    1. Polymer Brushes by Nitroxide-Mediated Polymerization (pages 1043–1057)

      Marion K. Brinks and Armido Studer

      Version of Record online: 30 MAR 2009 | DOI: 10.1002/marc.200800720

      Surface-initiated nitroxide-mediated polymerization (NMP) has gently captured its authorization and has proven to serve as a useful tool for surface modification by thin polymer films. This article summarizes applications of NMP for the preparation of a variety of materials. Initially restricted to the formation of polystyrene brushes by using TEMPO as a regulator, development of efficient nitroxides and their applications in surface-initiated NMP allowed the preparation of various polymer brushes. Materials with interesting shapes, with macroscopic switchable properties, and with structures in the nanometer scale can be prepared.

      Frontispiece: Based on their rigid-rod structure, all-conjugated, rod-rod block copolymers prefer to self-assemble into low-curvature vesicular (or lamellar) nanostructures. This tendency should be mainly independent from the chemical structure, size, and composition of the block copolymers. The resulting materials may find application in electronic devices or artificial membranes. Further details can be found in the article by U. Scherf,* S. Adamczyk, A. Gutacker, and N. Koenen on page 1059.

      The rigid-rod structure all-conjugated, rod-rod block copolymers favour the formation of low-curvature vesicular and lamellar aggregates. The resulting nanomaterials may find applications in electronic devices or artificial membranes.

    2. Solvent Influence on Propagation Kinetics in Radical Polymerizations Studied by Pulsed Laser Initiated Polymerizations (pages 1066–1088)

      Version of Record online: 27 MAY 2009 | DOI: 10.1002/marc.200900131

      Thumbnail image of graphical abstract

      The influence of the reaction medium (organic solvents, water, ionic liquids, supercritical CO2) on the propagation rate in radical polymerizations has very different causes, e.g., hindered rotational modes, hydrogen bonding, or electron pair donor/acceptor interactions. Depending on the origin of the solvent influence propagation rate coefficients, kp, may be enhanced by up to an order of magnitude associated with changes in the pre-exponential or the activation energy of kp.

    1. UV-Responsive Behavior of Azopyridine-Containing Diblock Copolymeric Vesicles: Photoinduced Fusion, Disintegration and Rearrangement (pages 1089–1093)

      Li Lin, Zeng Yan, Junsi Gu, Yuanyuan Zhang, Ze Feng and Yanlei Yu

      Version of Record online: 20 MAY 2009 | DOI: 10.1002/marc.200900105

      Thumbnail image of graphical abstract

      Vesicles self-assembled from an azopyridine-containing amphiphilic diblock copolymer possess circular photoresponsive behavior including fusion, disintegration and rearrangement. The extent of photoinduced change can be determined by the irradiation of UV and visible light. It is possible to realize controlled release of the encapsulated substance only depending on light stimuli.

      Constructing new conjugated polymers has an important issue in polymer science. Conjugated polymers have potential applications in the optoelectronic devices because of their intriguing properties such as electrical conductivity, electroluminescence, liquid crystallinity, third-order nonlinear optical properties, and chemical sensing ability.

    3. A Novel Approach for Incorporation of Mono-Functional Bioactive Phenols into Polyanhydrides (pages 1101–1108)

      Almudena Prudencio, Ashley L. Carbone, Jeremy Griffin and Kathryn E. Uhrich

      Version of Record online: 11 MAY 2009 | DOI: 10.1002/marc.200900059

      Thumbnail image of graphical abstract

      A novel synthetic procedure that incorporates multiple bioactive molecules into the repeat unit prior to polymerization has been developed. This procedure demonstrates a new method for the incorporation of mono-functional bioactives as pendant groups to a polymer. The resulting phenolic-based polyanhydrides were proven to be noncytotoxic with favorable physiochemical characteristics for formulation into coatings or devices.

    4. Gold Nanoparticle-Hybridized “Nano-Sponge” Polymer Coatings to Enhance the Reliability and Sensitivity of Biosensors (pages 1109–1115)

      Hyung-Jun Jeong, Won-Hee Pyun and Sung Yun Yang

      Version of Record online: 11 MAY 2009 | DOI: 10.1002/marc.200900205

      We have created a new functional biosensor coating comprised of polyelectrolyte multilayers with gold nanoparticles. This gold-hybridized polyelectrolyte multilayer film possesses a stable nanoporous structure under physiological conditions. Antibody molecules were conjugated onto the gold nanoparticles of the film. This film successfully extinguished false signals from non-specific binding of proteins and provided highly enhanced detection ability.

    5. In situ Synthesis of Metal Nanoparticle Embedded Free Standing Multifunctional PDMS Films (pages 1116–1122)

      Anubha Goyal, Ashavani Kumar, Prabir K. Patra, Shaily Mahendra, Salomeh Tabatabaei, Pedro J. J. Alvarez, George John and Pulickel M. Ajayan

      Version of Record online: 2 JUN 2009 | DOI: 10.1002/marc.200900174

      Thumbnail image of graphical abstract

      A one-step method has been developed for synthesizing noble metal nanoparticle (silver, gold, platinum) embedded free standing polydimethylsiloxane (PDMS) composite films. This in situ method avoids the use of any external reducing agent/stabilizing agent and leads to a uniform distribution of nanoparticles in the PDMS matrix. The films were characterized using various techniques. The composite films show enhanced mechanical and antibacterial properties.

    6. Influence of Crystal Thickness and Topological Constraints on Chain Diffusion in Linear Polyethylene (pages 1123–1127)

      Yefeng Yao, Robert Graf, HansWolfgang Spiess and Sanjay Rastogi

      Version of Record online: 20 MAY 2009 | DOI: 10.1002/marc.200900114

      Thumbnail image of graphical abstract

      Solid-state NMR is employed to study chain diffusion between crystalline and noncrystalline regions of well-defined ultrahigh molar mass linear polyethylene. In contrast to the rate of local motions, the diffusion constant for chain translation is found to be independent of lamellar thickness. This shows that local defects are of minor importance for translation of the stems and offers a new way to determine the length of stems in ultra-drawn fibres by NMR.

    7. Oligomerization of Electron-Deficient Vinyl Monomers Through an Ate-Complex Mechanism: A New Role for B(C6F5)3 Lewis Acid (pages 1128–1132)

      B(C6F5)3 Lewis acid in combination with hydrosilanes exhibits remarkable activity in the oligomerization of sulfone and phosphonate-based vinyl monomers. This process opens new routes to high-tech silicone-based materials, i.e., thermoplastic elastomers and heat resistant polysiloxanes.
