CONFORMATIONALLY LOCKED ORGANOSILANE HIGH POLYMERS.

One of the most intriguing properties of polysilane derivatives is their electronic absorption spectra. It has been found that most simple alkyl substituted silane high polymers absorb around 305-320 nm. This paper presents the observation that this limiting value apparently applies only to polysilane derivatives in solution or in the amorphous solid state. A number of symmetrically disubstituted derivatives were prepared by an anionic technique which is described.
