This work describes the study of molecular junctions embedding the spin crossover complex [Fe(H2B(pz)2)2(phen)] as an active switchable thin film. In these junctions we observed that the spin state conversion causes a gradual increase in the current density, which may be due to a crossover from direct tunneling to multi-step hopping.
