Abstract :
Thin, spin-cast layers of poly(octylthiophene) were shown to be partially crystalline. For thin samples, the crystalline part is orientated with both the alkyl side chains and the polymer main chains parallel to the substrate surface. The orientation effect disappears irreversibly upon heat treatment of the polymer layer. For poly(dioctylbithiophene), no orientation effect was found.
