摘    要:Self-assembled monolayers of novel C60 derivative, N-3-γ-pyridyl Aza[60]fulleroid (C60Py), on Au(111) were studied by a scanning tunneling microscope under ultrahigh vacuum (UHV). C60Py molecules were assembled on Au (111) via pyridyl nitrogen-Au interaction. The sole assembly of C60PY molecules on Au (III) only exhibited randoml aggregation of C60PY even the films were annealed at 50 and 105℃ .By co-assembling with benzyl mercaptan (BM), the C60PyBM films showed highly dense aggregation, but C60Py assemblies still had disordered structure. After the co-assembled C60Py-BM films were annealed at 50℃, BM molecules were partially desorbed, but the assembly of C60Py remained without obvious change. After the co-assembled C60Py-BM films were further annealed at 105℃, the C6oPy monolayers with ordered structure were obtained, while the BM molecules were nearly thoroughly desorbed from the surface. Here, the BM molecules play a key role as a surfactant in the formation of the ordered C6oPy monolayer.

Abstract:Self-assembled monolayers of novel C60 derivative, N-3-γ-pyridyl Aza[60]fulleroid (C60Py), on Au(111) were studied by a scanning tunneling microscope under ultrahigh vacuum (UHV). C60Py molecules were assembled on Au (111) via pyridyl nitrogen-Au interaction. The sole assembly of C60Py molecules on Au (111) only exhibited randoml aggre-gation of C60Py even the films were annealed at 50 and 105℃. By co-assembling with benzyl mercaptan (BM), the C60Py- BM films showed highly dense aggregation, but C60Py as-semblies still had disordered structure. After the co-assembled C60Py-BM films were annealed at 50℃, BM molecules were partially desorbed, but the assembly of C60Py remained without obvious change. After the co-assembled C60Py-BM films were further annealed at 105℃, the C60Py monolayers with ordered structure were obtained, while the BM molecules were nearly thoroughly desorbed from the surface. Here, the BM molecules play a key role as a surfac-tant in the formation of the ordered C60Py monolayer.
Keywords:N-3-γ-pyridyl Aza[60]fulleroid (C60Py)  scanning tunneling microscopy  self-assembled monolayers (SAMs)  surfactant  co-assembly.
