New imidazolium‐based tunable aryl alkyl ionic liquids (TAAILs) containing the weakly coordinating anion [Ga(C 2 F 5 ) 4 ] − are reported. Some phenyl derivatives in combination with different alkyl chains were investigated with regard to their viscosity, conductivity and electrochemical window. In contrast to gallates with standard cations (EMIM, BMIM) the gallate‐TAAILs are stable even up to high electrochemical potentials. Thus, they are promising candidates as electrolytes in electrochemical applications. More information can be found in the Communication by B. Hoge, T. Strassner, et al. (DOI: 10.1002/chem.202102097).
