Abstract

Stable aqueous dispersions of spin-crossover (SCO) doped [Fe^II(Htrz)₂(trz)](BF₄) nanoparticles (NPs) were prepared by using water-soluble polyvinylpyrrolidone (PVP) as protecting polymer. The metal or ligand substitution percentage regulated the ultra-small size and morphology of the NPs. At the same time, the colloidal dispersions showed a complete conversion of the LS state to the HS state of the Fe^II ion.
