One‐step synthesis of spin crossover nanoparticles using flow chemistry and supercritical CO2. Chemistry - European Journal 2020 vol.26, n°69, p.16286-16290. DOI : 10.1002/chem.202002322 / HAL : https://hal.science/hal-02945200 In the project context : ANR FLOWSWITCH - Flow Chemistry for Room Temperature Switchable Particles - ANR-19-CE07-0022-01 Dataset production context : 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. Here, an innovative and robust template-free continuous process was developed to synthesize nanoparticles of a switchable coordination polymer, including the use of supercritical CO2, aiming at both quenching the particle growth and drying the powder. This all-in-one process offers a 12-fold size reduction in a few minutes while maintaining the switching properties of the selected spin crossover coordination polymer.
