Ferrocene oxidation

These results show that significant anodic shifts in the ferrocene oxidation wave result if cations are added to the conjugated receptor systems where the 7r-electron system links the heteroatoms of the ionophore to the redox centre.

In conclusion, with these types of ligand systems anodic perturbations of the ferrocene oxidation wave are observed if a conjugated 77-electron system (—C=C—, —CH=N—) links the heteroatoms of the crown ionophore to the redox center, and the polarizing power of the guest metal cation is of great importance in determining the magnitude... 

This reaction is easier by 0.4 V than ferrocene oxidation. It might be assumed that analogously with other metallocenes, the electron charges in... 

The potential value for ferrocene oxidation shows no or only minor dependence on dendrimer generation. 

Compound 2 is a third-generation dendrimer based on a poly(arylether) structure and contains 24 equivalent ferrocenyl units even in this case the potential required for ferrocene oxidation was essentially the same observed in lower-generation analogues [55].
