• (111). Manipulation of the electronic structure of H2TPP(OH)4 on Au(111) [45]: Molecules with two possible states, e.g., of conductivity, can be used as single-molecule switches. This functionality could be applied in nano-scaled molecular-based memory devices or logic gates [64], However, one must be
