This work focuses on the growth and characterization of three different transition metals (Mn, Fe and Co) upon selected molecular networks under ultra-high vacuum conditions. The resulting self-assembled structures are characterized by means of Scanning Tunneling Microscopy (STM) and Low Energy Electron Diffraction (LEED). We use a Cu(111) monocrystal as substrate and generate two well-characterized and extended molecular networks that are partially covered or disrupted by the addition of the transition metals. From the highly resolved STM study we can study their mutual interaction and we detect structures that vary from regular nanodots to one dimensional chains.
