    Poly(l-lactide) (PLLA) modified by a room-temperature ionic liquid (IL) is studied and results show that crystalline morphology of PLLA is significantly changed by IL to display massive diversification of spherulite morphology. The diversified spherulite patterns in PLLA/IL mixtures are assocaited wtih strong interactions, which impede crystallization of PLLA and tend to form nuclei of various geometry shapes.

  2. Facile Route for the Synthesis of Adamantane-Containing Polypeptides through Polycondensation of Activated Urethane Derivative of α-Amino Acids

    Facile synthesis of polypeptide bearing adamantane in the side chain has been developed through polycondensation of N-phenoxylcarbonyl derivative of α-amino acid with the elimination of phenol and CO2. Heating the urethane derivative at 60 °C using n-butylamine and poly(ethylene glycol) with the terminal amino group as an initiator gave the well-controlled polypeptide in terms of mole­cular weigh and terminal structure.

  3. Rigid-Rod Polyamides from 3,3′-bis­(trifluoromethyl)-4,4′-diamino-1,1′-biphenyl

    Sun Dal Kim, Taejoon Byun, Byungyong Lee, Sang Youl Kim and Im Sik Chung

    Article first published online: 6 MAY 2015 | DOI: 10.1002/macp.201500013

    A series of rigid-rod polyamides with trifluoromethyl pendant groups are prepared via polycondensation of the diamine monomer and diacid chlorides. Synthesized polyamides are colorless and possess good thermal stabilities owing to the incorporation of trifluoromethyl pendant groups. The meta-linked polyamide shows good solubility in organic solvent whereas the para-linked one exhibits limited solubility.

  4. Click Functionalization of Aromatic Polymers for Organic Electronic Device Applications

    Article first published online: 5 MAY 2015 | DOI: 10.1002/macp.201500086

    Optical and electrochemical properties of aromatic polymers are tuned by the novel click reactions using cyano-acceptor reagents. The resulting polymers contain donor–acceptor chromophores and accordingly can be applied to organic electronic devices including thin film transistors, organic solar cells, and polymer memory devices. A series of device studies reveal the characteristic electronic features of the formed donor-acceptor chromophores.

    Front Cover: Novel, pyrene-functionalized styrene polymers (P7–9) and thiophene compound (Thi-Pyr) are prepared via click-chemistry techniques. Under UV light, the compounds fluoresce with blue and greenish-blue light respectively, with Thi-Pyr exhibiting the characteristic pyrene monomer emission bands, while P7–9 show the excimer emission bands of pyrene due to the excitation of ground state dimeric species. These compounds are employed as optical chemical probes for qualitative ion sensing via fluorescence spectroscopy. Further details can be found in the article by O. Karagollu, M. Gorur, F. Gode,* B. Sennik, and F. Yilmaz* on page 939.
