      Front Cover: The image shows the self-assembly of a highly asymmetric poly(butadiene-b-ethylene oxide) block copolymer in n-heptane into spheres and rod- and needle-like micelles. The fabrication of these crystalline morphologies can be tailored in solution through a thermally controlled crystallization of the PEO core and by adjusting the solvent quality for the PB corona chains. Further details can be found in the article by A. M. Mihut, M. Drechsler, M. Möller, and M. Ballauff*on page 449.

    1. Molecular Aspects of Radical Polymerizations—The Propagation Frequency (pages 419–442)

      Klaus Tauer and Hugo F. Hernandez

      Article first published online: 11 DEC 2009 | DOI: 10.1002/marc.200900609

      Thumbnail image of graphical abstract

      Monomer consumption as a result of chain propagation is the central reaction in radical polymerization. A comprehensive discussion of radical propagation kinetics is presented: its historical development, its experimental determination, the effect of local monomer composition at a molecular scale and its consequences for heterogeneous polymerization systems, and recent progress in the microscopic simulation of this process.

    1. Controlling the Optical Properties of Hyperbranched Conjugated Polyazomethines through Terminal-Backbone Interactions (pages 443–448)

      Liang Song, Chunlai Tu, Yunfeng Shi, Feng Qiu, Lin He, Yi Jiang, Qi Zhu, Bangshang Zhu, Deyue Yan and Xinyuan Zhu

      Article first published online: 8 DEC 2009 | DOI: 10.1002/marc.200900747

      Thumbnail image of graphical abstract

      A simple approach to tune the optical properties of hyperbranched conjugated polymers by only adjusting the terminal-backbone interactions is reported. The optical properties of the resultant hyperbranched conjugated polyazomethines could be tuned by altering the interactions between the amino terminal groups and the imine bonds in the backbone by changing the monomer feed ratio, protonation, coordination with SnCl2, or by complexation with β-cyclodextrin.

      Text for the Table of Content: A morphological study of the micellization of an asymmetric semicrystalline block copolymer, poly(butadiene)-b-poly(ethylene oxide), in the selective solvent n-heptane was investigate. A straightforward method to access different crystalline morphologies as spheres, rod-like or needle-like micelles is provided.

      Towards smart nanosensors, post-modification of gold nanoparticles by a dextran-based dual-sensitive polymer has been carried out. This smart material shows impressive stability under various conditions and pH-dependent optical response and aggregation behaviors upon heating.

    4. Design of Organoiron Macromolecules Based on Upper Rim Functionalized Calix[4]arenes (pages 459–466)

      Alaa S. Abd-El-Aziz, Patrick O. Shipman and Paul R. Shipley

      Dendritic and polymeric organometallic complexes were prepared using metallocalix[4]arenes. The dendritic species incorporated azo dyes in their structure and were shown to reversibly change colour in the presence of HCl(g), indicating their potential use as solid-state acid sensors. The prepared polymers showed thermal stability up to 230 °C when the cationic cyclopentadienyliron moiety decomposed. The backbone of the polymers was stable up to at least 500 °C.

    5. Electron Beam-Based Functionalization of Poly(ethersulfone) Membranes (pages 467–472)

      Agnes Schulze, Barbara Marquardt, Sven Kaczmarek, Rolf Schubert, Andrea Prager and Michael R. Buchmeiser

      Article first published online: 5 JAN 2010 | DOI: 10.1002/marc.200900666

      Thumbnail image of graphical abstract

      A new electron beam-based approach for the direct hydrophilization of PES membranes in a one-step procedure is presented. Aqueous solutions of functional molecules were immobilized on the membrane surface by electron beam treatment. The resulting membranes showed significantly increased hydrophilicity accompanied by decreased protein adsorption.

      The ability of a bis(germyl)ketone Ph3GeCOGePh3 to act as a photoinitiator of free radical polymerization under visible light is investigated. The results suggest that this compound could be the starting point of a new high-performance class of photoinitiators.

      Polymeric core–shell microstructures have been constructed by a new method, namely sequential precipitation. High-quality PVDF-PC-LiClO4 films with spherical core–shell microstructures, composed of conducting cores and insulating shells, have been generated by self-assembly and phase separation. Resulting from the percolation effect, the composite material presents a dielectric constant as high as 104–107.

      Irem Erel, Zhichen Zhu, Svetlana Sukhishvili, Elena Patyukova, Igor Potemkin and Elena Kramarenko

      Article first published online: 13 JAN 2010 | DOI: 10.1002/marc.200900659

      A combined theoretical and experimental study of self-assembly of a diblock copolymer with hydrophilic nonionic- and ionizable hydrophobic blocks has been performed. We find two novel types of micelle with hydrophobic ion-containing core blocks exhibiting either PE- or ionomer-like behavior, depending on solution pH and counterion type. Such micelles with stimulus responsive cores represent promising nanocarriers for controlled delivery applications.
