Solid-state films of chiral polysilanes undergo an optical inversion (see Figure) above a helix–helix transition temperature, determined by the polymer molecular weight and by the thermal processing. These films could be used for re-writable or write-once, read-many data storage, depending on the molecular weight and the transition temperature.
