Polymer Photovoltaic Cells Based on Polymethacrylate Bearing Semiconducting Side Chains (pages 2097–2102)

      Qian Liu, Ming Wang, Cuihong Li, Enquan Jin, Chun Du, Jianjun Zhou, Lin Li and Zhishan Bo

      Article first published online: 1 OCT 2012 | DOI: 10.1002/marc.201200414

      Thumbnail image of graphical abstract

      Polymethacrylate carrying lateral chromophores synthesized by free radical polymerization are used as donors for the fabrication of solar cells. As expected, polymer based solar cells with PC71BM as an acceptor demonstrate a PCE of 1.22%, which is two times higher than that of the corresponding small organic molecule-based solar cells.

    3. A Hydrogel Sensing Pathological Urate Concentrations (pages 2103–2108)

      Christian Geraths, Erik H. Christen and Wilfried Weber

      Article first published online: 19 OCT 2012 | DOI: 10.1002/marc.201200563

      Thumbnail image of graphical abstract

      A stimulus-responsive biohybrid material is described that rapidly dissolves at pathological concentrations of the gouty arthritis-causing metabolite urate. The gel consists of polyacrylamide and DNA that are crosslinked by the Deinococcus radiodurans-derived urate sensor HucR, which binds its specific target DNA motif at physiological urate concentrations and dissociates thereof at pathological concentrations.

    4. Synthesis of Novel Core Cross-Linked Star-Based Polyrotaxane End-Capped via “CuAAC” Click Chemistry (pages 2109–2114)

      Qiang Fu, Jing M. Ren, Shereen Tan, Jiangtao Xu and Greg G. Qiao

      Article first published online: 11 SEP 2012 | DOI: 10.1002/marc.201200489

      Thumbnail image of graphical abstract

      A novel cyclodextrin-based star polyrotaxane is prepared via the inclusion complexation of star polymer precursors with α-cyclodextrins, followed by an end-capping reaction via “click” chemistry with a modified chromophore. The resultant star polyrotaxane shows a unique core–shell structure by TEM micrograph as a result of considerable steric repulsion of the formed polyrotaxane arms.

    5. Palladium-Mediated Surface-Initiated Kumada Catalyst Polycondensation: A Facile Route Towards Oriented Conjugated Polymers (pages 2115–2120)

      N. Eric Huddleston, S. Kyle Sontag, Jenna A. Bilbrey, Gareth R. Sheppard and Jason Locklin

      Article first published online: 12 SEP 2012 | DOI: 10.1002/marc.201200472

      Thumbnail image of graphical abstract

      A palladium catalyst is used in the surface-initiated Kumada catalyst transfer polycondensation of poly(3-methylthiophene). Films up to 100 nm in thickness display backbone orientation perpendicular to the substrate. This catalyst system further advances the scope of conjugated polymer synthesis using KCTP.

    6. Facile Soap-Free Miniemulsion Polymerization of Methyl Methacrylate via Reverse Atom Transfer Radical Polymerization (pages 2121–2126)

      Gaohua Zhu, Lifen Zhang, Xiangqiang Pan, Wei Zhang, Zhenping Cheng and Xiulin Zhu

      Article first published online: 28 SEP 2012 | DOI: 10.1002/marc.201200492

      Thumbnail image of graphical abstract

      A facile soap-free miniemulsion polymerization of methyl methacrylate is successfully carried out via a reverse atom transfer radical polymerization (ATRP) technique, using a water-soluble potassium persulfate or V-50 both as the initiator and the stabilizer, and using an oil-soluble Cu(S2CN(C4H9)2)2 as the catalyst without adding any additional ligand. The results showed the “living”/controlled characteristics of ATRP and a good colloidal stability of the resultant latexes.

    7. Selenium/Tellurium-Containing Hyperbranched Polymers: Effect of Molecular Weight and Degree of Branching on Glutathione Peroxidase-Like Activity (pages 2127–2132)

      Joice Thomas, Zeyuan Dong, Wim Dehaen and Mario Smet

      Article first published online: 21 SEP 2012 | DOI: 10.1002/marc.201200519

      Thumbnail image of graphical abstract

      A series of novel hyperbranched polyselenides and polytellurides incorporating numerous catalytic groups in the macromolecule is successfully synthesized. The polymer catalyst with a higher molecular weight and degree of branching has higher GPx-like activity, indicating the importance of multiple catalytic sites at the branching units.

    8. Effect of Crystallization Kinetics on Microstructure and Charge Transport of Polythiophenes (pages 2133–2137)

      Kiarash Vakhshouri and Enrique D. Gomez

      Article first published online: 12 OCT 2012 | DOI: 10.1002/marc.201200531

      Thumbnail image of graphical abstract

      The crystallization kinetics can affect the microstructure and consequently charge transport of polythiophenes by changing the density of tie molecules. Rapid crystallization of P3HT and PBTTT results in higher density of tie molecules and higher charge carrier mobility. This suggests that controlling the crystallization kinetics might be an important factor for maximizing the charge mobility in semicrystalline polythiophene thin films.
