  1. A Generalized Packing Model for Bulk Crystalline Regioregular Poly(3-alkylthiophenes) with Extended Side Chains

    Anne Bohle, Dmytro Dudenko, Nils Koenen, Daniel Sebastiani, Sybille Allard, Ullrich Scherf, Hans Wolfgang Spiess and Michael Ryan Hansen

    The crystalline form I of regioregular poly(3-alkylthiophenes) with extended side chains is shown to crystallize in the space group P21/c from a combination of solid-state NMR experiments and condensed-phase nucleus-independent chemical shift calculations.

  2. Condensed Mode Cooling for Ethylene Polymerization: Part IV. The Effect of Temperature in the Presence of Induced Condensing Agents

    Fabiana N. Andrade and Timothy F. L. McKenna

    The effect of adding chemically inert alkanes to the reactor during gas phase polymerization of ethylene has a number of complex, often contradictory effects. One of these is that, at constant pressure of ethylene, increasing the reactor temperature in the presence of an induced condensing agent leads to a lower observable reaction rate.

  3. One-Step Spontaneous Formation of Dual Wrinkling on Uniform-Sized Microparticles Induced by Surface

    Jinsol Im, Dongik Yoo, Jihoon Kim, Sukeun Yoon and Kuk Young Cho

    Dual wrinkling structure on the surface of uniform-sized biodegradable microparticles is prepared by using blends of hydrophobic polymer and amphiphilic block copolymer and by introducing dimple-forming organic phase change materials. Both labyrinthine and hexagonal dimple structures are spontaneously formed from the conventional microparticle fabrication procedure of the solvent-emulsion evaporation method.

  4. Conjugated Side Chain Tuning Effect of Indacenodithieno[3,2-b]thiophene and Fluoro-Benzothiadiazole-Based Regioregular Copolymers for High-Performance Organic Field-Effect Transistors

    Henry Opoku, Ji Young Lee, Keun Cho, Benjamin Nketia-Yawson, Bogyu Lim and Yong-Young Noh

    Version of Record online: 19 JUL 2017 | DOI: 10.1002/macp.201700225

    Two regioregular indacenodithieno[3,2-b]thiophene and fluoro-benzothiadiazole-based donor–acceptor type copolymers with different conjugated side chains of hexyl-phenyl or hexyl-thienyl are synthesized to study the effects of the side chain on performance of organic field-effect transistors (OFETs). Top-gate/bottom-contact OFETs with a hexyl-thienyl substituted polymer show higher hole mobility up to 0.211 than 0.086 cm2 V−1 s−1 for the polymer with hexyl-phenyl side chains.

  5. Combining Staudinger Reductive Amination and Amidification for the Control of Surface Hydrophobicity and Water Adhesion by Introducing Heterobifunctional Groups: Post- and Ante-Approach

    Emna El Kout, Rawia Ben Trad, Mejda El Kateb, Mohammed Beji, Jean-Pierre Laugier, Guilhem Godeau, Frédéric Guittard and Thierry Darmanin

    Version of Record online: 19 JUL 2017 | DOI: 10.1002/macp.201700250

    Here, using a Staudinger reductive amination and amidification, it is shown how bifunctional monomers can be prepared easily and can be used to control the surface morphology and hydrophobicity.
