      abstract     = {Many applications of molecular layers deposited on metal
                      surfaces, ranging from single-atom catalysis to on-surface
                      magnetochemistry and biosensing, rely on the use of thermal
                      cycles to regenerate the pristine properties of the system.
                      Thus, understanding the microscopic origin behind the
                      thermal stability of organic/metal interfaces is fundamental
                      for engineering reliable organic-based devices. Here, we
                      study nickel porphyrin molecules on a copper surface as an
                      archetypal system containing a metal center whose oxidation
                      state can be controlled through the interaction with the
                      metal substrate. We demonstrate that the strong
                      molecule–surface interaction, followed by charge transfer
                      at the interface, plays a fundamental role in the thermal
                      stability of the layer by rigidly anchoring the porphyrin to
                      the substrate. Upon thermal treatment, the molecules undergo
                      an irreversible transition at 420 K, which is associated
                      with an increase of the charge transfer from the substrate,
                      mostly localized on the phenyl substituents, and a downward
                      tilting of the latters without any chemical modification.},
