Tetrachloroferrate containing ionic liquids: Magnetic- and aggregation behavior

The magnetic behavior of a binary salt of tricaprylylmethylammonium tetrachloroferrate and tricaprylylmethylammonium chloride, [A336][FeCl4]0.73[Cl]0.27, was evaluated. With a magnetic susceptibility of 0.011 emu mol− 1 this binary salt exhibited a remarkable response to an external magnetic field. Dynamic light scattering (DLS) measurements allowed to study the aggregation behavior of [A336][FeCl4]0.73[Cl]0.27 as well as of further magnetic ionic liquids [PR6,6,6,14][FeCl4] and (BMIM)[FeCl4] in ethylacetate and ethanol.

Graphical AbstractThe magnetic behavior of the binary salt tricaprylylmethylammonium tetrachloroferrate and tricaprylylmethylammonium chloride, [A336][FeCl4]0.73[Cl]0.27, was measured. Furthermore, dynamic light scattering measurements (DLS) were applied to study the aggregation behavior of magnetic room temperature ionic liquids [A336][FeCl4]0.73[Cl]0.27, (BMIM)[FeCl4] and [PR6,6,6,14][FeCl4] in organic solvents.Figure optionsDownload as PowerPoint slide
