The film by tetraphenyIporphyrin((TPP)H₂) vapor deposition on iron was investigated by means of XPS, SEM and visible spectroscopy. N(1s) binding energy characteristic of (TPP)H₂ was gained directly from the deposited samples. N(1s) binding energy of the surface was greatly changed after the deposited sample was washed with solvent. It is indicated that the deposited film is composed of an outer-layer of physically adsorbed (TPP)H₂, and an inner-layer of chemically modified (TPP)H₂.
