Abstract

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.
