Abstract
A reverse micelle method was used for the synthesis of water-soluble silica hybrid, spin-crossover (SCO) nanoparticles (NPs). MRI experiments provided temperature dependent T2 values, indicating their potential use as smart MRI agents, while lyophilization of NP dispersions in water yielded powders with a preserved but modified thermal hysteretic magnetic profile.
Highlights
A facile approach to prepare silica hybrid, spincrossover water-soluble nanoparticles as potential candidates for thermally responsive MRI agents†

We present the synthesis and spectroscopic characterization of silicon-modified doped NPs based on the already known 1-D SCO coordination polymer [FeII(Htrz)2(trz)] (BF4)
