Silvered molecules: The controlled metalation of individual phthalocyanine (H2Pc) molecules to form AgPc was observed by low-temperature scanning tunneling microscopy (STM). Stepwise dehydrogenation was followed by Ag+ implantation; tautomerization and hydrogen atom hopping within the H2Pc inner ring were also induced by electron injection from the STM tip.
