摘要：

Large-area well-ordered monolayer of rubrene has been fabricated on Au(111) surface by gradually annealing a multilayer of rubrene in vacuum. Scanning tunneling microscopy clearly demonstrates that the rubrene monolayer experiences a disorder-order transition with increase of the annealing temperature and the molecules form dimer rows with opposite directions for two neighbored rows. The pi-pi and pi-H interactions between the molecules induced by conformation of the molecules in monolayer account for the main driving forces to form this kind of ordered layer.
