      Front Cover: The cover picture shows cyclodextrins (CDs) can discriminate subtle protein structural differences of human and bovine serum albumins (HSA and BSA, respectively). Two-dimensional nuclear Overhauser effect spectroscopy and circular dichroism spectroscopy demonstrate that α-CD and β-CD interact with the tyrosine and/or phenylalanine residues exposed on the surface of HSA but not with those of BSA, although HSA and BSA are homologous proteins. Further details can be found in the Communication by W. Oi, M. Isobe, A. Hashidzume, and A. Harada*on page 501.

      Back Cover: The cover picture shows PANI microtubes with hexagonal cross-section synthesized via a self-assembly process in presence of 8-hydroxyquinoline-5-sulfonic acid (HQS) as the dopant for the first time. Interestingly, the PANI/HQS reacted with metal ion (e.g. Zn2+) show the pH dependence of fluorescence. Further details can be found in the article by Z. Liu, Y. Zhu,* L. Wang, M. Ding, N. Wang, M. Wan, and L. Jiang*on page 512.

    1. ‘All-supramolecular’ Nanocapsules from Low-Molecular Weight Ureas Through Interfacial Addition Reaction in Miniemulsion (pages 491–496)

      Emilie Groison, Salim Adjili, Alice Ferrand, Frédéric Lortie, Daniel Portinha and Nathalie Sintes-Zydowicz

      Version of Record online: 21 JAN 2011 | DOI: 10.1002/marc.201000662

      ‘All-supramolecularnanocapsules based on bis-ureas are spontaneously formed by controlling the interfacial addition reaction in miniemulsion between diisocyanate and monoamine; nanocapsules with a diameter around 100nm were formed, and the wall-forming moieties of the nanocapsules are of low-molecular weights, strongly suggesting that hydrogen-bonded ureas are responsible for the cohesion of the nanocapsule membrane.

    2. A Dual Colorimetric and Fluorometric Sensor for Lead Ion Based on Conjugated Polydiacetylenes (pages 497–500)

      Simple methods for detecting lead have always been received because of the adverse health effects of lead exposure, particularly in children. In this report, we have developed a new PDA-based chemosensor system for the detection of Pb2+ in aqueous solution. Among the various metal ions, PDA-DPA-1 displayed a selective colorimetric change from blue to red, as well as fluorescence enhancement. Most importantly, the presence of Pb2+ can be easily monitored via naked-eye detection.

    3. Macromolecular Recognition: Discrimination between Human and Bovine Serum Albumins by Cyclodextrins (pages 501–505)

      NOESY data demonstrated that α-CD and β-CD can discriminate subtle differences between human and bovine serum albumins. NOESY is a useful technique to investigate very weak interaction of CDs.

    4. Synthesis and Photovoltaic Properties of Ester Group Functionalized Polythiophene Derivatives (pages 506–511)

      Xiaolian Hu, Minmin Shi, Jian Chen, Lijian Zuo, Lei Fu, Yujing Liu and Hongzheng Chen

      Version of Record online: 24 JAN 2011 | DOI: 10.1002/marc.201000711

      Two new ester group functionalized polythiophene derivatives, PCTDT and PCTBDT, were synthesized. The two polymers posses relatively low HOMO energy levels and photovoltaic devices based on them have presented both high VOC and JSC.

    5. Polyaniline Microtubes with a Hexagonal Cross-Section and pH-Sensitive Fluorescence Properties (pages 512–517)

      Zhaoyuan Liu, Ying Zhu, Liang Wang, Chunmei Ding, Nü Wang, Meixiang Wan and Lei Jiang

      Version of Record online: 27 DEC 2010 | DOI: 10.1002/marc.201000638

      A large-scale preparation of polyaniline (PANI) microtubes with a hexagonal cross-section is synthesized in presence of 8-hydroxyquinoline-5-sulfonic acid (HQS) as the dopant via a self-assembly process, for the first time. It is proposed that the aniline/HQS salts are served as a hard template for the formation of the hexagonal-cross-section microtubes. Moreover, the PANI/HQS reacts with metal ions (e. g. Zn2+), showing a pH dependence of the fluorescence.

    6. Ring Opening Metathesis Polymerization Derived Polymers as Photoresists: Making Use of Thiol-ene Chemistry (pages 518–522)

      Archim Wolfberger, Barbara Rupp, Wolfgang Kern, Thomas Griesser and Christian Slugovc

      Ring opening metathesis polymerization derived poly(norbornene) films and aggregates were crosslinked via photo chemically induced thiol-ene chemistry using a multifunctional thiol and the double bonds present in the polymer backbones. The presented method was illustrated by the description of a negative-toned photoresist formulation based on above mentioned ingredients.

    7. Association of a Cylindrical Polyelectrolyte Brush with Tetravalent Counterions (pages 523–527)

      Curls and assembled curls: Curled polyelectrolyte bottle brushes and assemblies consisting of curled brushes that are stable in aqueous solution can be obtained by electrostatic self-assembly of an anionic poly(styrene sulfonate) cylindrical brush and tetravalent organic cations.

    8. A Supramolecular Approach on Using Poly(fluorenylstyrene)-block-poly(2-vinylpyridine):PCBM Composite Thin Films for Non-Volatile Memory Device Applications (pages 528–533)

      Write-once-read-many times (WORM) memory devices were prepared from block copolymers composite thin films of PCBM:P(St-Fl)-b-P2VP using a supramolecular approach. The well-dispersed PCBM aggregation in P(St-Fl)-b-P2VP block copolymers matrix provide electric field induced charge transfer channels to switch the device from OFF state to ON state.

    9. A Facile Strategy for Constructing Boron-Rich Polymer Nanoparticles via a Boronic Acid-Related Reaction (pages 534–539)

      Luzhong Zhang, Ying Lin, Jingjing Wang, Wei Yao, Wei Wu and Xiqun Jiang

      Version of Record online: 27 JAN 2011 | DOI: 10.1002/marc.201000757

      A facile strategy for preparing dextran-poly(3-acrylamidophenylboronic acid) nanoparticles (Dextran-PAPBA NPs) is established through the polymerization of the 3-acrylamidophenylboronic acid (APBA) monomer in an aqueous medium in the presence of dextran that can bind APBA via the boronic acid-diol reaction.

    10. Highly Efficient Drug Delivery Nanosystem via L-Phenylalanine Triggering Based on Supramolecular Polymer Micelles (pages 540–545)

      Version of Record online: 24 JAN 2011 | DOI: 10.1002/marc.201000693

      In this report a highly efficient drug delivery nanosystem is developed via L-phenylalanine triggering based on supramolecular polymer micelles. Remarkably, upon triggering, the drug release rate increases by two orders of magnitude compared to that of the control, showing great promise for efficient controlled-release of potent hydrophobic photosensitizers in cancer treatment.

    11. A Lipase-Responsive Vehicle Using Amphipathic Polymer Synthesized with the Lipase as Catalyst (pages 546–550)

      Jun Ge, Diannan Lu, Cheng Yang and Zheng Liu

      Version of Record online: 21 JAN 2011 | DOI: 10.1002/marc.201000746

      Thumbnail image of graphical abstract

      Rapid release on command: A lipase-dissociable polymeric vehicle is formed, in which the modified dextran is synthesized using lipase as catalyst in DMSO. Rapid release of protein incorporated in the polymer vehicle in aqueous phase occurs on the command of adding lipase to hydrolyze the polymer.
