    Ionic liquid-functionalized MWCNTs consisting of vinyl immidazolium cations and lipophilic tetrafluoroborate counteranions were synthesized and used as a novel crosslinking agent for the preparation of a new absorbent gel. The prepared MWCNT-based polymeric gel (ILMPG) exhibits high organic solvent absorbency, fast organic solvent absorption rate, and good reusability. ILMPG does not swell in water and can potentially be used for cleaning oil and organic solvent spills on water.

  2. One-Pot synthesis of functional poly(methacrylate) by ATRP and 1,8-Diazacyclo-[5,4,0]undec-7-ene catalyzed transesterification

    A facile one-pot process has been developed for the synthesis of functional poly(methacrylate)s by the organic 1,8-diazacyclo-[5,4,0]undec-7-ene (DBU) catalyzed trans-esterification and ATRP. The two reactions are carried out without interference and the obtained polymers have controllable molecular weights with narrow dispersity.

    Solubility switching of fluorescent polymer films via lewis acid–base vapor treatments

    Shotaro Hayashi and Toshio Koizumi

    Article first published online: 25 AUG 2014 | DOI: 10.1002/pola.27366

    Fluorescence and solubility switching of a pyridine-fluorene alternating copolymer film via Lewis acid (BF3-OEt2)-base (Et3N) vapor treatments is reported. The solubility switching of the polymer film via the Lewis acid-base vapor treatment method could be applied to a pattern development.

  4. Rapid metal-free macromolecular coupling via In Situ nitrile oxide-activated alkene cycloaddition

    Michael J. Isaacman, Weibin Cui and Luke S. Theogarajan

    Article first published online: 25 AUG 2014 | DOI: 10.1002/pola.27371

    Metal-free polymer-polymer conjugation is crucial to the development of smart materials, especially for drug delivery and biosensing. A scalable, versatile and modular procedure is presented for the synthesis of ABA triblock copolymers based on 1,3 dipolar cycloaddition. The versatility of the approach is demonstrated by coupling both hydrophilic and hydrophobic A blocks with a polysiloxane B block. Hydrophilic A blocks imparting stealth, thermoresponsive, and self-assembled nanopatterning behavior were successfully coupled, thus illustrating the modularity of the approach.

  5. Tuning the energy gap of conjugated polymer zwitterions for efficient interlayers and solar cells

    Article first published online: 25 AUG 2014 | DOI: 10.1002/pola.27349

    Thumbnail image of graphical abstract

    Six narrow energy gap conjugated polymer zwitterions (CPZs) comprised of diketopyrrolopyrrole (DPP) and iso-indigo (iIn) backbones with pendant sulfobetaine (SB) solubilizing chains were synthesized. Probing the electronic properties and surface-metal interactions of the CPZs revealed energy gaps from 1.7 to 1.2 eV, and a 0.9 eV reduction in the work function of Ag. As buffer layers in BHJ solar cells, these CPZs improve device power conversion efficiency from 1.6% without the CPZ to 6.7-7.7% with the CPZ interlayer.
