  1. Functionalized PEG-b-PAGE-b-PLGA triblock terpolymers as materials for nanoparticle preparation

    Justyna A. Czaplewska, Tobias C. Majdanski, Markus J. Barthel, Michael Gottschaldt and Ulrich S. Schubert

    The poly(ethylene glycol)-block-poly(allyl glycidyl ether) as well as their copolymers with poly(lactide-co-glycolide) are prepared by introduction of a primary OH group and subsequent ring-opening polymerization. The polymers are further functionalized via thiol-ene reaction. Spherical particles with diameters around 200 nm and a relatively low PDIparticle value of 0.03–0.1 could be obtained from the functional amphiphilic block copolymers (DLS and SEM). The obtained nanoparticles represent promising candidates for drug delivery studies.

    Ru(II)(Tpy)2-functionalized hydrogels are designed and prepared, the reversible redox responsiveness of the synthetic hydrogels is investigated, the occurrence of the BZ reaction in the hydrogel networks is demonstrated, and the self-oscillating properties of the BZ reaction are studied.

  3. Norbornene derivatives from a metal-free, strain-promoted cycloaddition reaction: New building blocks for ring-opening metathesis polymerization reactions

    Christopher E. Hobbs, Binhong Lin and Thomas Malinski

    Article first published online: 21 MAY 2015 | DOI: 10.1002/pola.27691

    A facile 1,3-dipolar cycloaddition between azides and norbornadiene is used for the preparation of new monomers for ring-opening metathesis polymerization (ROMP) reactions. These species can be obtained under solvent-and catalyst-free reaction conditions and copolymerized with other norbornenes to provide new, functionalized polymers. Further polymer functionalization can be obtained through a thermal loss of N2.

  4. Novel chiral PEDOTs for selective recognition of 3,4-dihydroxyphenylalanine enantiomers: Synthesis and characterization

    This article reports two novel compounds of side-chain functionalized 3,4-ethylenedioxythiophenes (EDOTs), that is, (2R)-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methyl 2-phenylpropanoate ((R)-EDTM-PP) and (2S)-(2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methyl 2-phenylpropanoate ((S)-EDTM-PP). The new compounds can be employed as chiral electrodes to successfully recognize 3,4-dihydroxyphenylalanine (DOPA) enantiomers.

  5. Synthesis and characterization of benzimidazolium-functionalized polysulfones as anion-exchange membranes

    A series of benzimidazolium-functionalized polysulfones were synthesized and characterized. The electrochemical behavior of the resulting anion-exchange membranes showed a clear dependence with the degree of chloromethylation of polysulfone. Thus, the ionic conductivity increased more than two orders of magnitude when the degree of chloromethylation increased from 40 to 140%. In addition, the presence of benzimidazolium groups instead of the widely used quaternary ammonium ones improved the ionic conductivity of the polymeric membranes.
