- Synthesis of an Amphiphilic Brush Copolymer by a Highly Efficient “Grafting onto” Approach via CO2 Chemistry
Ying-Ying Zhang, Yang Li, Xian-Jing Zhou, Xing-Hong Zhang, Bin-Yang Du and Zhi-Qiang Fan
Article first published online: 30 MAR 2015 | DOI: 10.1002/marc.201400718
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
- 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

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.
- 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.
- 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.
- 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.
