Individual adsorption and two-dimensional assembling of 5,10,15,20-tetrakis(4-bromophenyl)-porphyrin-Co (TBrPP-Co) molecules on a Si(111)-root 3 x root 3 Ag reconstructed surface have been studied using low-temperature scanning tunnelling microscopy (STM). All the isolated molecules are observed in a planar shape with slight distortion. The isolated molecules can be controllably rotated with an STM tip to the orientation along the [11 (2) over bar] direction) of the substrate. With an increased coverage (0.07 ML) and appropriate annealing, the molecules assemble to form three types of ordered phase. The long-range ordered structures, however, disappear at higher coverage (0.75 ML).
