Research Abstract

Heptazine derivatives are candicates as building blocks for functional nano-architectures, because of the monomers of graphitic carbon nitrides as metal-free photocatalysts. In this research, we found the ordered self-assembled structures of melem monocation at the aqueous solution–Au(111) interface. In addition, the adsorbed structures of cyamerulate anions were formed at the aqueous solution–Au(111) interface, and EC-STM revealed that the structures were stable under the electrochemical potential control.
