Golden logic : The integration of both cathodic and anodic electrochemical current rectifiers (ECR) on a gold electrode (see picture) results in a molecular‐level XOR logic gate with a high switch ratio between electrical output signals “1” and “0”. When the electrode is modified by the redox mediator ferrocene, successive XOR logic‐gate functions can be carried out without resetting the system.
