      Front Cover: Tough PS PC film could be obtained from direct UV irradiation due to photochemical crosslink of PS macromolecule chain. In addition, the irradiation also changes the wettability of the film from hydrophobicity to high hydrophilicity because of the formation of carboxyl groups upon PS latex surface. Further information can be found in the article by Y. Zhang, X. Hao, J. Zhou, Y. Zhang, J. Wang,* Y. Song,* and L. Jiang on page 2115.

      This review presents interfacial layers used in organic photovoltaic devices (OPVs) to improve their power conversion efficiency and long term stability. We summarize the recent progress obtained by including interlayers in OPVs, with regard to interfacial layers for efficient hole extraction or efficient electron extraction, as well as efficient hole or electron extraction via nano-patterned structures, in OPVs.

      Inspired by universal adhesive properties of mussel, we demonstrate a universal polymeric template for 1D assembly of various nanoparticles, including gold nanoparticles, iron oxide nanoparticles, and quantum dots. We also find that the length of the 1D assembly is tunable using hyaluronic acid-graft-catechol templates with various contour lengths.

    2. Tough and Hydrophilic Photonic Crystals Obtained from Direct UV Irradiation (pages 2115–2120)

      Yuqi Zhang, Xin Hao, Jinming Zhou, Youzhuan Zhang, Jingxia Wang, Yanlin Song and Lei Jiang

      Article first published online: 9 NOV 2010 | DOI: 10.1002/marc.201000495

      Thumbnail image of graphical abstract

      Tough PS PC film with high optical quality could be obtained from direct UV irradiation; the irradiation procedure also changes the wettability of the film from hydrophobicity to high hydrophilicity. The fabrication approach of these functional PCs will greatly extend the applications of PCs in special fields.

    3. Nanoparticle Vesicles Through Self Assembly of Cyclodextrin- and Adamantyl-Modified Silica (pages 2121–2126)

      Kathrin Isenbügel, Helmut Ritter, Robert Branscheid and Ute Kolb

      Article first published online: 29 NOV 2010 | DOI: 10.1002/marc.201000597

      Thumbnail image of graphical abstract

      The sum of the parts: the spontaneous formation of nanoparticle vesicles of cyclodextrin- and adamantyl-modified silica in water is presented. These structures exhibit interesting properties: e.g., exceptionally stable vesicles even after evaporation of the water and decomplexation with temperature or under influence of a competitive guest.

    4. Entanglement Transition in Hyperbranched Polyether-Polyols (pages 2127–2132)

      Christoph Tonhauser, Daniel Wilms, Yasmin Korth, Holger Frey and Christian Friedrich

      Article first published online: 19 OCT 2010 | DOI: 10.1002/marc.201000473

      Thumbnail image of graphical abstract

      The viscoelastic properties of hyperbranched polyglycerol have been investigated with respect to molecular weight. The scaling relation between zero shear viscosity and molecular weight presents an uncommon behavior, since starting with a critical value (equation image) entanglement dynamics can be observed due to “star-like” interactions at high molecular weights.

    5. Rapid Photocrosslinkable Thermoresponsive Injectable Polyphosphazene Hydrogels (pages 2133–2139)

      Thrimoorthy Potta, ChangJu Chun and Soo-Chang Song

      Article first published online: 19 OCT 2010 | DOI: 10.1002/marc.201000350

      Thumbnail image of graphical abstract

      The PBS solution of acrylated poly(organophosphazene) exhibited a solution state at room temperature, the solution was transformed into a transparent hydrogel (middle) at body temperature because of thermoresponsive physical crosslinking, and upon UV curing for 120s it resulted in a dually crosslinked hydrogel with an enhanced mechanical property (right). The hydrophobic interactions promoted the photocuring of the double bond of acrylate more than that of methacrylate.

    6. Anionic Synthesis and Rheological Characterization of Poly(p-methylstyrene) Model Comb Architectures with a Defined and Very Low Degree of Long Chain Branching (pages 2140–2145)

      Michael Kempf, Vitor C. Barroso and Manfred Wilhelm

      Article first published online: 19 OCT 2010 | DOI: 10.1002/marc.201000412

      Thumbnail image of graphical abstract

      The synthesis of well-defined model combs with a low degree of long chain branching using the grafting onto method, and their rheological behavior is described. The rheological measurements in oscillatory shear and extensional flow show pronounced differences between linear and branched topologies even for a low degree of branching.

    7. Microparticle-Supported Conjugated Polyelectrolyte Brushes Prepared by Surface-Initiated Kumada Catalyst Transfer Polycondensation for Sensor Applications (pages 2146–2150)

      Roman Tkachov, Volodymyr Senkovskyy, Ulrich Oertel, Alla Synytska, Marta Horecha and Anton Kiriy

      Article first published online: 21 OCT 2010 | DOI: 10.1002/marc.201000411

      Thumbnail image of graphical abstract

      A ‘grafting-fromapproach and polymer analogous transformations were applied for the preparation of polythiophene-based colloidal conjugated polyelectrolyte brushes. Optical properties of the resulting brushes were found to be highly sensitive to changes in surrounding chemical environment and thus they are promising materials for sensor applications.

    8. Fabrication of Microropes via Bi-electrospinning with a Rotating Needle Collector (pages 2151–2154)

      Guoqing Chang and Jianyi Shen

      Article first published online: 21 OCT 2010 | DOI: 10.1002/marc.201000463

      Thumbnail image of graphical abstract

      Double helical nanofilament microropes with diameters of less than 10µm and lengths up to 5cm are fabricated by a modified bi-electrospinning technique. The helicity of the microropes can be varied easily by adjusting the distance between two spinnerets. In principle, microropes consisting of three or more branches of different polymer bundles can be fabricated this way.

    9. Amphiphilic Block-Graft Copolymers with a Degradable Backbone and Polyethylene Glycol Pendant Chains Prepared via Ring-Opening Polymerization of a Macromonomer (pages 2155–2159)

      Xiaojin Zhang, Fujie Chen, Zhenlin Zhong and Renxi Zhuo

      Article first published online: 18 OCT 2010 | DOI: 10.1002/marc.201000392

      Thumbnail image of graphical abstract

      Amphiphilic block-graft copolymers with a hydrophobic degradable backbone and hydrophilic PEG pendant chains are synthesized via ring-opening polymerization of a macromonomer. The polymers have unimodal molecular weight distributions and moderate polydispersity indexes. The amphiphilic block-graft copolymers self-assemble in water forming stable micelle solutions with a narrow size distribution.

    10. Highly Selective Anionic Counterion-based Fluorescent Sensor for Hg2+ by Grafted Conjugated Polyelectrolytes (pages 2160–2165)

      Zhiyong Zhang, Quli Fan, Pengfei Sun, Lulin Liu, Xiaomei Lu, Bo Li, Yiwu Quan and Wei Huang

      Article first published online: 9 NOV 2010 | DOI: 10.1002/marc.201000419

      Thumbnail image of graphical abstract

      Grafted conjugated polyelectrolytes were synthesized for the first time and characterized. The polymers demonstrated properties of a convenient and efficient protocol for creating Hg2+ sensors. The unique character of the new material comes from an anionic counterion nature with no external cofactors, and imparts high selectivity and fast detection for mercury ion in a fluorescence probe. The concept may be potentially applied to create new sensors for monitoring other ions.

    11. Sharp Hydrophilicity Switching and Conformality on Nanostructured Surfaces Prepared via Initiated Chemical Vapor Deposition (iCVD) of a Novel Thermally Responsive Copolymer (pages 2166–2172)

      Mahriah E. Alf, Paul D. Godfrin, T. Alan Hatton and Karen K. Gleason

      Article first published online: 22 NOV 2010 | DOI: 10.1002/marc.201000452

      Thumbnail image of graphical abstract

      A thermally responsive polymer based onN-isopropylacrylamide (NIPAAm) with a sharp lower critical solution temperature (LCST) transition for facile, conformal, and substrate independent surface modification is presented. The novel polymer, p(NIPAAm-co-DEGDVE), synthesized via initiated chemical vapor deposition (iCVD), exhibits a relatively sharp LCST of ≈28.5±0.3 °C as determined via quartz crystal microbalance with dissipation monitoring (QCM-D).
