A unique colorimetric chemosensor Hy‐bp based on thiosemicarbazide was prepared. Hy‐bp showed an obvious red‐shifted spectrum and unique color change from colorless to deep green only for Fe 2+ . Detection limit for Fe 2+ was 0.34 μM, which is the lowest among those of colorimetric chemosensors previously reported for Fe 2+ in pure aqueous solution. Hy‐bp can be utilized in paper strips and water samples as a colorimetric sensor for detecting Fe 2+ . The sensing mechanism of Hy‐bp for Fe 2+ was demonstrated by UV‐vis spectroscopy, Job plot, FT‐IR and 1 H NMR titrations.
