摘要：
The transient redox behavior of polypyrrole in acetonitrile containing 10 ± 1 ppm water has been studied in the presence of the spherical anions ClO4-, BF4- and PF6- by a spectroelectrochemical method. The rate of absorbance changes as well as the transferred charge values registered after different potential steps have been correlated to the radii and association tendencies of the anions participating in the redox process. It is concluded that 'net' effect of the dopant can be observed only when hydration of the anions is excluded as far as possible.
