Control of Electronic, Magnetic and Optical Properties of Doped Polyacetylene Conductors

摘要

The electronic properties of the novel class of conducting polymers have been investigated using a variety of techniques. Studies during the period of this grant focused on polyacetylene (a conjugated polymer with a degenerate ground state) and polythiophene (an analogous polymer in which the ground state degeneracy has been lifted). Photoinduced absorption and photoinduced ESR studies were carried out on these polymers. In addition an extensive study of the effects of radiation damage on (CH)x and (CD)x was completed. The construction of a versatile x-ray scattering apparatus was completed and the instrument was used to study the charge density wave state in a quasi-one-dimensional conductor.
