Tuning the Electronic Communication between Redox Centers Bound to Insulating Surfaces

Controlling communication: The electronic communication between ferrocenyl centers bound to insulating silicon surfaces can be efficiently controlled; scanning electrochemical microscopy (SECM) shows that both the surface coverage of the electroactive units and the nature of the redox mediator allow for this control. The lateral charge propagation can be precisely tuned from an extremely slow to a very fast process.
