      Front Cover: The picture presents a collage of an atomic force microscopy and a scanning electron microscopy image of a nanocomposite in which carbon nanotubes organise into honeycomb-like networks, templated by an ordered colloidal polymer matrix. The resulting nanocomposites can be strained by over 200% and still retain high conductivity when relaxed. Such carbon nanotube assemblies provide excellent control over the structure–property relationships for a range of potential applications. Further details can be found in the article by I. Jurewicz,* A. A. K. King, P. Worajittiphon, P. Asanithi, E. W. Brunner, R. P. Sear, T. J. C. Hosea, J. L. Keddie, A. B. Dalton*on page 609.

    1. Microphase Separation of Block Copolymer Thin Films (pages 591–608)

      Preparing long-range ordered arrays by block copolymer microphase separation is one of the most promising techniques for the fabrication of nanoscale arrays. We summarize the many techniques developed to induce ordering in the microphase separation of the block copolymer thin films. Evolution, order–order transitions and reversible switching microdomains are also considered, since they are very important in the ordered engineering of microphase separation of the block copolymer thin films. The outlook for this research area is discussed.

    1. Colloid-Assisted Self-Assembly of Robust, Three-Dimensional Networks of Carbon Nanotubes over Large Areas (pages 609–615)

      Izabela Jurewicz, Alice A. K. King, Patnarin Worajittiphon, Piyapong Asanithi, Eric W. Brunner, Richard P. Sear, Thomas J. C. Hosea, Joseph L. Keddie and Alan B. Dalton

      Version of Record online: 3 FEB 2010 | DOI: 10.1002/marc.200900799

      Thumbnail image of graphical abstract

      An approach to organize carbon nanotubes into highly ordered continuous three-dimensional networks using plasticized colloidal particles as a template is described. The resulting nanocomposites can be strained by over 200% and still retain high conductivity when relaxed. The methodology is inexpensive, upscalable, and could ultimately be generic for assembling a range of nanorods and nanowires.

    2. Supramolecular Nanocycles Comprising β-Cyclodextrin-click-Ferrocene Units: Rings of Rings of Rings (pages 616–618)

      Maricica Munteanu, Ute Kolb and Helmut Ritter

      Version of Record online: 3 FEB 2010 | DOI: 10.1002/marc.200900754

      Thumbnail image of graphical abstract

      A cyclodextrin derivative bearing ferrocene synthesized via click chemistry shows interesting self-assembly properties in aqueous solution, leading to supramolecular “ring like” structures. The hydrophobic ionic liquids open the rings by competitive displacement of ferrocene moieties from cyclodextrin cavity.

    3. Preparation of Clickable Poly(3-hydroxyalkanoate) (PHA): Application to Poly(ethylene glycol) (PEG) Graft Copolymers Synthesis (pages 619–624)

      Julien Babinot, Estelle Renard and Valérie Langlois

      Version of Record online: 3 FEB 2010 | DOI: 10.1002/marc.200900803

      Thumbnail image of graphical abstract

      A novel and convenient method to functionalize poly(3-hydroxyalkanoate)s (PHAs) has been developed. Grafting of poly(ethylene glycol) chains was successfully achieved using Cu-catalyzed azide-alkyne 1,3-dipolar cycloaddition. This approach represents a promising way to further extend PHA's chemical diversity.

    4. Use of a Profluorophore for Visualization of the Rupture of Capsules in Self-Healing Coatings (pages 625–628)

      Eric T. A. van den Dungen, Ben Loos and Bert Klumperman

      Version of Record online: 29 DEC 2009 | DOI: 10.1002/marc.200900728

      Thumbnail image of graphical abstract

      An important category of self-healing materials relies on the release of a healing agent from a capsule upon the occurrence of damage to the material. Visualization of the release of the healing agent is accomplished using a profluorophore. Release of the tetra-functional thiol healing agent converts the profluorophore into rhodamine, which results in strong fluorescence.

    5. Effects of Temperature and Solvent on the Energy Transfer and β-Phase Formation in the Iridium(III) Complex-Containing Polyfluorene in Solutions and as Suspended Nano-Particles (pages 629–633)

      Shu-Juan Liu, Wen-Juan Xu, Ting-Chun Ma, Qiang Zhao, Qu-Li Fan, Qi-Dan Ling and Wei Huang

      Version of Record online: 22 JAN 2010 | DOI: 10.1002/marc.200900739

      Thumbnail image of graphical abstract

      The formation of a second phase, β-phase, for the Ir(III) complex-containing polyfluorene was observed both in THF solution at low temperature and in the THF/H2O mixtures at room temperature. Phosphorescent polymer iamP2 nanoparticles were successfully prepared. Efficient energy transfer from polymer backbone host to iridium complex guest can be realized both in THF solution at low temperature and as suspended nanoparticles.

    6. Induction of Molecular Organization of Oligomers by Low-Energy Electrons (pages 634–639)

      Yiu-Ting Richard Lau, Lu-Tao Weng, Kai-Mo Ng, Manuel Kempf, Volker Altstädt, Jerold M. Schultz and Chi-Ming Chan

      Version of Record online: 22 JAN 2010 | DOI: 10.1002/marc.200900730

      Thumbnail image of graphical abstract

      An amorphous, semi-flexible oligomer is induced to order under low-energy electron irradiation. This novel method directly controls the ordering of an amorphous organic substrate at ambient temperature. Therefore, the fabrication of a millimeter-scaled ordered/disordered structural pattern of an organic thin film with a protective mask takes just a few minutes.

    7. Dual Responsive Block Copolymer Micelles Functionalized by NIPAM and Azobenzene (pages 640–644)

      Ze Feng, Li Lin, Zeng Yan and Yanlei Yu

      Version of Record online: 25 JAN 2010 | DOI: 10.1002/marc.200900777

      Thumbnail image of graphical abstract

      Obtained polymer micelles exhibited dual responsiveness and H-aggregation of the azobenzene moieties. Micellar size was temperature-dependent and encapsulated substance was released by varying temperature. Hydrophobicity of the micellar cores can be changed reversibly by light without disruption of the micelles or leaking of the encapsulated substance, which might be promising in catalyst and sensor technology.

    8. Highly Ordered Hexagonal Arrays of Hybridized Micelles from Bimodal Self-Assemblies of Diblock Copolymer Micelles (pages 645–650)

      Seong Il Yoo, Sang Hyun Yun, Hyeong Ki Kim and Byeong-Hyeok Sohn

      Version of Record online: 12 FEB 2010 | DOI: 10.1002/marc.200900790

      Thumbnail image of graphical abstract

      Hybridized micelles in a long-range hexagonal order were prepared by solvent-annealing on the bimodal self-assemblies of non-hybridizing micelles, the diameter and center-to-center distance of which were precisely adjusted by varying the mixing ratio of small to large micelles.

    9. Electronic Properties and Photovoltaic Performances of a Series of Oligothiophene Copolymers Incorporating Both Thieno[3,2-b]thiophene and 2,1,3-Benzothiadiazole Moieties (pages 651–656)

      Laure Biniek, Christos L. Chochos, Georges Hadziioannou, Nicolas Leclerc, Patrick Lévêque and Thomas Heiser

      Version of Record online: 12 FEB 2010 | DOI: 10.1002/marc.200900804

      A new series of low-bandgap copolymers has been synthesized by Stille cross-coupling. Materials have been characterized by UV-Visible absorption and cyclic voltammetry. A promising Voc (≈0.8 V) has been obtained in bulk heterojunction solar cells in combination with PCBM-C60. A maximum power conversion efficiency of 1.8% is achieved with a 1:4 donor polymer:PCBM-C70 weight ratio.

    10. A Rapid and Facile Synthesis of Nanofibrillar Polyaniline Using Microwave Radiation (pages 657–661)

      Marija R. Gizdavic-Nikolaidis, Dragomir R. Stanisavljev, Allan J. Easteal and Zoran D. Zujovic

      Version of Record online: 1 MAR 2010 | DOI: 10.1002/marc.200900800

      Thumbnail image of graphical abstract

      A novel method for fast and facile, room-temperature synthesis of polyaniline nanofibers is reported in this communication. Nanofibers of PANI are successfully obtained for the first time under microwave radiation in relatively high yield (76%) after only 5 min. This method provides a convenient and environmentally friendly way toward the large-scale design of high-quality advanced nanomaterials.

This novel finding offers a facile method to control molecular ordering and allows versatile patterning of ordered and disordered regions as imprinted by a mask.
