Abstract

We report on polysilane, a synthetically accessible μ-conjugated silicon-catenated polymer with such semiconducting properties as photoconductivity, high hole drift mobility, and electroluminescence, as a candidate for molecular wire. We apply the “end-graft” technique, which we developed for fixing individual polymer chains on a substrate surface, to a semiflexible polysilane. The end-grafted semiflexible polysilane extended more than 500 nm across the Si(111) surface, and was clearly observed by means of atomic force microscopy (AFM).
