Soluble Polysilane Derivatives: Chemistry and Spectroscopy,
Abstract
Polysilanes represent an interesting class of radiation sensitive polymers for which new applications have been discovered. Even though the polymer backbone is composed only of silicon silicon single bonds, all high molecular weight polysilanes absorb strongly in the UV. The position of this absorption depends not only on the nature of the substituents, but also on the conformation of the backbone. In this regard, materials where the polymer backbone is locked into a planar zigzag conformation absorb at much longer wavelengths than comparable materials where the backbone is either disordered or nonplaner (e.g., helical). A planar zigzag backbone is often observed for symmetrically substituted derivatives in the solid state when there are also significant intermolecular interactions such as side chain crystallization. These materials are strongly thermochromic. Keywords: Soluble polysilanes, Structure, Thermochromism, Polymer morphology.
