  1. Synthesis of optically active conjugated polymers containing platinum in the main chain: Control of the higher-order structures by substituents and solvents

    Yu Miyagi, Takehiro Hirao, Takeharu Haino and Fumio Sanda

    Article first published online: 3 AUG 2015 | DOI: 10.1002/pola.27759

    Novel optically active poly(phenyleneethynylene)s bearing platinum in the main chain were synthesized by the Sonogashira–Hagihara coupling polymerization of amino acid based optically active diiodoareylene monomers with a platinum-containing diethynyl monomer. Solvent effects on the higher-order structures were examined.

  2. PNVCL-PEGMA nanohydrogels with tailored transition temperature for controlled delivery of 5-fluorouracil

    Article first published online: 3 AUG 2015 | DOI: 10.1002/pola.27766

    Preparation of N-vinylcaprolactam-based nano(hydro)gels without the use of emulsion stabilizers is demonstrated by means of surfactant free emulsion polymerization. Methacrylate functionalized polyethyleneglycol was used to provide the nanomaterials with a biocompatible, immune system “invisible,” shell. Two comonomers were incorporated to increase the transition temperature (Ttr): N-vinylpirrolidone (Ttr = 42 °C) and 2-methacryloyloxy benzoic acid (Ttr= 38 °C). The so tailored nano(hydro)gels showed faster release of the anticancer drug 5-fluorouracil at tumor conditions.

  3. Effect of side chain conjugation lengths on photovoltaic performance of two-dimensional conjugated copolymers that contain diketopyrrolopyrrole and thiophene with side chains

    Article first published online: 3 AUG 2015 | DOI: 10.1002/pola.27767

    Two new 2D conjugated copolymers, called PDPPMTD and PDPPBTD, were designed and synthesized for use in PSCs. The findings herein suggest that the subtle tuning of the chemical structure of the side chains appeared significantly to influence the Jsc and FF.

  4. Azide-functionalized nanoparticles as quantized building block for the design of soft–soft fluorescent polystyrene core—PAMAM shell nanostructures

    Krystyna Baczko, Hélène Fensterbank, Bruno Berini, Nadège Bordage, Gilles Clavier, Rachel Méallet-Renault, Chantal Larpent and Emmanuel Allard

    Article first published online: 3 AUG 2015 | DOI: 10.1002/pola.27772

    This work reports the covalent association of azido-coated nanoparticles, amino-terminated PAMAM dendrons, and a Bodipy derivative that leads to well-defined fluorescent dendrimer-based nanostructures in the 20–30 diameter range. These nano-objects display absorption and emission maxima above 500 nm with brightness the same order of magnitude as Qdots.

  5. Effect of limonene on the frontal ring opening metathesis polymerization of dicyclopentadiene

    Valeria Alzari, Daniele Nuvoli, Davide Sanna, Andrea Ruiu and Alberto Mariani

    Article first published online: 3 AUG 2015 | DOI: 10.1002/pola.27776

    Frontal ring opening metathesis polymerization was successfully applied to the synthesis of copolymers of dicyclopentadiene and limonene. The presence of limonene was found to be crucial for many polymerization parameters and confers new and particular characteristics to polymer materials.
