Description
Summary:Spin crossover (SCO) iron (II) coordination compounds in the form of nanohybrid SCO@SiO<sub>2</sub> particles were prepared using a reverse micelles technique based on the TritonX-100/cyclohexane/water ternary system. Tetraethyl orthosilicate (TEOS) acts as precursor of both the SiF<sub>6</sub><sup>2−</sup> counter-anion and SiO<sub>2</sub> to obtain Fe(NH<sub>2</sub>trz)<sub>3</sub>(BF<sub>4</sub>)<sub>2−x</sub>(SiF<sub>6</sub>)<sub>x/2</sub>@SiO<sub>2</sub> nanoparticles with different sizes and morphologies while modifying the TEOS concentration and reaction time. The adjustable mixed-anion strategy leads to a range of quite scarce abrupt spin crossover behaviors with hysteresis just above room temperature (ca. 293 K), which is very promising for the integration of these materials into functional devices.
