  1. Supramolecular Adhesives to Hard Surfaces: Adhesion Between Host Hydrogels and Guest Glass Substrates Through Molecular Recognition

    Hydrogels with cyclic host molecules selectively adhere to guest molecules modified glass substrates. Adhesion depends on the affinity of guest molecules with host molecules. External stimuli regulate the adhesion between host hydrogels and guest substrates. The host molecules of the host hydrogel precisely recognize the hydrophobicity of guest molecules on the glass substrates to create an adhesive force.

  2. Stable Cross-linked Fluorescent Polymeric Nanoparticles for Cell Imaging

    Stable cross-linked fluorescent polymeric nanoparticles are facilely prepared based on an aggregation-induced emission dye via a two-step polymerization including emulsion polymerization and subsequent anhydride cross-linking. These cross-linked polymers are easy to self-assemble into uniform nanoparticles that show high water dispersibility, intense red fluorescence, and excellent biocompatibility, making them promising for cell imaging applications.

  3. Complex Macrophase-Separated Nanostructure Induced by Microphase Separation in Binary Blends of Lamellar Diblock Copolymer Thin Films

    Article first published online: 26 AUG 2014 | DOI: 10.1002/marc.201400238

    Nanostructures of thin films made of binary blends of diblock copolymers are investigated by atomic force microscopy (AFM) and grazing-incidence small-angle X-ray scattering (GISAXS). For the as-prepared thin films, microphase-separated nanostructures are obtained, and the high molar mass copolymer determines the orientation of the lamellae. After solvent vapor annealing, macrophase-separated nanostructures appear featuring parallel lamellae near the film surface and perpendicular ones in the bulk.

  4. Cu(II)-Mediated Atom Transfer Radical Polymerization of Methyl Methacrylate via a Strategy of Thermo-Regulated Phase-Separable Catalysis in a Liquid/Liquid Biphasic System: Homogeneous Catalysis, Facile Heterogeneous Separation, and Recycling

    Jinlong Pan, Bingjie Zhang, Xiaowu Jiang, Lifen Zhang, Zhenping Cheng and Xiulin Zhu

    Article first published online: 25 AUG 2014 | DOI: 10.1002/marc.201400277

    A strategy of thermo-regulated phase-separable catalysis (TPSC) is applied to the Cu(II)-mediated atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) in a p-xylene/PEG-200 biphasic system. It is a facile strategy involving successful separation and recycling of the catalyst complex from polymer products in situ. Well-defined PMMA with designable molecular weight and narrow molecular weight distribution can be obtained with this system, which may have strong potential for the industrial application of the ATRP technique.

    Back Cover: Cellulose, the most abundant terrestrial biopolymer, can be dissolved efficiently in a mixture of acetone and a quaternary ammonium chloride. The properties of the resulting translucent cellulose solution may lead to new functional cellulose derivatives or enhance shaping processes. Further information can be found in the article by Marc Kostag, Tim Liebert, and Thomas Heinze* on page 1419.
