Graphical Abstract
Potential causes: The combination of potential-pulse perturbation and STM has shown that the interfacial oxidation of an adsorbed 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphine (TPyP) monolayer at the Au(111)/0.1 M H2SO4 interface is spacially heterogeneous (see STM image; dark spots: oxidized TPyP, light spots: nonoxidized TPyP). The distribution of the oxidized TPyP molecules on the surface depends on the oxidation potential and varies with time.
