Abstract
Highly oriented poly(dimethylsilylene) films, which were prepared by friction-transfer technique, have an ability of orienting soluble polysilanes. Solution-cast films of polysilanes on the friction-transferred film were oriented. The oriented films were characterized by polarized ultraviolet absorption spectroscopy. Several soluble polysilanes were examined and then poly(di-n-hexylsilylene) and poly(methyl-n-propylsilylene) had higher orientation. Their main chains were arranged along the main chains of the poly(dimethylsilylene).
