  1. Temperature-Triggered Phase Separation of a Hydrophilic Resilin-Like Polypeptide

    Linqing Li, Tianzhi Luo and Kristi L. Kiick

    Article first published online: 26 NOV 2014 | DOI: 10.1002/marc.201400521

    Hydrophilic resilin-like polypeptides: solutions of recombinant resilin-like polypeptides exhibit phase separation and form nanoparticles with increasing temperatures. The transition temperature and particles sizes can be modulated via salt identity, ionic strength, pH, and denaturants.

  2. Star-Pseudopolyrotaxane Organized in Nanoplatelets for Poly(ε-caprolactone)-Based Nanofibrous Scaffolds with Enhanced Surface Reactivity

    Murielle Oster, Anne Hébraud, Sébastien Gallet, Alain Lapp, Eric Pollet, Luc Avérous and Guy Schlatter

    Article first published online: 25 NOV 2014 | DOI: 10.1002/marc.201400533

    Star pseudopolyrotaxanes of α-cyclodextrin and star poly(ε-caprolactone) form stable nanoplatelet micelles in dimethyl sulf­oxide and are subsequently processed by coaxial electrospinning to obtain poly(ε-caprolactone):star pseudopolyrotaxanes core:shell fibers. The star pseudopolyrotaxanes shell ensures the presence of α-cyclodextrin hydroxyl functions on the fiber surface allowing efficient postfunctionalization while keeping intact the entire morphology of the fibrous scaffold in solvents.

  3. Design of Smart Oligo(ethylene glycol)-Based Biocompatible Hybrid Microgels Loaded with Magnetic Nanoparticles

    Mohamed Boularas, Emilie Gombart, Jean-François Tranchant, Laurent Billon and Maud Save

    Article first published online: 25 NOV 2014 | DOI: 10.1002/marc.201400578

    Smart biocompatible oligo(ethylene glycol)-based hybrid microgels loaded with a high content of homogeneously distributed preformed magnetic nanoparticles are synthesized by a simple two-step method. The monodisperse thermoresponsive magnetic microgels exhibit a constant value of the volume phase transition temperature up to high nanoparticle (NP) content (33 wt%) thanks to the homogeneous microstructure of the initial biocompatible microgels.

  4. Pillar[10]arene-Based Size-Selective Host–Guest Complexation and Its Application in Tuning the LCST Behavior of a Thermoresponsive Polymer

    Guocan Yu, Jiong Zhou and Xiaodong Chi

    Article first published online: 25 NOV 2014 | DOI: 10.1002/marc.201400570

    A water soluble pillar[10]arene-based size selective host–guest complexation is investigated, which can be further utilized to tune the LCST (lower critical solution temperature) behavior of a thermoresponsive random copolymer. Due to the suitable size of the 1,10-phenanthrolinium guest (G), pillar[10]arene exhibits a much higher binding affinity with G than that with paraquat, which is mainly driven by the cooperativity of multiple electrostatic interactions, hydrophobic interactions, and π–π stacking interactions.

  5. High-Efficiency Large-Bandgap Material for Polymer Solar Cells

    Hedi Wei, Yi-Hsiang Chao, Chong Kang, Cuihong Li, Heng Lu, Xue Gong, Huanli Dong, Wenping Hu, Chain-Shu Hsu and Zhishan Bo

    HD-PDFC-DTBT with a large bandgap of 1.96 eV is synthesized and used for the fabrication of polymer solar cells (PSCs). A power conversion efficiency (PCE) of 7.39% with a Voc of 0.93 V, a Jsc of 14.11 mA cm−2, and an FF of 0.56 is obtained in inverted PSCs with (6,6)-phenyl-C71-butyric acid methyl ester (PC71BM) as the acceptor without using any processing additive.
