Here we demonstrate the formation of gold porphyrin derivatives via thermally induced chemical transformations of a fluorinated free-base porphyrin, 2H-4FTPP, on a Au(111) surface, which can rarely be accessed via standard solution chemistry protocols. We also provide an accurate description of the mechanisms of on-surface reactions and self-assembly processes, including structural and electronic characterization of intermediates and products using high-resolution scanning probe microscopy with a CO tip supported by a computational study. An initial annealing step at 500 K induces planarization of the adsorbed free base via dehydrogenation and ring-closing reactions that preserve the integrity of the C–F bonds.
