      Front Cover: The image presents a superhydrophobic surface, fabricated using a modified electrostatic process. The electrosprayed surface consists of micrometer-sized polycaprolactone droplets and interconnecting nanofibres. Such surfaces are superhydrophobic – they exhibit a water contact angle greater than 172° and a sliding angle of 14° – without any chemical modification or post-process treatment. Further information can be found in the article by H. Yoon, J. H. Park, and G. H. Kim*on page 1435.

    1. Water-Soluble Conjugated Polymers for Fluorescent-Enzyme Assays (pages 1405–1421)

      Fude Feng, Libing Liu, Qiong Yang and Shu Wang

      Version of Record online: 20 MAY 2010 | DOI: 10.1002/marc.201000020

      This Feature Article highlights recent developments of water-soluble conjugated polymers (CPs) for fluorescent enzyme assays. Proteases, kinases, oxidases, esterases, transferases, and nucleases are described as detection targets. Three signal transduction mechanisms, electron transfer, fluorescence resonance energy transfer, and aggregation/conformation change of CPs, are discussed. Potential challenges and future directions in this field are also presented.

    1. Synthesis of Amphiphilic Mushroom Cap-shaped Colloidal Particles towards Fabrication of Anisotropic Colloidal Crystals (pages 1422–1426)

      Liang Xu, Heng Li, Xi Jiang, Jingxia Wang, Lin Li, Yanlin Song and Lei Jiang

      Version of Record online: 22 JUN 2010 | DOI: 10.1002/marc.201000156

      Thumbnail image of graphical abstract

      An anisotropic colloidal crystal was obtained by using amphiphilic mushroom cap-shaped colloidal particles as building blocks. This simple fabrication approach, based on the wettability difference of the opposite side of the latex particle, offers a new way for self-assembly of anisotropic colloidal crystal by amphiphilic design of particle.

    2. Synthesis and Characterization of Nanocomposites Based on Functional Regioregular Poly(3-hexylthiophene) and Multiwall Carbon Nanotubes (pages 1427–1434)

      Florian Boon, Simon Desbief, Lorenzo Cutaia, Olivier Douhéret, Andrea Minoia, Benoît Ruelle, Sébastien Clément, Olivier Coulembier, Jérôme Cornil, Philippe Dubois and Roberto Lazzaroni

      Version of Record online: 30 JUN 2010 | DOI: 10.1002/marc.201000183

      Thumbnail image of graphical abstract

      This paper reports on the dispersion of MWCNTs in poly(3-hexylthiophene) matrices with the assistance of covalent or non-covalent functionalization. Functional P3HTs are prepared with tunable end-groups designed to interact with the CNT surface and therefore increase their affinity for the polymer matrix. Morphological studies show a specific organization of P3HT nanostructures around the CNTs, which is rationalized with molecular modeling simulations.

    3. A Superhydrophobic Surface Fabricated by an Electrostatic Process (pages 1435–1439)

      Hyeon Yoon, Jong Ha Park and Geun Hyung Kim

      Version of Record online: 31 MAY 2010 | DOI: 10.1002/marc.201000131

      Thumbnail image of graphical abstract

      A newly fabricated superhydrophobic surface using a simple electrostatic process (electrospraying poly(ε-caprolactone) particles on the surface of water target). The surface was prepared from accumulated micro-sized droplets and nanofibres. Through this process, we obtained a superhydrophobic surface with a water contact angle greater than 172° and a sliding angle of 14° without any chemical modification and post-process treatment.

    4. Recyclable Spherical Polyelectrolyte Brushes Containing Magnetic Nanoparticles in Core (pages 1440–1443)

      Kaimin Chen, Yan Zhu, Li Li, Yan Lu and Xuhong Guo

      Version of Record online: 22 JUN 2010 | DOI: 10.1002/marc.201000195

      Thumbnail image of graphical abstract

      Recyclability of spherical polyelectrolyte brushes is obtained by introducing nanosized magnetite particles into the polystyrene core before photoemulsion polymerization. Their stability can be controlled by adjusting the magnetite content, acrylic acid (AA) content and pH of the emulsion.

    5. Hydrazine as a Nucleophile and Antioxidant for Fast Aminolysis of RAFT Polymers in Air (pages 1444–1448)

      Wenqing Shen, Qian Qiu, Yang Wang, Miao Miao, Bingshu Li, Tianshu Zhang, Aoneng Cao and Zesheng An

      Version of Record online: 22 JUN 2010 | DOI: 10.1002/marc.201000154

      Thumbnail image of graphical abstract

      The bifunctional role of hydrazine as a potent nucleophile and antioxidant is investigated for the rapid aminolysis of RAFT polymers within minutes in air with effective suppression of the formation of disulfides. This simple protocol using a single reagent for the efficient preparation of polymer thiols from RAFT polymers in air will promote their use in a number of technologies such as polymer-bioconjugate and thiol-ene click chemistry.

    6. Patterning of Tailored Polycarbonate Based Non-Chemically Amplified Resists Using Extreme Ultraviolet Lithography (pages 1449–1455)

      Anguang Yu, Heping Liu, James P. Blinco, Kevin S. Jack, Michael Leeson, Todd R. Younkin, Andrew K. Whittaker and Idriss Blakey

      Version of Record online: 30 JUN 2010 | DOI: 10.1002/marc.201000117

      Thumbnail image of graphical abstract

      A series of high-performance polycarbonates has been prepared with glass-transition temperatures and decomposition temperatures that are tunable by varying-repeat-unit chemical structure. Patterning by taking advantage of a molecular-weight solubility switch has been achieved with extreme ultraviolet lithography and the importance of resist-developer interactions has been demonstrated.

    7. PNIPAM Copolymers Containing Light-Responsive Chromophores: A Method Toward Molecular Logic Gates (pages 1456–1461)

      Florian D. Jochum, F. Romina Forst and Patrick Theato

      Version of Record online: 22 JUN 2010 | DOI: 10.1002/marc.201000146

      Thumbnail image of graphical abstract

      The synthesis of thermo-responsive PNIPAM copolymers containing fulgimide chromophores is described, yielding copolymer series exhibiting a LCST in water that is hardly influenced by the amount of incorporated dye. Furthermore, the photocyclization of the fulgimide, which is induced by UV irradiation, does not effect a LCST change. This leads to the realization of a logic “NOT A”, while the corresponding azobenzene containing PNIPAM results in a logic “A implies B”.

    8. Direct Synthesis of Poly(potassium 3-sulfopropyl methacrylate) Cylindrical Polymer Brushes via ATRP Using a Supramolecular Complex With Crown Ether (pages 1462–1466)

      Youyong Xu, Andreas Walther and Axel H. E. Müller

      Version of Record online: 12 JUL 2010 | DOI: 10.1002/marc.201000157

      Thumbnail image of graphical abstract

      We have employed a supramolecular complex between ionic monomer potassium 3-sulfopropyl methacrylate and crown ether 18-crown-6 to directly grow a strong anionic cylindrical polymer brush from a hydrophobic poly-initiator without monomer protection via atom transfer radical polymerization in polar solvent dimethyl sulfoxide. The wormlike conformation of the brush is confirmed by various characterization techniques. The highly water-soluble anionic brush can be potentially applied as a template for one-dimensional inorganic/organic hybrid nanomaterials.

    9. Synthesis and Chain-Length Dependence of the Electronic Properties of π-Conjugated Dithieno[3,2-b:2′,3′-d]pyrrole (DTP) Oligomers (pages 1467–1472)

      Ali Yassin, Philippe Leriche and Jean Roncali

      Version of Record online: 22 JUN 2010 | DOI: 10.1002/marc.201000174

      Thumbnail image of graphical abstract

      The analysis of the chain-length dependence of the electronic properties of the strongly luminescent dithienopyrrole oligomers shows that the predicted bandgap of an ideal polymer chain should be considerably smaller than known experimental results. This discrepancy is discussed in terms of reactivity of the DTP unit.

    10. Assembly of Anionic Conjugated Polymer with 6-O-Modified PNP-β-Galactoside for Fluorescence Logic-signal-based Multiplex Detections of Enzymes (pages 1473–1478)

      Ya-juan Wang, Bao-juan Xin, Xin-rui Duan, Guo-wen Xing and Shu Wang

      Version of Record online: 22 JUN 2010 | DOI: 10.1002/marc.201000165

      Thumbnail image of graphical abstract

      Anionic conjugated polymer (PFP-SOmath image) is assembled with a novel enzymatic substrate 6-O-modified PNP-β-galactoside (1) for sensitive multiplex enzyme detections. Four types of logic gates including YES, INH, NAND and AND are successfully constructed and utilized for multiplex detections of lipase and β-galactosidase in one tube.
