      Front Cover: Through the use of the bulky side 1-pentylhexyloxy a soluble high molecular weight copolymer of benzo[1,2-b:4,5-b′]dithiophene and benzoxadiazole (white structure) is synthesized. The use of the the solvent additive 1-chloronapthalene greatly improves solar cell performance over those prepared from pristine solvent. Further details can be found in the article by W. Nie, C. M.

    1. RAFT Polymerization and Thiol Chemistry: A Complementary Pairing for Implementing Modern Macromolecular Design (pages 1123–1143)

      Peter J. Roth, Cyrille Boyer, Andrew B. Lowe and Thomas P. Davis

      Article first published online: 12 MAY 2011 | DOI: 10.1002/marc.201100127

      Thumbnail image of graphical abstract

      The versatility of thiol chemistry on RAFT-prepared polymers is reviewed. Methods producing stable thioether bonds as well as (bio-)degradable disulfide bonds are presented. These methods are highly useful to introduce functional or reactive end-groups into polymers and to build up (degradable) nano-structures for drug delivery purposes.

      Frontispiece: The image depicts the layer-by-layer deposition method used for building high quality homogeneous and optically transparent poly(styrene sulphonate)/TiO2 nanoparticle multilayer films on large surface areas. The photocatalytic activity of nanoporous LbL films was illustrated in a flow-reactor by the efficient removal of H2S as model odorous gas. Further details can be found in the article by D. Dontsova, V. Keller,* N. Keller, P. Steffanut, O. Félix, and G. Decher*on page 1145.

    1. Photocatalytically Active Polyelectrolyte/Nanoparticle Films for the Elimination of a Model Odorous Gas (pages 1145–1149)

      Dariya Dontsova, Valérie Keller, Nicolas Keller, Pascal Steffanut, Olivier Félix and Gero Decher

      Article first published online: 24 JUN 2011 | DOI: 10.1002/marc.201100192

      Thumbnail image of graphical abstract

      High quality homogeneous and optically transparent poly(styrene sulfonate)/titanium dioxide multilayer films are assembled on large surface areas. The nanoporous structure of such films permits access of the pollutant to catalyst surface. The photocatalytic activity of these LbL films is illustrated for the decomposition of hydrogen sulfide flow under UV-A irradiation, and compared to the activity of the original TiO2 powder.

    2. Design of Bimodal PCL and PCL-HA Nanocomposite Scaffolds by Two Step Depressurization During Solid-state Supercritical CO2 Foaming (pages 1150–1156)

      Aurelio Salerno, Stefania Zeppetelli, Ernesto Di Maio, Salvatore Iannace and Paolo Antonio Netti

      Article first published online: 3 JUN 2011 | DOI: 10.1002/marc.201100119

      Thumbnail image of graphical abstract

      The successful fabrication of bimodal porous scaffolds made of polycaprolactone (PCL) and PCL loaded with hydroxyapatite nanoparticles via the two step depressurization of solid-state supercritical CO2 foaming is reported. The entire process was performed at 37°C, so opening new routes to the design of porous bioactive scaffolds for tissue engineering.

    3. Diversified Applications of Chemically Modified 1,2-Polybutadiene (pages 1157–1162)

      Jiayin Yuan, Niels ten Brummelhuis, Mathias Junginger, Zailai Xie, Yan Lu, Andreas Taubert and Helmut Schlaad

      Article first published online: 24 JUN 2011 | DOI: 10.1002/marc.201100254

      Thumbnail image of graphical abstract

      Commercially available 1,2-polybutadiene can be readily transformed into either a multifunctional macroinitiator or a reactive and ion conductive polyelectrolyte. The aim of the work is to broaden the application spectrum of polybutadiene, which is often considered as a “normal and traditional” polymer.

    4. A Soluble High Molecular Weight Copolymer of Benzo[1,2-b:4,5-b′]dithiophene and Benzoxadiazole for Efficient Organic Photovoltaics (pages 1163–1168)

      Wanyi Nie, Christopher M. MacNeill, Yuan Li, Ronald E. Noftle, David L. Carroll and Robert. C. Coffin

      Article first published online: 10 JUN 2011 | DOI: 10.1002/marc.201100161

      Thumbnail image of graphical abstract

      The use of the bulky side chain, 1-pentylhexyloxy at the 4 and 8 positions of benzo[1,2-b:4,5-b′]dithiophene allows for the synthesis of a high molecular weight, soluble copolymer with 2,1,3-benzoxadiazole. The high molecular weight and solubility allows for the preparation of organic solar cells with power conversion efficiencies near 6% when additive processing is employed.

    5. Aptamers-in-Liposomes for Selective and Multiplexed Capture of Small Organic Compounds (pages 1169–1173)

      Yeon Seok Kim, Javed H. Niazi, Yun Ju Chae, U-Ri Ko and Man Bock Gu

      Article first published online: 11 JUL 2011 | DOI: 10.1002/marc.201100177

      Thumbnail image of graphical abstract

      Aptamer-in-liposome composites are designed and fabricated successfully for three different model aptamers for selective capture of three different target molecules independently or together. This composite of aptamers and liposomes provides a new feature in maintaining the aptamer performance, even in unbuffered samples, and can be applied in selective capture or recovery of target molecules.

    6. Spiropyran-Based Polymeric Vesicles: Preparation and Photochromic Properties (pages 1174–1179)

      Chuan-Qun Huang, Ying Wang, Chun-Yan Hong and Cai-Yuan Pan

      Article first published online: 10 JUN 2011 | DOI: 10.1002/marc.201100197

      Thumbnail image of graphical abstract

      A facile method for one-pot synthesis of functional polymeric nanomaterials based on controlled radical polymerization is developed. Photochromic vesicles formed by P(4VP-co-SPMA)-b-PS were produced via PISR method through RAFT dispersion polymerization of St. In comparison to free polymer chains in DMF, the vesicles solution exhibited stronger fluorescence, excellent reversibility, and stability.

    7. Step-Growth Radical Addition-Coupling Polymerization (RACP) for Synthesis of Alternating Copolymers (pages 1180–1184)

      Chengyu Zhang and Qi Wang

      Article first published online: 3 JUN 2011 | DOI: 10.1002/marc.201100208

      Thumbnail image of graphical abstract

      We develop a new type of step-growth radical addition-coupling polymerization (RACP) involving consecutive addition of carbon-centered radical derived from α,α′-dibromo dibasic ester to NO double bond of C-nitroso compound followed by cross-coupling of carbon-centered radical and in situ formed nitroxyl radical, which produces alternating copolymers with high molecular weight and unimodal molecular weight distribution from saturated and unsaturated monomers.

    8. Thermosensitivity of Bile Acid-Based Oligo(ethylene glycol) Stars in Aqueous Solutions (pages 1185–1189)

      Satu Strandman, Frantz Le Dévédec and X. X. Zhu

      Article first published online: 10 JUN 2011 | DOI: 10.1002/marc.201100234

      Thumbnail image of graphical abstract

      Thermosensitivity of bile acid-based star-shaped oligo(ethylene glycol)s depends on the number of PEG arms. The grafting of two oligo(ethylene glycol) chains on a lithocholic acid core renders the polymer a “double thermosensitivity” arising from the LCST of PEGs and the temperature-responsive self-assembly of the bile acid derivative. The addition of salt has different effects on the two-phase transitions.

      Article first published online: 24 JUN 2011 | DOI: 10.1002/marc.201100214

      This study highlights the great potential of simple polymers as sensitizer for dye-sensitized solar cells once they are functionalized by a suitable anchoring group.

    10. Synthesis of Poly(anilineboronic acid) Nanofibers for Electrochemical Detection of Glucose (pages 1195–1199)

      Article first published online: 20 JUN 2011 | DOI: 10.1002/marc.201100232

      Thumbnail image of graphical abstract

      Poly(anilineboronic acid) nanofibers with controllable morphologies have been fabricated by chemical polymerization of 3-aminophenylboronic acid in the presence of cetyltrimethylammonium bromide and NaF. The PABA nanofibers exhibit excellent electrochemical redox activity and high sensitive detection of D-glucose in the phosphate-buffered saline stock solution (pH 7.4).
