摘要

Self-assembly of metal phthalocyanine (MPc) molecules on monolayer graphene (MG) epitaxially grown on Ru(0001) and Pt(111) is investigated by means of low-temperature scanning tunneling microscopy. At low coverage, dispersive single molecules, dispersive molecular chains, and small patches of Kagome lattice are observed for iron phthalocyanine (FePc), manganese phthalocyanine (MnPc), nickel phthalocyanine (NiPc), and phthalocyanine (H ₂Pc) on MG/Ru(0001). In contrast, although MG/Pt(111) exhibits various domains with different moiré patterns and corrugations, FePc molecules always form densely packed two-dimensional islands with a square lattice on MG/Pt(111) at submonolayer coverage. The different self-assembling behaviors of MPc molecules on MG/Ru(0001) and MG/Pt(111) originate from a subtle balance between molecule-molecule and molecule-substrate interactions tuned by central metal ions of the MPc molecules and the metal substrates.
