摘要：

We have investigated steady-state photoabsorption spectra of a soluble polyacetylene prepared by a recently devised technique. Measurements were carried out both on solutions and trans-isomerized films. We have found that photoexcitation of the polyacetylene transforms only into neutral solitons in the temperature range 85-300 K. Simultaneously, photoabsorption spectra of films show thermal bands due to temperature modulation of the absorption edge.
