Abstract

Two new Eu‐based ionic liquid systems, [C~4~mim][DTSA] : [Eu(DTSA)~3~] and 2[C~4~mim] [DTSA] : [Eu(DTSA)~3~] were synthesized at 120° under inert conditions from 1‐butyl‐1‐methylimidazolium ditoluenesulfonylamide ([C~4~mim][DTSA]). The identity and purity of the synthesized compounds were confirmed by elemental analysis, IR, Raman, and ^1^H‐NMR spectroscopy. As they solidify below 100° as glasses they qualify as ionic liquids. Fluorescence measurements show that the materials exhibit a strong red luminescence of high color purity. Therefore, they have the potential to be used for optical applications such as in emission displays.
