Abstract: A series of bis(trifluoromethylsulfonyl)imide hydrophobic monocationic ionic liquids (ILs) with alkyl and siloxane substituents in the imidazolium cation were synthesized and their physicochemical properties were studied. The effect of the substituent nature in the imidazolium cation on the properties of the synthesized ILs was studied. The ILs obtained are characterized by a working temperature range from −70 to 300 °C, viscosity values in the range of 65–184 cSt (30 °C), and surface tension ranging from 23 to 31 mN m−1 (20 °C), being promising lubricants for modification of hydrophobic solid surfaces.
