Optical and Electronic Properties of a Highly Disordered Form of Polyacetylene — Distinguishing Between Localized Defects and Conformational Disorder
We report on the electronic and optical properties of highly disordered polyacetylene prepared by the Durham “Photoisomer” precursor route. This form of polyacetylene has a high degree of conformational disorder and there is a shift of all band-gap related optical features to higher energies. However, the photo-induced absorption feature seen between 1.35 and 1.5 eV in other forms of polyacetylene is not observed in this material.
