This thesis discusses the deposition, self-assembly, network formation, and molecule-substrate interaction of brominated molecules with four-, three- and two-fold symmetry on the Au(111), Au(110), Ag(111) and Cu(111) metal
surfaces. Characterisation was carried out using scanning tunneling microscopy(STM), x-ray photoelectron spectroscopy (XPS), low energy electron diffraction(LEED), and synchrotron radiation based photoelectron spectroscopy (PES) and x-ray absorption spectroscopy (XAS). Covalently bonded nano-networks were formed via radical addition following thermal debromination of the molecules. Networks on the order of 10,000 square nanometres were observed on Au(111), and exhibited thermal stability up to 500 degrees C. Network formation was inhibited on Cu(111) by the significant molecule-substrate interaction, leading to mass transport of Cu atoms and the formation of Cu adatom islands on annealing at 350 degrees C and higher. The Ag and Cu surfaces were sufficiently reacti...
