      Cover: The image shows that CO2 molecules diffuse through cavities formed by the presence of triptycene moieties in polymers. High fractional free volume elements due to 3-dimensional rigid framework lead to high gas selectivity as well as high permeability in polymeric membranes with highly tolerant CO2 plasticization, which can be a promising membrane material for CO2 capture applications. Further information can be found in the article by Y. J. Cho, H. B. Park*on page 579.

    1. Poly(meth)acrylates Obtained by Cascade Reaction (pages 559–572)

      Dragos Popescu, Helmut Keul and Martin Moeller

      Article first published online: 31 JAN 2011 | DOI: 10.1002/marc.201000725

      Thumbnail image of graphical abstract

      In order to avoid purification and stabilization of the highly reactive functional acrylates, a concept of cascade reactions was developed comprising enzymatic monomer synthesis and free radical or nitroxide mediated radical polymerization. Hydrophilic, hydrophobic, as well as ionic repeating units were assembled within multifunctional polyacrylates suitable for versatile application.

    1. A Nanotechnology Pathway to Arresting Phase Separation in Soft Nanocomposites (pages 573–578)

      José A. Pomposo, Alaitz Ruiz de Luzuriaga, Iñaki García, Agustín Etxeberria and Juan Colmenero

      Article first published online: 27 JAN 2011 | DOI: 10.1002/marc.201000720

      A promising nanotechnology pathway: The first experimental evidence of arrested phase separation in soft nanocomposites involving ultra-small, unimolecular nanoparticles paves the way to nanocomposite materials with excellent nanoparticle dispersion across a broad temperature range.

    2. High Performance Polyimide with High Internal Free Volume Elements (pages 579–586)

      Yoon Jin Cho and Ho Bum Park

      Article first published online: 17 JAN 2011 | DOI: 10.1002/marc.201000690

      Thumbnail image of graphical abstract

      Tuning of free volume in glassy polymers: using a three-dimensional triptycene with a rigid framework and internal free volume, highly permeable, and selective polyimide membranes were developed, showing strong tolerance to CO2 plasticization, particularly for promising CO2 separation applications.

    3. Tunable Metal-Enhanced Fluorescence by Stimuli-Responsive Polyelectrolyte Interlayer Films (pages 587–592)

      Ning Ma, Fu Tang, Xiaoyu Wang, Fang He and Lidong Li

      Article first published online: 28 JAN 2011 | DOI: 10.1002/marc.201000733

      Thumbnail image of graphical abstract

      In this paper, we report on the tunable metal-enhanced fluorescence (MEF) of dendritic Ag nanostructures by the introduction of a stimulus-responsive PAA/PDDA multilayer film as an interlayer. Because of the good MEF properties of the highly dendritic nanostructures, we easily obtained an increase of up to 25 times for the weak fluorescence of porphyrin molecules (Por4–). More interestingly, the thickness of the interlayer films between the fluorophores and the Ag nanostructures could be tuned by changing the ionic strength or pH. The MEF behavior of the composite films could thus be controlled because of the distance dependent nature of the MEF effects.

    4. Enhanced Conductivity of Polyaniline by Conjugated Crosslinking (pages 593–597)

      Yuanyuan Yang, Shaozhu Chen and Lan Xu

      Article first published online: 7 MAR 2011 | DOI: 10.1002/marc.201000806

      Thumbnail image of graphical abstract

      Synthesis of covalently conjugated crosslinked PANI via chemical copolymerization of An and PPDA with TPA as a crosslinker is reported. Its structure has been characterized by spectra, and a typical four-point probe technique also used for the conductivity detection of polymer, indicating that the resulting crosslinked conjugated PANI possesses enhanced conductivity compared with the linear PANI.

    5. Electrogenerated Chemiluminescence of Pure Polymer Films and Polymer Blends (pages 598–603)

      Jiun-Tai Chen, Ya-Lan Chang, Song Guo, Omar Fabian, William M. Lackowski and Paul F. Barbara

      Article first published online: 7 MAR 2011 | DOI: 10.1002/marc.201000747

      Thumbnail image of graphical abstract

      We study electrogenerated chemiluminescence (ECL) of pure polymer films and polymer blends containing poly(9,9-dioctylfluorene-co-benzothiadiazole) (F8BT). ECL waves are triggered by leaks, which can be generated by making scratches, using thinner films, or embedding gold nanoparticles. When F8BT is blended with polystyrene (PS), a nonconjugated polymer, similar features are observed for the photoluminescence (PL) and ECL images.

    6. Continuous Controlled Radical Polymerization of Methyl Acrylate in a Copper Tubular Reactor (pages 604–609)

      Nicky Chan, Michael F. Cunningham and Robin A. Hutchinson

      Article first published online: 7 MAR 2011 | DOI: 10.1002/marc.201000786

      Thumbnail image of graphical abstract

      Continuous controlled radical polymerization of methyl acrylate at ambient temperature and at low solvent content was demonstrated in a copper tubular reactor. The copper walls provided a large surface area for catalysis and enabled fast polymerization rates. The results illustrate the significant potential of using copper tubular reactors to scale-up the production of well defined living polymer.

    7. Highly Selective Colorimetric and Fluorometric Probes for Fluoride Ions Based on Nitrobenzofurazan-containing Polymers (pages 610–615)

      Jinming Hu, Changhua Li, Yue Cui and Shiyong Liu

      Article first published online: 7 MAR 2011 | DOI: 10.1002/marc.201100024

      We report on a novel type of colorimetric and fluorometric chemosensor for fluoride ions based on nitrobenzofurazan-containing polymers, which possesses high selectivity and fluorescence “turn-off” characteristics with the detection limit down to ≈0.8µM.

    8. “Clip” and “Click” Chemistries Combination: Toward Easy PEGylation of Degradable Aliphatic Polyesters (pages 616–621)

      Hélène Freichels, Vincent Pourcelle, Cécile S. Le Duff, Jacqueline Marchand-Brynaert and Christine Jérôme

      Article first published online: 7 MAR 2011 | DOI: 10.1002/marc.201000803

      The combination of “clip” and “click” reactions provides a versatile and straightforward pathway for the synthesis of functional amphiphilic and degradable copolymers valuable for biomedical applications such as targeted drug-delivery vehicles.
