Brief Description

Project brief description

In the view of recent experimental developments [8, 9] the single layers of polymeric metal-phtalocyanine (M-Pc) [8] or porphyrin layers (Pp) [9] are good candidates to practical applications. To mention few arguments, we recall that the fabrication of 2D layers by using heating evaporator was proved to be feasible on thin insulating films [8] with the control of the layer's growth by the temperature variation only [9]. On the other hand the properties of Co-Pc multilayer were investigated experimentally, showing exciting properties [10, 11].

To minimize the presence of defects in covalent networks and to steer the on-surface synthesis toward desired structures is required a detailed understanding of the influence of adsorption energies, diffusion barriers, and lateral interactions of molecular precursors, all of which depend on the substrate atomic environment, symmetry, and chemical nature. Up to date, there exists little experimental and computational insight into the role of the substrate in on-surface chemical routes toward 2D covalent networks [7]. Available studies are focused mainly on the properties of the free molecules and 2D sheets (i.e. no interaction with the surface is taken into account) [12, 13]
