“…Such high decomposition temperatures are provided by the use of substituted imidazolium cations in the structure of ILs, as the ILs based on this cation are usually distinguished by rather high decomposition temperatures [ 29 ]. The stability is also enhanced by the use of the Tf 2 N - anion that is one of the most thermally stable anions used for the synthesis of ILs [ 30 ] and siloxane linkers, whose high thermal stability is due to the high stability of the siloxane bond [ 31 , 32 ].…”
