Method for producing polysilanes

摘要

The present invention provides a method for producing polysilane characterized in that starting halosilane is subjected to electrochemical reaction using Mg or Mg alloy as anode, lithium salt as supporting electrolyte and aprotic solvent as solvent, thereby producing polysilane. The present invention affords polysilane in a high yield, whose molecular weight is uniform and high enough to be cast into an excellent thin film, with an ease of handling, safety and a low cost ensured.
