Chemical structures of investigated 4,5-dialkylated imidazolium-based RTILs. The imidazolium RTILs are abbreviated as Cn-IR·R’A, where n represents the number of carbon atoms in each alkyl chain, I the imidazolium, R the substituent at the N-position, R’ the substituent at the 2-position and A the anion.
