Abstract

A storage material for obtaining H-silanes which is present in the form of a hydrogenated polysilane (HPS), as a pure compound or as a mixture of compounds having on average at least six direct Si—Si bonds, the substituenis of which predominantly consist of hydrogen and in the composition of which the atomic ratio of sabstitueot to silicon is at least 1:1.
