Outline
In-situ pressure-induced phase transition of ionic liquids [Emim][PF6] and [Bmim][PF6] have been studied under high pressure and room temperature by using Raman spectroscopy and high-pressure diamond anvil cell (DAC) apparatus. With the increase of pressure, [Emim][PF6] experiences the solid-solid phase transition at about 0.86 GPa, and [Bmim][PF6] experiences the liquid-solid phase transition at about 0.62 GPa and the solid-solid phase transition at about 1.45 GPa. Furthermore, the decrease of pressure of [Bmim][PF6] has also been discussed in details. Pressure-released Raman spectra shows that the phase transition of [Bmim][PF6] is reversible under pressure up to 2 GPa.
