Spin Crossover at the Nanometre Scale

From the development of new methods for the synthesis and patterning of nanometre‐scale thin films and particles, to the first investigations of charge transport and photonic properties, there has been a proliferation of research concerning spin crossover nanomaterials in recent years. Studies have aimed at addressing fundamental questions concerning size‐reduction effects, as well as striving towards practical applications in this important class of bistable molecular materials. This microreview describes the most recent achievements and highlights possible future directions in this field.
