Final Report Abstract

In summary, our study of FePc deposited on different sites reveals (i) repulsive in-plane molecule-molecule interaction, (ii) attractive, site-sensitive out-of-plane molecule-molecule interaction, (iii) site-specific adsorption of the central iron atom on top of the Cl anions, (iv) a strong molecule-Cu(111) interaction with (v) weak directional forces, and (vi) repulsive in-plane molecule-molecule interaction causing deformation of the Pc skeleton. Further investigations to understand this highly relevant molecular model system are required in terms of precise numerical simulations to reveal the different directional repulsive and attractive forces as well as the nature of the adsorption of FePc on NaCI.
