Encapsulations of bithiophene units from poly[2,7-(9,9-dioctylfluorene)-alt-(5,5′ -bithiophene)] copolymer chains into persilylated or permethylated β-cyclodextrin cavities, leads to distinct improvements in the solubility, transparency and film forming ability. The photoluminescence exhibits a well-defined vibronic structure with a predominance of the 0-0 transition and a fluorescence lifetime which follows a mono-exponential decay. The increased height of the rod-like structures may indicate a higher tendency of the polyrotaxane chains to organize into fibers in the solid states.
- Thiol-responsive micelles based on nonionic gemini surfactants with a cystine disulfide spacer

Novel non-ionic gemini surfactants with a cystine disulfide spacer were synthesized for the preparation of thiol-responsive micelles. The release of a hydrophobic drug from the gemini surfactant micelles was accelerated with increasing the concentration of the reducing agent, glutathione (GSH); however, the release profiles in the presence of reduced GSH (as well as glutathione disulfide (GSSG)) were similar to those of the control experiment.
- Linear poly(amide triazole)s derived from d-glucose

Article first published online: 3 DEC 2013 | DOI: 10.1002/pola.27038
Degradable linear polymers, with different degree of hydrophilicity are obtained. The repeating unit contains a free alcohol function, while the others secondary alcohols are protected. The polymerization reaction is followed through DSC analysis and 1H NMR spectroscopy.
- Synthesis and characterization of polyamine-based cyclophosphazene hybrid microspheres
Jens Köhler, Sebastian Kühl, Helmut Keul, Martin Möller and Andrij Pich
Article first published online: 1 DEC 2013 | DOI: 10.1002/pola.27028
Based on HCCP and bPEI crosslinked cyclomatrix polyphosphazene poly(HCCP-co-bPEI) microspheres are prepared by precipitation polymerization in acetonitrile. By adjusting the reagent ratio in the feed an effective control of chlorine substitution, chemical composition, and thermal properties, as well as particle size and morphology is achieved. The presence of free amine groups on the surface offers the possibility of further functionalization or for the use as flame-retardant finish for fibers and fabrics.
- Transparent room temperature cured elastomers based on bisphenol a
Mollie B. Schear and Matthew Laskoski
Article first published online: 1 DEC 2013 | DOI: 10.1002/pola.27027
The synthesis and room temperature polymerization of a bisphenol A based divinyl resin is demonstrated. The cured resin exhibited good thermo-oxidative stability and mechanical properties.
