Аннотация:Bis(trifluoromethylsulfonyl)imide dicationic ionic liquids containing disiloxane linkersbetween imidazole cations were synthesized. Their thermal stabilities, melting points, viscosities, andvolatilities in vacuo were measured. The possibility of tuning the properties of dicationic ILs byintroducing substituents of different nature into the cation structure is shown.
