      Cover: Polymer bearing anilide groups were used to create fluorescent micropatterns in a thin polymer film. The fluorescamine-treated irradiated polymer film showed strong fluorescence in the range of 420 ∼ 620 nm. The fluorescent micropatterns appeared in a wide range of colors from dark-blue to yellow depending on the observation wavelength ranges. Further details can be found in the article by K. H. Chae,* and S. J. Baek on page 1190.

    1. Chemical Routes Toward Multicompartment Colloids (pages 1183–1189)

      Daniel Crespy, Roland Hinrich Staff, Tanja Becker and Katharina Landfester

      Version of Record online: 11 MAY 2012 | DOI: 10.1002/macp.201200124

      Complex colloidal structures can be elaborated via a cornucopia of synthetic pathways. The different routes are classified in: assembly of colloids, synthesis with the use of sacrificial templates, and internal phase separation in colloidal droplets. A tentative analogy between the basic arithmetic operations and these routes is proposed.

    1. Fluorescence Micropatterning by the Photo-Anilide Rearrangement of Polymer Bearing Anilide Groups (pages 1190–1195)

      Kyu Ho Chae and Sun Jung Baek

      Version of Record online: 21 MAY 2012 | DOI: 10.1002/macp.201200207

      Thumbnail image of graphical abstract

      Polymer bearing anilide groups were used to create fluorescent micropatterns. Polymer bearing anilide groups underwent photo-anilide rearrangement. The fluorescamine-treated irradiated polymer film showed strong fluorescence in the range of 420∼620 nm. The fluorescent micropatterns appeared in a wide range of colors depending on the observed wavelength ranges.

    2. Optimizing Noncovalent Interactions Between Lignin and Synthetic Polymers to Develop Effective Compatibilizers (pages 1196–1205)

      Nathan Henry, David Harper and Mark Dadmun

      Version of Record online: 11 MAY 2012 | DOI: 10.1002/macp.201100633

      Lignin is an abundant natural material that is the derivative of a number of high-volume processes, including papermaking and the formation of biofuels. Effective compatibilizers of lignin with styrenic polymers are identified in this work, and guidelines are presented that enable the design of effective polymeric interfacial modifiers that efficiently interact with the naturally derived macromolecules.

    3. On The Incompatibility of Dextran and Pullulan in Aqueous Solutions and Its Modeling (pages 1206–1215)

      Anja Eckelt, John Eckelt, Wolfgang Schärtl and Bernhard A. Wolf

      Version of Record online: 9 MAY 2012 | DOI: 10.1002/macp.201200040

      Despite the evident chemical similarity of the polysaccharides dextran and pullulan these polymers are incompatible in water. The experimental observations can be modeled by means of concentration-dependent binary interaction parameters on the basis of an approach accounting for chain connectivity and conformational relaxation of the components.

    4. The Use of Cyclopenta[2,1-b;3,4-b′]dithiophene Analogues for the Development of Low-Bandgap Materials (pages 1216–1224)

      Pieter Willot, Lieven De Cremer and Guy Koeckelberghs

      Version of Record online: 19 APR 2012 | DOI: 10.1002/macp.201200050

      Thumbnail image of graphical abstract

      An alternative method towards low-bandgap materials is presented. A low-energy absorption band is observed due to a localized transition within electron-poor cyclopenta[2,1-b;3,4-b′]dithiophene-based molecules. The most important factor determining the bandgap is the type of electron-withdrawing group. Therefore, the resulting bandgap can easily be tuned by substituent selection.

    5. Liquid–Liquid Extraction of 3FOx and 5FOx Polyoxetane Diols: Impact on Polyurethane Mechanical Properties, Surface Morphology, and Wetting Behavior (pages 1225–1238)

      Wei Zhang, Daniel Henke, David Presnall, Souvik Chakrabarty, Chenyu Wang and Kenneth J. Wynne

      Version of Record online: 19 APR 2012 | DOI: 10.1002/macp.201200053

      Thumbnail image of graphical abstract

      Guided by phase diagrams, laboratory prepared and commercial poly(2-2,2,2-trifluoroethoxy-2-methyl)oxetane, P[3FOx] and poly(2-2,2,2-pentafluoropropoxy-2-methyl)oxetane, P[5FOx] diols were separated/purified. Characterization of derived polyurethanes utilized GPC, mechanical tests, AFM, and DCA.

    6. Banded Spherulitic Morphology in Blends of Poly (propylene fumarate) and Poly(ϵ-caprolactone) and Interaction with MC3T3-E1 Cells (pages 1239–1250)

      Kan Wang, Stephen Jesse and Shanfeng Wang

      Version of Record online: 20 APR 2012 | DOI: 10.1002/macp.201200004

      Thumbnail image of graphical abstract

      The thermal properties, crystallization behavior, and miscibility of isothermally crystallized blends of biodegradable poly(propylene fumarate) and poly(ϵ-caprolactone) are investigated and it is studied how these crystallization-induced surface morphologies influence hydrophilicity, protein adsorption, cell attachment, spreading, and proliferation.

    7. Graphene Network Organisation in Conductive Polymer Composites (pages 1251–1258)

      Yuliya V. Syurik, Marcos G. Ghislandi, Evgeniy E. Tkalya, Garry Paterson, Damian McGrouther, Oleg A. Ageev and Joachim Loos

      Version of Record online: 30 APR 2012 | DOI: 10.1002/macp.201200116

      Thumbnail image of graphical abstract

      Graphene forms different networks in the volume of PS and PP matrixes, which are visualised by means of SEM and confirmed by electrical conductivity measurements performed in various directions. The different network organisation can be explained by the different flow and crystallisation behaviour of the polymer matrixes during processing.

    8. Imidazolium End-Functionalized ATRP Polymers as Directing Agents for CNT Dispersion and Confinement (pages 1259–1265)

      Bart Dervaux, Franck Meyer, Jean-Marie Raquez, Aurore Olivier, Filip E. Du Prez and Philippe Dubois

      Version of Record online: 20 APR 2012 | DOI: 10.1002/macp.201200103

      Imidazolium end-functionalized (co)polymers are synthesized via ATRP. In solution, the polymers demonstrate a high binding ability toward CNTs. Careful selection of the ω-imidazolium polymer allows to control the CNT confinement toward a specific polymer phase within polymer mixtures.

      Wen-Hua Sun, Weizhen Zhao, Jiangang Yu, Wenjuan Zhang, Xiang Hao and Carl Redshaw

      Version of Record online: 20 APR 2012 | DOI: 10.1002/macp.201200051

      Iron complexes bearing unsymmetrical bis(imino)pyridine ligands are synthesized and fully characterized. Upon activation with MMAO, all iron precatalysts exhibit high activity in ethylene polymerization, producing highly linear polyethylenes.

    10. New Functional Block Copolymers via RAFT Polymerization and Polymer-Analogous Reaction (pages 1274–1284)

      Oliver I. Strube, Lars Nothdurft, Zaure Abisheva and Gudrun Schmidt-Naake

      Version of Record online: 30 APR 2012 | DOI: 10.1002/macp.201200026

      Functional triblock copolymers can not easily be prepared by conventional polymerization. Here, the synthesis of a variety of partially functional triblock copolymers by combined RAFT polymerization and polymer-analogous reaction is reported. The polymers are analyzed via FTIR, elemental analysis, and MALDI-TOF MS. The efficiencies of the different polymer-analogous reactions are compared.

    11. Direct Nanopatterning Into Conjugated Polymers Using Interference Crosslinking (pages 1285–1290)

      Xinping Zhang, Hongmei Liu, Hongwei Li and Tianrui Zhai

      Version of Record online: 30 APR 2012 | DOI: 10.1002/macp.201200066

      Thumbnail image of graphical abstract

      A direct nanopatterning technique is described that includes exposing a thin film of conjugated polymers to the interference pattern of UV laser beams. The polymer molecules become crosslinked in bright fringes, leading to nanoscale periodic modulation both in refractive index and thickness. A plastic photonic device is thus obtained with excellent microscopic and spectroscopic properties.
