  Two-dimensional metal-organic porous networks (2D-MOPNs) have been identified
as versatile nanoarchitectures to tailor surface electronic and magnetic
properties on noble metals. In this context, we propose a protocol to
redecorate a ferromagnetic surface potential landscape using a 2D-MOPN.
Ultrathin cobalt (Co) films grown on Au(111) exhibit a well-ordered surface
triangular reconstruction. On the ferromagnetic surface, the adsorbed
2,4,6-tris(4-pyridyl)-1,3,5triazine (T4PT) molecules can coordinate with the
native Co atoms to form a large-scale Co-T4PT porous network. The Co-T4PT
network with periodic nanocavities serves as a templating layer to reshape the
ferromagnetic surface potential. The subsequently deposited C60 molecules are
steered by the network porous potential and the neighboring C60 interactions.
The prototype of the ferromagnetic-supported 2D-MOPN is a promising template
for the tailoring of molecular electronic and spin properties.
