A new “off-on” probe for Fe3+ based napthalimide modified benzoyl hydrazine derivative was designed and synthesized. The proposed probe P showed good selectivity to Fe3+ compared to other common metal ions and anions. The absorbance of P was proportional to the concentration of Fe3+ in the range of 9.0 × 10-6 to 6.5 × 10-5 M with a detection limit of 3.0 × 10-6 M.
