      Front Cover: A schematic representation of a Smectic A elastomer containing lithium ions is shown. Aromatic cores of the mesogen plus polymer backbone hinder lithium diffusion while ethylene oxide chains coordinate lithium ions and promote lithium diffusion within the lamellar layer. Further details can be found in the article by L. Ramón-Gimenez, R. Storz, J. Haberl, H. Finkelmann, and A. Hoffmann* on page 386.

    1. Synthesis of Hyperbranched Polyethylene Amphiphiles by Chain Walking Polymerization in Tandem with RAFT Polymerization and Supramolecular Self-Assembly Vesicles (pages 374–379)

      Xinbo Shi, Ye Zhao, Haiyang Gao, Ling Zhang, Fangming Zhu and Qing Wu

      Version of Record online: 24 JAN 2012 | DOI: 10.1002/marc.201100825

      A novel polymerization methodology, chain walking polymerization (CWP) followed by reversible addition fragmentation transfer (RAFT) polymerization, has been developed for efficient synthesis of hyperbranched polyethylene amphiphiles (HBPE-PDMAEMAs). The hyperbranched polyethylene amphiphiles can self-assemble into supramolecular polymer vesicles in aqueous solution. These hyperbranched polyolefin vesicles may be potentially useful in nanobiotechnology applications.

    2. The Naked-Eye Detection of NH3–HCl by Polyaniline-Infiltrated TiO2 Inverse Opal Photonic Crystals (pages 380–385)

      Cihui Liu, Guizhi Gao, Yuqi Zhang, Libin Wang, Jingxia Wang and Yanlin Song

      Version of Record online: 30 JAN 2012 | DOI: 10.1002/marc.201100575

      Thumbnail image of graphical abstract

      A reversible color change of a polyaniline-infiltrated TiO2 inverse opal photonic crystal (PC) film can be obtained when the PC is switched from an NH3 to HCl vapor environment. The naked-eye detection of NH3 and HCl vapors can be realized by a reversible color change of the PC film, which is very important for chemical and biological sensors.

    3. Anisotropic Ionic Mobility of Lithium Salts in Lamellar Liquid Crystalline Polymer Networks (pages 386–391)

      Laura Ramón-Gimenez, Rebekka Storz, Johannes Haberl, Heino Finkelmann and Anke Hoffmann

      Version of Record online: 8 FEB 2012 | DOI: 10.1002/marc.201100792

      Thumbnail image of graphical abstract

      New mesogenic monomers are designed to incorporate lithium salts into liquid crystalline polymer networks. The low molar mass host–guest systems exhibit layered structures and a high macroscopic anisotropy of ion mobility. In the first lithium-containing liquid crystalline polymer networks made from these monomers, this behavior is maintained and the macroscopic structure can be permanently fixed.

    4. Morphology Tailoring of Thin Film Block Copolymers on Patterned Substrates (pages 392–395)

      Xianggui Ye, Brian J. Edwards and Bamin Khomami

      Version of Record online: 30 JAN 2012 | DOI: 10.1002/marc.201100744

      Thumbnail image of graphical abstract

      By judiciously varying the mismatch between the spacing of the pattern and the bulk periodic spacing of the cylinder-forming block copolymer, the top surface affinity, and spot size, new morphologies can be achieved, such as honeycomb and ring structures, which do not appear in the bulk system.

    5. Water-Developable Poly(2-oxazoline)-Based Negative Photoresists (pages 396–400)

      Verena Schenk, Lisa Ellmaier, Elisabeth Rossegger, Matthias Edler, Thomas Griesser, Gerald Weidinger and Frank Wiesbrock

      Version of Record online: 19 JAN 2012 | DOI: 10.1002/marc.201100717

      Thumbnail image of graphical abstract

      Copoly(2-oxazoline)s bearing unsaturated side chains can be used for the formulation of negative photoresists, crosslinking of which is achieved by the functional principle of UV-induced thiol-ene reactions. These photoresists adhere to various substrates commonly used in printed circuit board industries. After illumination through a quartz mask and subsequent development in halogen-free solvents, these photoresists exhibit resolution in the 2 μm range.

    6. A Simple and Effective Approach to Vesicles and Large Compound Vesicles via Complexation of Amphiphilic Block Copolymer With Polyelectrolyte in Water (pages 401–406)

      Nisa V. Salim, Tracey L. Hanley, Lynne Waddington, Patrick G. Hartley and Qipeng Guo

      Version of Record online: 27 JAN 2012 | DOI: 10.1002/marc.201100839

      Thumbnail image of graphical abstract

      A simple, effective approach to trigger a spheres-to-vesicles morphological transition from amphiphilic block copolymer/polyelectrolyte complexes in aqueous solution is reported. Vesicles and large compound vesicles are prepared via complexation of polystyrene-block-poly(ethylene oxide) with poly(acrylic acid) in water and directly are visualized using cryo-TEM.

    7. Improving Hydrogen Adsorption Enthalpy Through Coordinatively Unsaturated Cobalt in Porous Polymers (pages 407–413)

      Shengwen Yuan, Desiree White, Alex Mason, Briana Reprogle, Magali S. Ferrandon, Luping Yu and Di-Jia Liu

      Version of Record online: 30 JAN 2012 | DOI: 10.1002/marc.201100797

      Thumbnail image of graphical abstract

      A porous organic polymer functionalized with bipyridine–cobalt complexes is prepared through copolymerization of a spirobifluorene and a bipyridine monomers using cobalt carbonyl as catalysts and coordination agent. Hydrogen adsorption enthalpy increases by over 30% upon removal of the carbonyl ligand and CO2 from the porous network by a simple thermal treatment

    8. Controlled Radical Polymerization Mediated by Amine–Bis(phenolate) Iron(III) Complexes (pages 414–418)

      Laura E. N. Allan, Jarret P. MacDonald, Amy M. Reckling, Christopher M. Kozak and Michael P. Shaver

      Version of Record online: 2 FEB 2012 | DOI: 10.1002/marc.201100872

      Thumbnail image of graphical abstract

      Facile recovery of white polymers is essential for the commercialization of controlled radical polymerization. A new family of highly active, benign iron catalysts, believed to operate through a unique dual-control mechanism, is reported. Despite the deep purple color of the complexes and polymerization media, simple precipitation yields pure white polymers with polydispersities as low as 1.1.

    9. Preparation of Responsive Micrometer-Sized Microgel Particles with a Highly Functionalized Shell (pages 419–425)

      Zifu Li, Man-Hin Kwok and To Ngai

      Version of Record online: 3 FEB 2012 | DOI: 10.1002/marc.201100747

      Thumbnail image of graphical abstract

      A facile method is reported for the preparation of uniform-sized multi-responsive microgel particles which have a highly functionalized shell and show the ability to load active ingredients as well as release them through pH changes or added calcium ions.

    10. Biological Glucose Metabolism Regulated Peptide Self-Assembly as a Simple Visual Biosensor for Glucose Detection (pages 426–431)

      Xiao-Ding Xu, Bing-Bing Lin, Jun Feng, Ya Wang, Si-Xue Cheng, Xian-Zheng Zhang and Ren-Xi Zhuo

      Version of Record online: 9 FEB 2012 | DOI: 10.1002/marc.201100689

      Thumbnail image of graphical abstract

      Peptide building blocks with self-assembly ability which could be regulated by a biological glucose metabolism were designed and synthesized. As the metabolic product, gluconic acid can trigger the protonation of peptide and induce phase transition. Because the glucose metabolism regulated self-assembly is based on the oxidation of glucose, it can be used as a visual biosensor for glucose detection.
