Generation and Characterization of Chain Defects in Polyacetylene

Abstract

Investigations of defects of carefully prepared trans-(CH)_x are presented. The dependence of conjugation length on the generation of various types of defects was observed by resonance Raman scattering. In the case of sample oxidation a quantitative comparison of these results combined with a determination of weight uptake leads to a distinction between oxygen interrupting chains and oxygen reacting at chain ends.
