      Front Cover: The image shows block copolymer micelles with near-infrared (NIR) dye. Photon-to-heat conversion of the dye by directional scanning of a laser results in locally generated heat on a NIR-dye-containing block copolymer micelle film. This allows for controlling the self-assembled structure, in which the molten and deformed spherical micelles are fused along the scanning direction, leading to cylinder-like micelles. Further details can be found in the article by H. Acharya, B. Yoon, Y. J. Park, I. Bae, and C. Park*on page 1071.

    1. Combining Living Anionic Polymerization with Branching Reactions in an Iterative Fashion to Design Branched Polymers (pages 1031–1059)

      Tomoya Higashihara, Kenji Sugiyama, Hee-Soo Yoo, Mayumi Hayashi and Akira Hirao

      Version of Record online: 9 MAR 2010 | DOI: 10.1002/marc.200900773

      This paper reviews the successive synthesis of star-branched polymers, graft (co)polymers, and dendrimer-like star-branched polymers by a common featured iterative methodology with its stepwise assembly of repeating units. The methodology involves two steps; (a) a preparation of a repeating unit and (b) a connection of the resulting repeating unit to other same unit, followed by the repetition of the two steps to successively synthesize a series of well-defined branched polymers.

    1. Homogeneous Detection of Trypsin in Protein Mixtures Based on Fluorescence Resonance Energy Transfer between Anionic Conjugated Polymer and Fluorescent Probe (pages 1060–1064)

      Qing Zhu, Ruoyu Zhan and Bin Liu

      Version of Record online: 29 MAR 2010 | DOI: 10.1002/marc.200900909

      Thumbnail image of graphical abstract

      A novel and simple method is developed for trypsin detection in homogeneous solution. Trypsin is in situ selectively labeled by F-BSF, and the labeled trypsin then serves as the bridge to bring a negatively charged CP and F-BSF into close proximity for energy transfer. This strategy is not limited to trypsin or positively charged proteins, but could also be generally applicable to negatively charged proteins when suitable polymers and specific fluorescent probes are chosen. In addition, this method does not require any separation steps, which should facilitate high-throughput protease screening and drug discovery.

    2. Fabrication of Diverse Microcapsule Arrays of High Density and Good Stability (pages 1065–1070)

      Jie Yang and Changyou Gao

      Version of Record online: 21 APR 2010 | DOI: 10.1002/marc.200900901

      Thumbnail image of graphical abstract

      Microcapsule arrays were fabricated through covalent binding between glutaraldehyde modified microcapsules and PAH patterns created by microcontact printing. They showed a high density and good stability, which could survive through successive incubation in solutions of high ionic strength and extreme pHs.

    3. Block Copolymer Micelles with Near Infrared Metal Phthalocyanine Dyes for Laser Induced Writing (pages 1071–1077)

      Himadri Acharya, Bokyung Yoon, Youn Jung Park, Insung Bae and Cheolmin Park

      Version of Record online: 17 MAY 2010 | DOI: 10.1002/marc.201000032

      Thumbnail image of graphical abstract

      Metal-containing (CoII, MnII, and NiII) phthalocyanine (Pc) dyes dispersed in a non-polar medium based on amphiphilic block copolymer micelles of poly[styrene-block-(4-vinylpyridine)] (PS-b-P4VP) and poly[styrene-block-(acrylic acid)] (PS-b-PAA) copolymers are investigated. Linear enhancement of Q-bands in the UV–vis absorption spectra with dye concentration confirms the good dispersion. Laser absorption by a thin monolayered PS-b-P4VP micelle film with Ni-Pc allowed the writing of line patterns.

    4. High-Density Glycosylation of Polymer Membrane Surfaces by Click Chemistry for Carbohydrate–Protein Recognition (pages 1078–1082)

      Cang Wang, Jian Wu and Zhi-Kang Xu

      Version of Record online: 24 MAR 2010 | DOI: 10.1002/marc.200900866

      Thumbnail image of graphical abstract

      Towards mimicking carbohydrate–protein interactions, construction of high-density glycosylated membrane surface is a prerequisite to overcome the limitation of weak affinity. Click chemistry with its high yield is proved to be one of the most reliable glycosylation methods for fabricating desirable glycosyl density. The high-density glucosylated membrane shows excellent carbohydrate–protein recognition capability with Con A by glycoside cluster effect.

    5. Copolymerization of Ethylene with Sterically Hindered 3,3-Dimethyl-1-Butene Using a Chain-Walking Pd-Diimine Catalyst (pages 1083–1089)

      Peng Xiang and Zhibin Ye

      Version of Record online: 13 APR 2010 | DOI: 10.1002/marc.201000014

      Thumbnail image of graphical abstract

      Successful copolymerization of ethylene with sterically hindered γ-trisubstituted 3,3-dimethyl-1-butene is demonstrated with the use of a chain-walking Pd-diimine catalyst. Appreciable comonomer incorporation with contents up to 3 mol-% was achieved in the copolymers despite its steric bulkiness.

    6. Synthesis of New Pyridazine-Based Monomers and Related Polymers for Photovoltaic Applications (pages 1090–1094)

      David Gendron, Pierre-Olivier Morin, Ahmed Najari and Mario Leclerc

      Version of Record online: 4 MAY 2010 | DOI: 10.1002/marc.201000038

      Thumbnail image of graphical abstract

      Aromatic compounds incorporating a pyridazine core are synthesized. The synthesis involves a simple condensation reaction and ring closure procedure to afford four new derivatives. The monomers are then polymerized with a 2,7-carbazole unit to furnish three polymers. The resulting conjugated polymers show a great potential in organic solar cells due to their optimized HOMO, LUMO, and bandgap energy levels.

    7. Ultrafast Responsive Poly- (N-isopropylacrylamide) Gel Produced by Cryostructuring of Self-crosslinkable Polymer Microgels (pages 1095–1100)

      Harald Kirsebom, Bo Mattiasson and Igor Yu. Galaev

      Version of Record online: 17 MAY 2010 | DOI: 10.1002/marc.201000015

      Thumbnail image of graphical abstract

      Macroporous thermoresponsive gels were prepared by structuring and crosslinking particles in a semi frozen state. This process yields in a simple one-step procedure a thermoresponsive gel composed of densely packed particles. Due to the fast individual response of the particle the structured gel also exhibit a rapid response to temperature changes.

    8. Orientation and Dynamics of ZnO Nanorod Liquid Crystals in Electric Fields (pages 1101–1107)

      Matthias Zorn, Muhammad Nawaz Tahir, Björn Bergmann, Wolfgang Tremel, Chris Grigoriadis, George Floudas and Rudolf Zentel

      Version of Record online: 18 MAY 2010 | DOI: 10.1002/marc.201000049

      Thumbnail image of graphical abstract

      ZnO nanorod polymer hybrids can be dispersed in a PS oligomer matrix to form LC phases. Application of electric field changes the orientation of the liquid crystal from planar (parallel to the substrate) to homeotropic (perpendicular) in full analogy to the switching of low molecular liquid crystals.

      Back Cover: The image presents a novel and simple conjugated polymer–fluorescent probe based platform for trypsin detection from protein mixtures in homogeneous solution. This platform takes advantage of specific interaction between the probe and the active site of trypsin and the electrostatic interaction between the polymer and the protein to mediate energy transfer between the polymer and the probe. This method does not require any separation steps, which should facilitate high-throughput protease screening and drug discovery. Further details can be found in the article by Q. Zhu, R. Zhan, and B. Liu*on page 1060.
