Abstract

When deposited on metal surfaces, C60 creates nanoholes. Grazing incidence x-ray diffraction reveals a c (4×4) reconstruction induced by C60 on Pt (110) - (1×2). While the initial (1×2) missing row is partially deconstructed, under each fullerene we find double atomic vacancy involving two Pt layers. The resulting interface is deeply modified with a 75% Pt occupancy and regularly distributed double vacancy. The orientation of the molecule is compatible with local surface cm symmetry with a pentagonal ring almost parallel to the surface while hexagonal rings are almost parallel to the (111) facets of the nanohole. The short nearest-neighbor C60 distances increase the van der Waals repulsion forces that are minimized by a charge transfer between molecule and substrate involving a large number of C-Pt bonds and a reduction of 6% of the apparent diameter of the C60 molecule. © 2010 The American Physical Society.
