英文摘要	The growth, structure of Pt(111) supported double-layer FeO and the adsorption of titanyl phthalocyanine (TiOPc) molecules with tunable site and orientation were presented. According to the atomic-resolution STM image, the structure was rationalized as (8 root 3 x 8 root 3) R30 degrees/Pt(111) nanostructure constructed by Fe species coordinated with different number of oxygen on top of nonrotated (8 x 8) FeO/Pt(111) structure. Due to the modulation of the stacking of Fe atoms in the second layer relative to the O atoms in the second layer and the underlying layer, the interface and total dipole moment periodically vary within (8 root 3 x 8 root 3) R30 degrees/Pt(111) structure. The resulted periodically distributed dipole-dipole interaction benefits the growth of TiOPc molecules with area-selective sites and molecular orientations. Thus, this study provides a reliable method to govern the adsorption process of the polar molecules for potential applications in future functional molecular devices. (C) 2014 AIP Publishing LLC.
