Incorporation of open-shell metal-centers into the cationic or anionic species of ionic liquids leads to paramagnetic liquids which show a significant response to an applied magnetic field. The response appears to be dependant on the spin density as well as the viscosity of the liquid. These properties as well as the miscibility of the liquids in different matrices can be changed through variation of cation and anion functional groups. As transparent (though colored) materials, optical features can also be utilized to develop magnetooptical switches.
