Abstract

Novel trihydridosilyl-terminated polysilanes and methods for their synthesis, which are applicable to other polysilanes, are provided. The synthetic methods provide for facile preparation of products with minimal handling of pyrophoric intermediates and byproducts. The novel compounds contain at least three silicon-silicon bonds and at least one terminal silicon atom having three hydrogen substituents.
