Based on hydrolysis reaction by Cu²⁺ and intermolecular hydrogen bond, a dual functional colorimetric probe, a novel 1,8-naphthalimide derivative was designed and synthesized for Cu²⁺ and F⁻ naked-eye recognition with high sensitivity and excellent selectivity. The probe can detect Cu²⁺ and F⁻ quantitatively in concentration range of 0–16.7 μM and 0–23.3 μM, and the detection limit could be as low as 370 nM for Cu²⁺ and 720 nM for F⁻. The detection of F⁻ on chromatography plates and the preliminary application of 1 to detect fluorine contents in several kinds of toothpaste, tap water and Eyebrow Lake have been successfully demonstrated.
