Fig. 2. Curve A Eleotropolymerization of ImH H2(o-NH2)TPP in 0.1M Et NClO /CH CN by sweeping potential at 200mV/s on Pt electrode. Numbers represent scan number. Curve B Cyclic voltammogram of an electropolymerized film of poly-[H2(o-NH2)TPP] on a Pt electrode, in 0.1M Et NClO /CH CN at 200 mV/s. Integration of the charge under the wave shows that coverage is 3.5X10 9 mol/cm of the porphyrin sites. Curve C Rotated disk electrode voltammetry of the Os(lII,Il) reaction for 0.2 mM...

Although cyclic voltammetry could fruitfully be applied to the kinetic analysis of these catalytic systems, it has mostly been investigated by means of rotating disk electrode voltammetry (Section 1.3.2). The simplest case is that of an irreversible catalytic reaction at a monolayer coating. The next section is devoted to the analysis of these systems by the two techniques.

The redox properties of the sandwich complexes have been studied by cyclic-, rotating disk electrode voltammetry and electrolysis, in different solvents (CH202,DMF,DMSO,benzonitrile). The reference for the potentiel scale is the ferri/ferrocenium couple.

Rotating disk electrode voltammetry was used to determine the apparent diffusion coefficients (Dapp) of the ferrocene derivatives. The >app values depend on the added concentration of host and reflect the position of the host-guest association equilibrium because the inclusion complexes diffuse substantially more slowly than the corresponding free guests. We utilized this concentration dependence to determine the equilibrium constants for the formation of each of the host-guest complexes surveyed here. The details of this method have been already published by us [14].
