      Front Cover: Renewable castor-oil-based dendrimers are synthesized combining the efficient Passerini three component reaction with olefin cross-metathesis. After preparing the core molecule, iterative steps of the Pass erinireaction with 10-undecenal and 10-isocyanodec-1-ene for branching, and olefin cross-metathesis with tert-butyl acrylate, followed by hydrogenation and hydrolysis allow the synthesis of a third-generation dendrimer. Further details can be found in the article by O. Kreye, D. Kugele, L. Faust, and M. A. R. Meier* on page 317.

      Due to the cooperative nature of liquid crystalline materials, highly efficient photoalignment and phototriggered migrating motions are realized. This review article focuses on the studies on photoinduced and photo-triggered motions in azobenzene liquid crystalline polymer films at mesoscopic and microscopic levels. Such newly emerged photoresponsive systems are expected to provide new possibilities and applications in polymer thin film technologies.

      The self-polymerization of dopamine is extended to incorporate 5-hydroxyindazole into the polymerization system. The structurally similar indazole can oxidatively couple in the same fashion as dopamine, proof that the polymerization reaction is expandable to other materials for new green chemistry reactions.

    2. Bioreducible Nanocapsules Prepared from the Self-assembly of Branched Polymer in Nanodroplet (pages 298–302)

      Long-Hai Wang, Sheng-Gang Ding, Jun-Jie Yan and Ye-Zi You

      Version of Record online: 12 DEC 2013 | DOI: 10.1002/marc.201300749

      Thumbnail image of graphical abstract

      A temperature-responsive PEG-based branched polymer with disulfide bonds in its backbone is prepared via RAFT polymerization. This PEG-based branched polymer is not amphiphlic polymer, but it can self-assemble into bioreducible nanocapsules in aqueous nanodroplets. The size of formed bioreducible nanocapsules can be easily controlled.

    3. A Reversible Multi-Stimuli-Responsive Fluorescence Probe and the Design for Combinational Logic Gate Operations (pages 303–308)

      Hongyan Xia, Yangyang Xu, Guang Yang, Hao Jiang, Gang Zou and Qijin Zhang

      Version of Record online: 12 DEC 2013 | DOI: 10.1002/marc.201300829

      The interconversion between the colored and colorless form of spiropyran (close-to-opened isomerization of spiropyran when exposure to UV irradiation or upon pH stimuli) can act as the driving force to modulate the fluorescence of the red-phase PDA owing to the fluorescene resonance energy transfer (FRET) between the red-phase PDA and the open merocyanine (MC) form of spiropyran. Because of the reversible chemical nature of the spiropyran group and the reversible thermochromatic transition of the hybrid PDA vesicles, the fluorescence could be reversibly switched on and off.

    4. Gradient Structure-Induced Temperature Responsiveness in Styrene/Methyl Methacrylate Gradient Copolymers Micelles (pages 309–316)

      Chao Zheng, Haiying Huang and Tianbai He

      Version of Record online: 18 DEC 2013 | DOI: 10.1002/marc.201300769

      Thumbnail image of graphical abstract

      Temperature responsiveness in gradient copolymer micelles is investigated. Three different structural transitions could be induced by temperature at different solvent compositions. Combining the model analysis, temperature responsiveness is ascribed to the gradient structure along the chain, which is believed to be an intrinsic property in gradient copolymer micelles.

    5. Divergent Dendrimer Synthesis via the Passerini Three-Component Reaction and Olefin Cross-Metathesis (pages 317–322)

      Oliver Kreye, Dennis Kugele, Lorenz Faust and Michael A. R. Meier

      Version of Record online: 6 DEC 2013 | DOI: 10.1002/marc.201300779

      Thumbnail image of graphical abstract

      Divergent dendrimers of third generation, containing ester and amide functionalities, are synthesized using iterative steps of the Passerini three-component reaction with castor oil-derived platform chemicals, followed by olefin cross-metathesis with tert-butyl acrylate, hydrogenation, and hydrolysis.

    6. A Stimuli-Responsive Nanogel-Based Sensitive and Selective Fluorescent Sensor for Cr3+ with Thermo-Induced Tunable Detection Sensitivity (pages 323–329)

      Xuejuan Wan, Haiyang Liu, Shen Yao, Tianqi Liu and Youwei Yao

      Version of Record online: 9 DEC 2013 | DOI: 10.1002/marc.201300810

      Fluorescent thermo-responsive nanogel-based Cr3+ sensor with tunable detection sensitivity is fabricated via free radical emulsion copolymerization. The obtained nanogel exhibits prominent fluorescence OFF–ON switching after the recognition of Cr3+ in water. Ascribing to the phase transition behavior of responsive polymer matrix, detection performance of the nanogel can be further optimized at elevated temperature with a detection limit of 9.1 × 10−8m.

    7. Quadrangular Prism: A Unique Self-Assembly from Amphiphilic Hyperbranched PMA-b-PAA (pages 330–336)

      Xiaoqiang Xue, Fang Li, Wenyan Huang, Hongjun Yang, Bibiao Jiang, Yiliang Zheng, Dongliang Zhang, Jianbo Fang, Lizhi Kong, Guangqun Zhai and Jianhai Chen

      Version of Record online: 6 DEC 2013 | DOI: 10.1002/marc.201300743

      Thumbnail image of graphical abstract

      The unique regular quadrangular prisms with the large microstructure are assembled on amorphous hyperbranched poly(methyl acrylate)-block-poly(acrylic acid) (HBPMA-b-PAA), which is mainly driven by a balance of contributions to the hydrogen bond interactions, the interfacial energy, and the repulsive interactions among unimolecular micelles. The formation of aggregates mainly depends on external pH-stimuli and the polymer concentration.

    8. Main-Chain Supramolecular Polymers Based on Orthogonal Benzo-21-Crown-7/Secondary Ammonium Salt and Terpyridine/Metal Ion Recognition Motifs (pages 337–343)

      Yu-Kui Tian and Feng Wang

      Version of Record online: 9 DEC 2013 | DOI: 10.1002/marc.201300742

      The multiple hydrogen bonding-strengthened hydrogels are synthesized and this bilayer hydrogel with different cross-linking density can curl up automatically into a 3D tube. At an intracellular level of GSH, cells-seeded bilayer gel sheet self-folds into a 3D tubular scaffold meanwhile maintaining better viability. This self-shaping 3D hydrogel tube holds great potential as a programmable tissue engineering scaffold.

    10. Bio-Inspired Dopamine Functionalization of Polypyrrole for Improved Adhesion and Conductivity (pages 350–354)

      Version of Record online: 13 DEC 2013 | DOI: 10.1002/marc.201300761

      Thumbnail image of graphical abstract

      Electrically conductive polypyrrole (PPy) is functionalized by a mussel-inspired “sticky” biomolecule dopamine (DA). After modification, the PPy morphology changes from being globular to fibrous. The PPy functionalized with a small amount of DA exhibits an excellent adhesion property and improved electrical conductivity without sacrificing biocompatibility. These new features broaden the potential applications of PPy.

      A new approach is reported for the preparation of a graphene–epoxy flexible transparent capacitor obtained by graphene–polymer transfer and UV-induced bonding. SU8 resin is employed as a supporting layer after spinning and UV curing. Two G/SU8 membranes are bonded together by using an epoxy photocurable formulation based on a cycloaliphatic epoxy resin. The obtained material shows a stable and clear capacitive behavior.

    12. Effect of Thermal Annealing on the Surface Properties of Electrospun Polymer Fibers (pages 360–366)

      The effect of thermal annealing on the properties of electrospun polymer fibers is investigated. Poly(methyl methacrylate) and polystyrene fibers are fist prepared by electrospinning, followed by thermal annealing processes. After the electrospun fibers are thermally annealed, the roughness of the surfaces of the fibers decreases. The water contact angles of the annealed polymer fibers also decrease with the annealing time.
