Selected Aspects of Organoelectrochemistry

11.6.4. Conclusion

Many expertly designed new electrode surfaces have been created (R. Murray, 1992–1998) and made active by mixing the polymer with some kind of redox system, which in turn brings about the oxidation or reduction of the reactant. Several factors are intertwined here: the permeation of the reactant into the film which reaches an optimal thickness, electron-transfer steps, and steps involving surface reaction.

There are undoubtedly systems where the net result of the use of macrocycles is advantageous (e.g., use of the crown ethers by Wass in 1989 to photo reduce CO 2 ); it is necessary to be sure that the increase in rate is more than an effect of the extra area introduced (which is somewhat similar to that arising from the use of a porous electrode containing a metal catalyst) before one concludes that there is a catalytic effect per real square centimeter due to the new structure.
