Recently, growing attention has been paid to the detection of hydrazine (NH 2 NH 2 ) because of its important roles in industrial chemical and high toxicity to human beings. Herein, we have constructed a new colorimetric and far‐red fluorescent probe containing a receptor of 4‐bromobutanoate to selectively detect hydrazine. The probe could detect hydrazine quantitatively in the range of 40–500 μM with the detection limit of 2.9 μM. In addition, the probe could monitor hydrazine by the ratiometric method with a large (185 nm) red‐shifted absorption spectrum, and the color changes from yellow to blue make it as a ‘naked‐eye’ indicator for hydrazine. Consequently, our proposed probe would be of great benefit for monitoring hydrazine in aqueous solution.
