The authors report the chem. strategy followed to obtain, in a direct way, nanoparticles of the RbxMn[Fe(CN)6](x+2)/3·nH2O (RbMnFe) Prussian blue analog with the aim of keeping the switching ability of this compound at the nanoscale. The switching property comes from a reversible electron transfer between the Fe and Mn ions and depends on the Rb content in the structure that has to be >0.6. Despite the multifunctionality of this family of compounds and its interest in various applications, no systematic studies were performed to obtain well-defined nanoparticles. This paper relates to such a study. To draw relation between size reduction, composition, and switching properties, a special attention was brought to the determination of the composition through elemental anal. and structure refinement of powder x-ray diffraction patterns together with IR spectroscopy and elemental anal. Several chem. parameters were explored to control both the size reduction and the composition following a direct synthetic approach. The smaller the particles, the lower the Rb content. This observation might prevent the observation of switching properties on very small particles. Despite this antagonist effect, the authors achieved switchable particles of ∼200 nm without any use of surfactant. Also, the size reduction is associated with the observation of the electron transfer down to 52% of Rb in the nanoparticles against 64% in microparticles. This work is of particular interest in processing such nanoparticles into devices. The experimental procedure involved many compounds, such as Rubidiumchloride (cas: 7791-11-9) .
