摘要：

The molecular orientation and interface properties of Fe(II) hexadecafluoro-phthalocyanine (FePcF16 ) on Ag(111) are investigated by photoexcited electron spectroscopies: X-ray photoemission spectroscopy (XPS), X-ray absorption spectroscopy (XAS), and resonant photoemission (ResPES). The data are compared to those for FePcF(16 )on Au(111). The molecules are oriented predominantly flat, lying on both substrate surfaces; increased tilts are observed for FePcF16 on Au(111). On Ag(111), the electronic structure of FePcF16 is distinctly altered at the interface, involving both the macrocycle and the central metal atom. An interface state close to the Fermi energy exhibits a clear Fe character.
