Ordering spins on surfaces offers significant promise for spintronic, magnetic, magnetoelectric, and magneto-optic technologies. One effective approach is to employ spin-active centers embedded within molecular frameworks capable of self-organizing on surfaces. Porphyrins, with their exceptional chemical versatility and tunability, stand out as particularly suitable candidates for this purpose. Various strategies can be used to achieve such spin ordering, including molecular self-assembly, metal-ligand coordination, and on-surface synthesis involving the formation of C-C bonds. In this work, we present the specific strategies we use to organize spins on surfaces and examine how these methods influence long-range magnetic ordering.
