Description 1476-1483
Four ionic salts of N, N-disulfodiisopropylammonium cation with complex anionic speciation of metal chlorides such as [FeCl4]-, [NiCl4]2-, [Zn2Cl6]2-/[Zn4Cl10]2-, [CoCl4]2-/[CoCl3]- have been synthesized and characterized with FTIR, NMR, TGA, Raman and electronic spectra. Comparative Brønsted and Lewis acidic strength of the salts have been assessed for catalytic uses in organic reactions via UV-visible Hammett plot and FTIR spectra using pyridine as probe molecule. Band gap values obtained from Tauc plot present their semiconductor behavior to design ionic liquid-based photo catalysts in future.
