The importance of the reaction conditions has been confirmed in this study, where following an on-surface synthesis approach on the same surface and with the same precursor, two different metal-organic frameworks were obtained. The distinction comes from the different synthesis protocol of the controlled growth of both metal-organic nanostructures. Thus, the organic precursors, p-AP molecules, form either a honeycomb or a Kagome metal organic framework on Cu(111), where the presence of adatoms is essential. This research evidences the competition between kinetic and thermodynamic mechanisms in the formation process of metal-organic frameworks on surfaces.
