  1. Synthesis of poly(ester-amide) dendrimers based on 2,2-Bis(hydroxymethyl) propanoic acid and glycine

    An approach for preparation of poly(ester-amide) dendrimers with hydroxyl functional groups based on 2,2-bis(hydroxymethyl) propanoic acid (bis-MPA) and glycine is presented. The applicability of these dendrimers in comparison with commercially available dendritic polymers (bis-MPA dendrimers, Hybrane S1200 hyperbranched polymer) to improve the solubility of poorly water-soluble antidiabetic drug glimepiride by preparation of solid dispersions is investigated.

  2. One donor–two acceptor (D–A1)-(D–A2) random terpolymers containing perylene diimide, naphthalene diimide, and carbazole units

    Lisa M. Kozycz, Dong Gao, Andrew J. Tilley and Dwight S. Seferos

    Article first published online: 19 SEP 2014 | DOI: 10.1002/pola.27395

    Five donor-acceptor copolymers containing various amounts of two acceptor units are synthesized by Suzuki coupling polymerization and the composition dependence of their optical and electronic properties is studied. The copolymers are tested as acceptor materials in all-polymer solar cells and the highest device efficiency is obtained for the PDI parent copolymer using PBDTTT-C as the donor material.

  3. Cu(I) camphor coordination polymers: Synthesis and study of the catalytic activity for cyclization of acid 4-pentyn-1-oic

    Tiago A. Fernandes, Adelino M. Galvão, Ana M. Botelho do Rego and M. Fernanda N. N. Carvalho

    Article first published online: 19 SEP 2014 | DOI: 10.1002/pola.27393

    The synthesis and characterization, as well as the computational optimized structural arrangement, of Cu(I) coordination polymers with camphor-derived ligands (L) having CuCl to L ratios higher (3:1 or 4:1) than the former (2:1) are reported. The compounds were shown to be active catalysts for synthesis of lactones through cyclization acid 4-pentyn-1-oic, either in solution or under solvent-free conditions. A mechanism is proposed based on calculation of constants made by fitting the 1H NMR data.

  4. Novel poly(l-lactide)/poly(d-lactide)/poly(tetrahydrofuran) multiblock copolymers with a controlled architecture: Synthesis and characterization

    Lorenza Gardella, Dario Cavallo, Samuele Colonna, Alberto Fina and Orietta Monticelli

    Article first published online: 19 SEP 2014 | DOI: 10.1002/pola.27389

    A two-stage synthetic route towards novel multiblock copolymers with a controlled architecture based on PDLA-PLLA-PTHF-PLLA-PDLA pentablock unit is developed. This approach affords materials combining the high rigidity and strength (other than improved thermal resistance) of the hard stereocomplex crystallites with the flexibility imparted by the soft block, whereby their properties can be finely tailored through the composition of the basic pentablock units without limitations on the final molecular weight.

    Orthogonal multiple click reactions in synthetic polymer chemistry

    This review highlights the concept of multiple click reaction strategy which is utilized for design and synthesis of well-defined complex macromolecular structures as well as multifunctionalization of well-defined polymers. This review examines the click combinations mainly from double to quadruple and additionally from the most frequently used to the least.
