Polysilanes are organosilicon compounds with the formula (R2Si)n. They are relatives of traditional organic polymers but their backbones are composed of silicon atoms. They exhibit distinctive optical and electrical properties. They are mainly used as precursors to silicon carbide.[1] The simplest polysilane would be (SiH2)n, which is mainly of theoretical, not practical interest.[2]
