Well‐defined pyrrole oligomers: Electrochemical and UV/vis studies

Abstract

The properties of oligo(pyrrole)s can give vital clues to the intrinsic properties and behavior of poly(pyrrole), which is important in the field of polyconjugated conducting polymers but difficult to obtain defect‐free. However, up to now little work has been done on oligo(pyrrole)s, perhaps because of their sensitivity to oxygen, which makes their handling and preparation difficult. The reported electrochemical analysis of well‐defined pyrrole oligomers has allowed both the determination of the limiting value for the potential of reversible charging of poly(pyrrole) and the production by electrochemical coupling of a virtually defect‐free poly(pyrrole).
