  1. Synthesis, Properties, and Doping Behavior of Optically Active Polythiophenes Bearing a Bornyl Group

    Atsushi Matsumura, Kohsuke Kawabata and Hiromasa Goto

    Polythiophenes bearing a bornyl group as a side chain are synthesized. The polymers form chiral aggregations, despite steric hindrance of spherical side chains. Iodine doping generates charge carriers. The study of chiroptical properties and doping behavior indicates the generation of chiral charge carriers, referred to as “chiralions.”

  2. Condensed Mode Cooling for Ethylene Polymerization: Part II. The Effect of Different Condensable Comonomers and Hydrogen on Polymerization Rate

    Arash Alizadeh, Montree Namkajorn, Ekasith Somsook and Timothy F. L. McKenna

    Article first published online: 2 MAR 2015 | DOI: 10.1002/macp.201500023

    A systematic methodology is proposed for evaluation of the impact of the physical and chemical phenomena during gas phase ethylene copolymerization with comonomers. In addition, the effect of inert n-hexane on the rate of gas phase ethylene polymerization, both in the absence and presence of 1-hexene and hydrogen, is investigated, illustrating the counter-effects of the physical and chemical phenomena during this process.

    Front Cover: Bulk self-assembly of polystyrene-block-poly(N-isopropylacrylamide) (PS-b-PNIPAM) is shown to form microphase-separated films. After dispersing the films in ethanol, nanocylinders stabilized by polystyrene cores were obtained. These kinetically trapped nanocylinders exhibited thermo-/ultrasound-responsive shape transition properties. The transition process could be modulated by the balance between energy input and kinetic barrier. Further details can be found in the article by Y. Li, B. Peng,* and Y. Chen* on page 495.

    Back Cover: A one-handed helical supramolecular polymer membrane of 1,3,5-trisubstituted benzenes was successfully prepared via the quantitative photocyclic aromatization reaction of a cis-cisoidal poly(chiral substituted acetylene) membrane. The resulting one-handed supramolecular helicity of the resulting polymer membrane could be retained even after in situ removal of the chiral substituents in the membrane. Further details can be found in the article by L. Liu,* Q. Long, T. Aoki,* T. Namikoshi, Y. Abe, M. Miyata, M. Teraguchi, T. Kaneko, Y. Wang, and C. Zhang on page 530.
