Abstract
The formation of a molecular assembly through the chain reaction of some simple vinyl substituted acenes with the dangling bond site of H-terminated Si(100)-(2 × 1) surface has been studied under ultrahigh vacuum conditions at room temperature. The molecular assemblies formed on the surface were checked using an in situ scanning tunneling microscope (STM). While styrene and 2-vinylnaphthalene undergo a dangling bond initiated chain reaction forming a perfectly ordered one-dimensional (1D) assembly as expected, 9-vinylanthracene exhibits unique behavior in forming the molecular assemblies studied to date. Both the perfectly ordered 1D and irregularly shaped disordered assemblies are formed by the 9-vinylanthracene molecules on the surface, which allows us to directly compare the interaction between molecules in two different assemblies. Biased dependent changes of the relative contrast of ordered and disordered assemblies formed by 9-vinylanthracene indicates a significant π–π interaction between the molec...
