Resum:
Spin crossover (SCO) complexes are molecular materials with d4 d7 metal ions that possess a set of properties relevant for practical applications, since they are able to display a spin transition in response to external perturbation, such as a change of temperature, pressure, light irradiation or pulsed magnetic field. To date, many coordination SCO complexes have been studied with different metallic SCO active centres. Among the diverse variety of metal ions, Fe(II) has been the most studied one as, in some cases, the spin transition occurs abruptly, with hysteresis, close to room temperature and is stable over successive cycles. These features make Fe(II) SCO complexes suitable for relevant practical applications in molecular electronics, data storage, display devices, non-linear optics, and photomagnetism. In the present doctoral thesis, several approaches in the field of SCO have been performed.
