- A water-soluble, non-sulfur, 2,4-dimethyl-7-amino-1,8-naphthyridine (Z₁) chemosensor was synthesized to fluorescently sense Hg²⁺ in water. The single crystal structure of the sensor confirmed the synthesis results. The detection limit of the sensor towards Hg²⁺ was 8.859 × 10⁻⁸ M, which indicates its high detection sensitivity. The immediate response of Z₁ to Hg²⁺ provided a real-time detection method.
