      Front Cover: Cyclodextrin (CD)-based host-guest chemistry relies on specific, yet reversible non-covalent interactions between CD and a guest. Using this interaction, CD host-guest chemistry has been applied towards the fabrication of advanced functional assemblies and hydrogel materials. This review outlines new found applications using these materials which have renewed interest across a wide range of fields. Further details can be found in the article by S. Tan, K. Ladewig, Q. Fu, A. Blencowe* and G. Qiao* on page 1166.

    1. Optical Behaviors of Flexible Photonic Films via the Developed Multiple UV-Exposed Fabrications (pages 1185–1190)

      Chih-Chieh Chien and Jui-Hsiang Liu

      Article first published online: 9 APR 2014 | DOI: 10.1002/marc.201400009

      Thumbnail image of graphical abstract

      A highly ordered photonic polymer matrices is developed by imprinting helical structures from an induced chiral nematic mesophase through multiple photocrosslinking processes using flexible polyethylene terephthalate films as substrates. Tuning of colors of the imprinted cell is achieved by stretching the flexible cell in different lengths.

    2. The Guanidinium Group as a Key Part of Water-Soluble Polymer Carriers for siRNA Complexation and Protection against Degradation (pages 1191–1197)

      Ilja Tabujew, Christoph Freidel, Bettina Krieg, Mark Helm, Kaloian Koynov, Klaus Müllen and Kalina Peneva

      Article first published online: 4 APR 2014 | DOI: 10.1002/marc.201400120

      Novel guanidinium group containing block copolymer with precise architecture and low polydispersity displays excellent binding to siRNA. The polymer forms stable water-soluble nanosized complexes as determined by fluorescence correlation spectroscopy. The siRNA polymer complexes display excellent stability against RNA degradation and efficient release of the cargo in vitro.

    3. Surface Coordination Polymerization of Ethylene by Hydrozirconation-Immobilized Metallocene (pages 1198–1203)

      Jun Zheng, Yanhui Wang, Lin Ye, Yichao Lin, Tao Tang and Jidong Zhang

      Article first published online: 8 APR 2014 | DOI: 10.1002/marc.201400099

      Thumbnail image of graphical abstract

      Hydrozirconation is employed as a new approach for metallocene immobilization with Zr–C σ-bond, which is found in the place for surface-initiated coordination polymerization of ethylene to form substrates covalently linked metallocene-polyethylene. This strategy can be utilized to fabricate polyolefin hybrids materials in a very promising way.

    4. Rapid Hybridization of Chitosan-Gold-Antibodies via Metal-free Click in Water-based Systems: A Model Approach for Naked-eye Detectable Antigen Sensors (pages 1204–1210)

      Jatesuda Jirawutthiwongchai, Gerald Draeger and Suwabun Chirachanchai

      Article first published online: 14 APR 2014 | DOI: 10.1002/marc.201400092

      This work shows an approach to obtain chitosan hybridized with gold nanoparticles via metal-free click chemistry in which the reaction steps are performed in water at room temperature. The work also demonstrates how this provides a fast and practical approach for the detection of antigens with the naked eye.

    5. Fine-Tuning of Charge-Conversion Polymer Structure for Efficient Endosomal Escape of siRNA-Loaded Calcium Phosphate Hybrid Micelles (pages 1211–1215)

      Yoshinori Maeda, Frederico Pittella, Takahiro Nomoto, Hiroyasu Takemoto, Nobuhiro Nishiyama, Kanjiro Miyata and Kazunori Kataoka

      Article first published online: 8 APR 2014 | DOI: 10.1002/marc.201400049

      For rapid acid hydrolysis, a charge-conversion polymer (CCP) is developed by fine-tuning the structure of maleic acid amide moiety in the side chain. The calcium phosphate (CaP) hybrid micelle prepared with the CCP enables efficient endosomal escape of siRNA payloads, leading to enhanced gene silencing in cultured cancer cells.

    6. The First Suspension Polymerization for Preparing Optically Active Microparticles Purely Constructed from Chirally Helical Substituted Polyacetylenes (pages 1216–1223)

      Haiyang Zhang, Jiexuan Song and Jianping Deng

      Article first published online: 8 APR 2014 | DOI: 10.1002/marc.201400067

      Thumbnail image of graphical abstract

      Suspension polymerization is utilized for the first time to prepare substituted polyacetylene-based microparticles. Two substituted acetylene monomers, one chiral and the other achiral, undergo suspension polymerization in aqueous media, forming regular microparticles in high yield. The polymer chains constructing the microparticles adopt helical conformations. The microparticles formed from chiral monomer demonstrate CD effects.

      Thumbnail image of graphical abstract

      Polymer brushes are prepared via self-initiated photografting and photopolymerization of polymerizable vinyl monomers on the planar titanium dioxide surfaces, providing a facile and universal method for tailoring the surface functionality of TiO2.
