摘要：

Electroanalytical experiments show that overoxidized polypyrrole, especially the corresponding beta,beta'-substituted polymers, poly(3-methoxy-4-methylpyrrole) and poly(3,4-dimethylpyrTole), shows a high affinity for dissolved dioxygen. This interaction occurs after deprotonation of the overoxidized polymer. The overoxidation potentials necessary for this interaction are low (about +0.2 to 0.5 V versus SCE), i.e., lower than the oxidation potentials which lead to the addition of nucleophiles from the solution.
