      Front Cover: A polymer microsphere, crosslinked and functionalized by amine, can be used as a solid-state template for the synthesis of gold (Au) crystals in the form of either nanoparticles (NPs) or plates. The polymer microsphere acts as an internal template to cultivate Au NPs inside the microsphere or an external template to generate the singlecrystal plates depending on the critical concentration of gold ions. Further details can be found in the article by J. S. Oh, L. N. Dang, S. W. Yoon, P. C. Lee, D. O. Kim, K. J. Kim, and J. D. Nam* on page 504.

    1. Controlling the Pore Sizes and Related Properties of Inverse Opal Scaffolds for Tissue Engineering Applications (pages 485–491)

      Yu Shrike Zhang, Kevin P. Regan and Younan Xia

      Version of Record online: 31 JAN 2013 | DOI: 10.1002/marc.201200740

      Thumbnail image of graphical abstract

      Inverse opal scaffolds with precisely controlled window size, surface pore size, and bulk pore size are fabricated to investigate the effects of these parameters on their mechanical properties and cell penetration. These results can provide important guidelines for the future design of three-dimensional porous scaffolds for tissue engineering and regenerative medicine applications.

    2. Conjugated Polymer Chains Confined in Vertical Nanocylinders of a Block-Copolymer Film: Preparation, Characterization, and Optoelectronic Function (pages 492–497)

      Ban Xuan Dong, Yoshihiro Honmou, Hideaki Komiyama, Shu Furumaki, Tomokazu Iyoda and Martin Vacha

      Version of Record online: 15 JAN 2013 | DOI: 10.1002/marc.201200766

      Thumbnail image of graphical abstract

      Hybrid materials composed of a phase-separated block copolymer and oriented chains of phenylenevinylene (PPV) family polymers are reported. Confinement of the PPV chains into vertical cylinders of nanometer diameter results in large absorption anisotropy. The hybrid films show electroluminescence from the PPV chains at minute doping concentrations and exhibit increased electron transport along the single PPV chains.

    3. A Polymer Network Prepared by the Thiol-yne Photocrosslinking of a Liquid Crystalline Dendrimer (pages 498–503)

      Ramón Cervera-Procas, Carlos Sánchez-Somolinos, José L. Serrano and Ana Omenat

      Version of Record online: 16 JAN 2013 | DOI: 10.1002/marc.201200730

      Thumbnail image of graphical abstract

      Easy to process polymeric materials may be prepared by the photocrosslinking of multifunctional dendrimers. A liquid crystalline dendrimer bearing azobenzene groups and alkyne-terminated units are photopolymerized with a tetrathiol agent to afford an oriented polymer film, which maintains the liquid crystalline order and responds to the light suffering a photoinduced deformation.

    4. Amine-Functionalized Polyglycidyl Methacrylate Microsphere as a Unified Template for the Synthesis of Gold Nanoparticles and Single-Crystal Gold Plates (pages 504–510)

      Joon Suk Oh, Luong Nguyen Dang, Sung Woon Yoon, Pyoung Chan Lee, Dong Ouk Kim, Kwang Jin Kim and Jae Do Nam

      Version of Record online: 25 JAN 2013 | DOI: 10.1002/marc.201200713

      Thumbnail image of graphical abstract

      Functionalized polymer microspheres are employed as solid-state templates for the synthesis of gold nanocrystals. It is discovered that the microsphere acts as either an internal or external template depending on the critical concentration of gold ions to generate gold nanoparticles or plates inside or outside the microsphere.

    5. The Pt-Organometallic Version of Perigraniline: Going Blue (pages 511–515)

      Tommy Kenny, Shawkat M. Aly, Gessie Brisard, Daniel Fortin and Pierre D. Harvey

      Version of Record online: 25 JAN 2013 | DOI: 10.1002/marc.201200741

      Thumbnail image of graphical abstract

      The poly (trans-bis(phenylacetylene)bis (tributylphosphine) platinum(II)anthraquinone)s exhibit completely unexpected blue-shifted charge-transfer absorption bands and more negative reduction potentials in comparison with the quinone diimine analogues. This is caused by intramolecular steric hindrance between the phenyl and anthraquinone groups.

    6. Toward Photopatternable Thin Film Optical Sensors Utilizing Reactive Polyphenylacetylenes (pages 516–521)

      Anja C. Pauly and Patrick Theato

      Version of Record online: 30 JAN 2013 | DOI: 10.1002/marc.201200764

      Thumbnail image of graphical abstract

      Reactive substituted polyphenylacetylenes (PPAs), which can be used for patterned films for optical sensors, are synthesized. PPAs featuring reactive pentafluorophenyl (PFP) ester moieties are modified, enabling crosslinking upon irradiation. Photopatterned thin films still contain PFP ester moieties for a subsequent modification resulting in a color change of the films.

    7. Modular Establishment of a Diketopyrrolopyrrole-Based Polymer Library via Pd-Catalyzed Direct C–H (Hetero)arylation: a Highly Efficient Approach to Discover Low-Bandgap Polymers (pages 522–527)

      Qiang Guo, Jiaxing Dong, Danyang Wan, Di Wu and Jingsong You

      Version of Record online: 31 JAN 2013 | DOI: 10.1002/marc.201200737

      Thumbnail image of graphical abstract

      A concise, highly efficient direct C–H (hetero)arylation polycondensation is used as a powerful tool to assemble a structurally diverse DTDPP-based polymer library to screen near-infrared absorbing polymers. A series of polymers exhibit low bandgaps (down to 1.22 eV) as well as strong and broad absorption bands (up to 1000 nm).

    8. Reactive Template Synthesis of Polypyrrole Nanotubes for Fabricating Metal/Conducting Polymer Nanocomposites (pages 528–532)

      Jun Zhang, Xianghong Liu, Lixue Zhang, Bingqiang Cao and Shihua Wu

      Version of Record online: 23 JAN 2013 | DOI: 10.1002/marc.201200757

      Thumbnail image of graphical abstract

      Polypyrrole (PPy)/Au and PPy/Pt hybrid nanotubes are fabricated by a facile solution reduction procedure using PPy nanotubes as the support. The conducting polymer PPy nanotubes are synthesized by templating against MnO2 nanowires. The metal content in the nanocomposites can be tuned by simply changing the amount of metal precursor. This work provides an efficient and general approach to metal/conducting polymer hybrid nanotubes that are potentially useful for electrocatalyst and sensor materials.

    9. Generation of Ultra-High-Molecular-Weight Polyethylene from Metallocenes Immobilized onto N-Doped Graphene Nanoplatelets (pages 533–538)

      Baekhap Choi, Juno Lee, Seungjun Lee, Jae-Hyeon Ko, Kyoung-Seok Lee, Junghoon Oh, Jongwoo Han, Yong-Hyun Kim, Insung S. Choi and Sungjin Park

      Version of Record online: 25 JAN 2013 | DOI: 10.1002/marc.201200768

      Thumbnail image of graphical abstract

      Ultra-high-molecular-weight polyethylenes are produced from the polymerizations using group 4-based metallocenes immobilized on N-doped graphene nanoplatelets. Catalytic performances of the hybrid systems are tuned by chemical modification of graphene nanoplatelets via steric and electronic interactions between a metal center and graphene nanoplatelets.

    10. Water-Soluble Fluorescent Probes Based on Dendronized Polyfluorenes for Cell Imaging (pages 539–547)

      Libin Bai, Wei Li, Jingtian Chen, Fuli Bo, Baoxiang Gao, Hongmei Liu, Jingjing Li, Yonggang Wu and Xinwu Ba

      Version of Record online: 31 JAN 2013 | DOI: 10.1002/marc.201200722

      Thumbnail image of graphical abstract

      New water-soluble dendronized fluorescent polyfluorenes are designed. These polyfluorenes show two-color emission, good cytocompatibility, and differential cellular uptake. P1 shows limited cellular uptake and low brightness in cells. By contrast, P3 is efficiently internalized by cells and accumulated in the cytoplasm. A strong fluorescence from whole cells is also observed.

    11. Star-Shaped Polymer Consisting of a Porphyrin Core and Poly(L-lysine) Dendron Arms: Synthesis, Drug Delivery, and In Vitro Chemo/Photodynamic Therapy (pages 548–552)

      Dong Ma, Zong-Hua Liu, Qian-Qian Zheng, Xiao-Yan Zhou, Yi Zhang, Yun-Feng Shi, Jian-Tao Lin and Wei Xue

      Version of Record online: 6 FEB 2013 | DOI: 10.1002/marc.201200742

      Thumbnail image of graphical abstract

      A star-shaped polymer consisting of a porphyrin core and poly(L-lysine) dendron arms is synthesized and used for doxorubicin delivery. As shown, the drug-loaded complex is uptaken easily by CNE2 cells. In vitro toxicity assay confirms that the complexes shows a higher cytotoxicity under the light condition than polymer or doxorubicin alone, suggesting a potential application in combined photodynamic therapy and chemotherapy.
