Switchable materials are increasingly considered for implementation in devices or multifunctional composites leading to a strong need in terms of reliable synthetic productions of well‐defined objects. We report here an innovative and robust template‐free continuous process to synthesize nanoparticles of a switchable coordination polymer, including the use of supercritical CO 2 , aiming at both quenching the particle growth and drying the powder. This all‐in‐one process offered a 12‐fold size reduction in few minutes, maintaining the switching properties of the selected spin crossover coordination polymer.
