19_17/2009Aligned Nanofibers: Epitaxial Growth of Highly Oriented Fibers of Semiconducting Polymers with a Shish-Kebab-Like Superstructure (Adv. Funct. Mater. 17/2009)

Highly oriented fibers of regioregular poly(3-alkylthiophene)s with a “shish-kebab” morphology are prepared by epitaxy on long needles of 1,3,5-trichlorobenzene grown in liquid pyridine, as described on page 2759 by Brinkmann et al. The superstructure of the fibers consists of a highly oriented thread-like core several hundreds of micrometers long, the “shish”, onto which lateral crystalline nanofibrils made of folded polymer chains, the “kebabs”, are connected in a periodic way.
