Changing abruptly the potential between a scanning tunneling microscope tip and a graphite substrate induces "high-conductance" spots at the molecular level in a monolayer formed by a manganese chloride-porphyrin molecule. These events are attributed to the pulse-induced formation of μ-oxo-porphyrin dimers. The pulse voltage must pass a certain threshold for dimer formation, and pulse polarity determines the yield.
