This work presents a detailed investigation of the influence of solid supports on the axial ligand binding properties of cobalt porphyrins. Metal porphyrins and other tetrapyrrole molecules form well-ordered, self-assembled monolayers on solid supports and because of unsaturated character of the metal atom within the macrocycle may form five and six coordinate complexes with axial ligands. Porphyrin chemistry is well understood in the solution environment; however, this knowledge does not always translate to accurate predictions of the behavior of porphyrins confined to a surface.
