  1. Dynamic covalent polypeptides showing tunable secondary structures and thermoresponsiveness

    The imine condensation from poly(l-lysine)s and oligoethylene glycol (OEG)-based dendritic aldehydes afforded dynamic OEGylated polypeptides, which show enhanced helical conformation and superior thermoresponsive properties. Their phase transition temperatures were governed predominately by terminal groups and coverage of OEG dendrons, and could be tuned simply by varying ratios of OEG dendrons with different hydrophilicity. Furthermore, thermally induced dehydration and aggregation was found to enhance the imine formation and, at the same time, to switch helical conformations of polypeptides.

  2. Synthesis via ATRP, kinetics study and characterization (molecular-morphological) of 3-Arm star diblock copolymers of the (PS-b-P2VP)3 type

    The successful synthesis via ATRP of 3-arm star homopolymers and corresponding diblock copolymers of the (PS)3 and (PS-b-P2VP)3 types, through an initiator bearing three –Br groups, is discussed. A kinetics study is performed for the synthesis of the star homopolymer to evaluate polymerization time versus polydispersity, molecular weight, and yield. Molecular characterization through various techniques verifies the preparation of both architectures and TEM studies confirm the microphase separation of the final copolymers.

  3. RAFT polymerization kinetics and polymer characterization of P3HT rod–coil block copolymers

    Melissa R. Kern and Stephen G. Boyes

    Article first published online: 18 OCT 2014 | DOI: 10.1002/pola.27425

    The reversible addition–fragmentation chain transfer (RAFT) polymerization kinetics using a poly(3-hexylthiophene) (P3HT) macroRAFT agent, in which the P3HT is incorporated into the R group of the RAFT agent, are reported.

  4. Thieno[3,2-b]thiophene-substituted benzodithiophene in donor–acceptor type semiconducting copolymers: A feasible approach to improve performances of organic photovoltaic cells

    Ji-Hoon Kim, Hee Su Kim, Jong Baek Park, In-Nam Kang and Do-Hoon Hwang

    Article first published online: 18 OCT 2014 | DOI: 10.1002/pola.27431

    New D-A type copolymer (PTTBDT-TPD) consisting of TTBDT and thieno[3,4-c]pyrrole-4,6-dione (TPD) is synthesized by Stille-coupling polymerization. A PTTBDT-TPD analog consisting of TTBDT and alkylthienyl-substituted BDT (PTBDT-TPD) is also synthesized to compare the optical, electrochemical, morphological, and photovoltaic properties of the polymers.

  5. Synthesis of Pyridine Chitosan and its Protonic Conductivity
