  1. Photoluminescent Nematic Liquid Crystalline Elastomer with a Thermomechanical Emission Variation Function

    Renbo Wei, Yaning He, Xiaogong Wang and Patrick Keller

    Article first published online: 31 JUL 2014 | DOI: 10.1002/marc.201400264

    Nematic liquid crystalline elastomer (LCE) microactuators with simultaneous thermomechanical deformation and photoluminescence emission variation functions are developed. During the heating process, the PL emission of the LCE micropillars under blue light excitation is observed to become significantly weak when the micropillars contracted at TNI. When cooling down, the emission completely recovers as the micropillars stretched back to their original shape.

  2. Highly Sensitive Dual-Mode Fluorescence Detection of Lead Ion in Water Using Aggregation-Induced Emissive Polymers

    Sukanta Kumar Saha, Khama Rani Ghosh, Jian Ping Gao and Zhi Yuan Wang

    Article first published online: 31 JUL 2014 | DOI: 10.1002/marc.201400254

    A series of fluorene-based conjugated polymers containing the aggregation-induced emissive-active tetraphenylethene and dicarboxylate pseudocrown as a receptor exhibits a unique dual-mode sensing ability for selective detection of lead ion in water with a concentration as low as 10−8 M.

  3. A Supramolecular Strategy for Self-Mobile Adsorption Sites in Affinity Membrane

    Ligang Lin, Meimei Dong, Chunyu Liu, Chenjie Wei, Yuanyuan Wang, Hui Sun and Hui Ye

    Article first published online: 30 JUL 2014 | DOI: 10.1002/marc.201400289

    Enhanced sites working efficiency: A novel supramolecular membrane with self-mobile adsorption sites is designed for biomolecules purification. The polyrotaxanes with mobile sites provide supramolecular atmosphere, and the abundant pores in membrane matrix provide 3D channels for efficient work. During membrane filtration, the sites can rotate and/or slide along the axial chain, which results in the enhanced adsorption performance.

  4. Shape Memory Particles Capable of Controlled Geometric and Chemical Asymmetry made from Aliphatic Polyesters

    Sarah M. Brosnan, Anne-Martine S. Jackson, Yapei Wang and Valerie Sheares Ashby

    Article first published online: 24 JUL 2014 | DOI: 10.1002/marc.201400199

    A novel technique for creating monodisperse shape memory particles is reported. A soft mold is used to uniformly deform particles of complex shapes to other well-defined shapes, harvest them without aggressive solvents or heat, and then return them to their original shapes upon heating above a preselected triggering temperature. Particles are synthesized from a broad range of materials and additionally are capable of both chemical and physical asymmetry.

  5. Preparation of Core–Shell Nanofibers with Selectively Localized CNTs from Shish Kebab-like Hierarchical Composite Micelles

    Chang-Lei Liu, Mei-Jia Wang, Gang Wu, Jiao You, Si-Chong Chen, Ya Liu and Yu-Zhong Wang

    Article first published online: 22 JUL 2014 | DOI: 10.1002/marc.201400261

    A novel and facile bottom-up strategy is described for preparing core–shell nanofibers with selectively localized carbon nanotubes by using hierarchical composite micelles of crystalline-coil copoly­mer and CNTs as the building blocks.
