The synthesis of 2,5-dipropenylthiophene monomer possessing exclusively cis-double bond configurations through reduction of dipropynylthiophene precursor is reported. Lindlar's catalyst was found to be completely ineffective, while a dissolving metal method involving activated zinc proved successful in alkyne reduction to cis-alkenes with high yields and excellent selectivity. Acyclic diene metathesis polymerization of the monomer afforded poly(2,5-thienylene vinylene) polymer of high molecular weight.

Article first published online: 7 DEC 2013 | DOI: 10.1002/pola.27041
A series of new crosslinkable conjugated polymers, derivatives of region-regular poly(3-hexylthiophene), are synthesized and investigated in organic photovoltaic devices. The individual effect of the conditions employed in the crosslinking is investigated, and an overall beneficial effect upon crosslinking on the device stability is shown.
- Synthesis and electrochromic properties of triphenylamine containing copolymers: Effect of π-bridge on electrochemical properties

Article first published online: 6 DEC 2013 | DOI: 10.1002/pola.27030
Benzotriazole and triphenylamine bearing random copolymers are synthesized. Electrochemical and spectroelectrochemical properties of the P1, P2, and P3 are performed, and the results are highlighted. Promising properties of these materials make them good candidates for electrochromic devices and organic solar cells.
- Effect of permodified β-cyclodextrin on the photophysical properties of poly[2,7-(9,9-dioctylfluorene)-alt-(5,5′-bithiophene)] main chain polyrotaxanes

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

Article first published online: 3 DEC 2013 | DOI: 10.1002/pola.27036
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.
