文摘

Metal cyanobridged coordination polymers鈥攐r Prussian blue analogues (PBA)鈥攏anoparticles have been synthesized along with a mesostructured MSU-type silica matrix. This synthesis was applied to several M^(II)₃[M鈥?sup>(III)(CN)₆]₂, (M = Co, Ni, Fe; M鈥?= Co, Fe) and a homogeneous distribution of PBA nanometric particles was obtained, even at high concentration (>20 wt %) within a silica matrix that exhibits long-range order as the result of the concomitant increase in concentration of nonionic surfactants templates during the synthesis. The same magnetic behavior as observed for bulk materials was observed with the magnetic PBA nanoparticles and thermal treatment under different atmospheres leads to the formation of bimetallic oxides or alloys, which display magnetic properties.
