Surface Review and Letters
The electrochemical behaviour of a variety of para-substituted n-phenylpyrrole monomers and their corresponding polymers was analyzed. The electron-attractive or electron-repulsive nature of each para group substituent was perceived in the pyrrole unit through the phenyl ring and manifested in their EPa values. Good linear correlations with Hammett σ+ constants were obtained for both the monomer Epavalues and the electroactive polymer E0 values. © 1984, The Electrochemical Society, Inc. All rights reserved.
