摘　　要：We described the formation of self-organized two-dimensional (2D) assemblies of N-(2,3,5,6-tetrafluoro- 4-iodophenyl)hexadecylamine and 1-dodecyl-imidazole at the liquid/HOPG interface. The two-dimen- sional assemblies showed a fishbone-like pattern structure as revealed by high-resolution scanning tunneling microscopy. Although different interactions can drive the formation of 2D assemblies, as far as we know, this is the first report on halogen bond-driven 2D assemblies.We described the formation of self-organized two-dimensional （2D） assemblies of N-（2,3,5,6-tetrafluoro 4-iodophenyl）hexadecylamine and 1-dodecyl-imidazole at the liquid/HOPG interface.
