| 摘 要： | Large-area self-assembly of rubrene has been fabricated on Au（111） surface and studied by scanning tunnelling microscopy. The rubrene monolayer on A u（111） surface is characterized by well-ordered row-like structures similar to the a-b plane of rubrene single crystal. However, the directions of the neighboured molecular rows are opposite to each other. In a two-layer film of rubrene on Au（111） surface, the arrangements of the top molecular rows are determined by the underneath rows, suggesting an orthorhombic crystal structure with a = 1.26 nm, b = 4.36 nm, c = 0.17nm for multilayer ofrubrene on Au（111）.
