Abstract

The emission of secondary radiation from polyacetylene is reported for neutral and electrochemically doped samples. For neutral material the interruption of the π-electron system without interruption of the chains was found responsible for the dispersion effect of the Raman lines. In situ Raman spectroscopy in an electrochemical cell revealed that short conjugated segments dope first and undope last which is explained by an upshift of the chemical potential for the short segments. In addition a luminescence directly correlated to the doping and undoping process was observed. This effect is discussed in terms of olaron states.
