摘要：
The spatial arrangement of magnesium phthalocyanine (MgPc) molecules has been investigated on FeO films grown on Pt(111) with low-temperature STM. The polar oxide film forms a coincidence lattice with the Pt support and exhibits a surface dipole between the Fe delta+ and O delta- layers that varies across the coincidence unit cell. The MgPc molecules preferentially adsorb in regions with large dipole strength. The rotational orientation of the MgPc molecules, on the other hand, is determined by their interaction with the atomic Fe-O lattice.
