    The synthesis of a new amphiphilic brush copolymer through a “grafting onto” method via carbon dioxide chemistry is described. The polymer shows high grafting densities of 97%–98% and a hydroxyurethane structure as the junction site between the poly(glycidyl methacrylate) backbone and side polyethylene glycol chain

  2. Single Molecule Studies of a Ladder Type Conjugated Polymer: Vibronic Spectra, Line Widths, and Energy Transfer

    Martin F. Zickler, Florian A. Feist, Josemon Jacob, Klaus Müllen and Thomas Basché

    Article first published online: 30 MAR 2015 | DOI: 10.1002/marc.201400739

    Single molecules studies of a ladder type conjugated polymer are presented. The combination of fluorescence emission and excitation spectroscopy at cryogenic temperatures reveals detailed spectroscopic characteristics of individual chains. As a particular advantage, excitation spectroscopy gives access to nonemitting chromophores which would be missed by emission spectroscopy and whose line widths contain information about energy transfer times.

  3. A Straightforward Method for Preparing Well-Defined Responsive Diselenide-Containing Polymers Based on ATRP

    Caiwei Fan, Chunlai Ding, Xiangqiang Pan, Zhengbiao Zhang, Jian Zhu and Xiulin Zhu

    Article first published online: 30 MAR 2015 | DOI: 10.1002/marc.201500034

    The atom transfer radical polymerization-based protocol presented in this work allows for a facile fabrication of diselenide-containing polymers of various composition, predictable molecular weight, and programmable polymeric architectures. The redox sensitive disel­­enide structure makes these polymers potential building blocks for applications in various fields.

  4. D-π-A Conjugated Molecules for Optoelectronic Applications

    Tae-Dong Kim and Kwang-Sup Lee

    Article first published online: 27 MAR 2015 | DOI: 10.1002/marc.201400749

    This article provides a brief review of the current status of research related to D-π-A dipolar chromophores together with a description of their syntheses and several promising applications in related fields. Structure/property relationships are discussed in order to exploit the potentials by tuning the π-electron density, polarizability, and HOMO–LUMO band gap of the chromophores.

  5. Synthesis and Conformation of 3,6-Connected Cyclohexadiene Chains

    Florian E. Golling, Amelie H. R. Koch, George Fytas and Klaus Müllen

    Article first published online: 27 MAR 2015 | DOI: 10.1002/marc.201400712

    The synthesis of novel 3,6-dimethoxy­cyclohexadiene oligomers is reported. Their structure is investigated by density functional theory calculations and dynamic light scattering measurements, confirming the formation of linear and rigid chains, which allow for the synthesis of poly(para-phenylene) derivatives.
