Název v původním jazyce
Surface-mediated spin locking and thermal unlocking in a 2D molecular array
Popis výsledku v původním jazyce
Molecular devices may take advantage of surface-mediated spin state bistability. Whereas different spin states in conventional spin crossover complexes are only accessible at low temperatures, and the lifetimes of the high-spin state are relatively short, a different behavior exhibited by prototypical nickel phthalocyanine is shown here. Direct interaction of the organometallic complex with a copper metal electrode mediates the coexistence of a high spin and a low spin state within the 2D molecular array. The spin state bistability is extremely non-volatile and it originates from the surface-induced axial displacement of the nickel cores. Spin state unlocking and the full conversion to the low spin state are only possible by annealing. This spin state transition is accompanied by distinct changes in the molecular electronic structure that might facilitate the state readout at room temperature, as evidenced by valence spectroscopy.
