EN A sensor that can detect methoxy group in cation part of imidazolium ionic liquid was developed based on Reichardt's solvatochromic dye. The Reichardt's dye incorporated into three ionic liquids: 1-methyl-3-octyloxymethylimidazolium tetrafluoroborate, 1-methyl-3-hexyloxymethylimidazolium bis(trifluoromethylsulfonyl)imide, and 1-methyl-3-octylimidazolium tetrafluoroborate (without oxymethyl group in the structure), has been study by absorption and steady state fluorescence spectra. The striking solvatochromic effect was observed in ionic liquid includes oxymethyl group in the structure.
