A novel double target sensor based on diarylethene for the detection of Al³⁺ and Zn²⁺ has been synthesized successfully. Its photochromic and fluorescent behaviors have been investigated systematically by the stimulation of UV/vis lights, Al³⁺, and Zn²⁺ in methanol solution. The sensor exhibited excellent selectivity and sensitivity towards Al³⁺ and Zn²⁺, respectively. The 1:1 stoichiometry between the sensor and Al³⁺/Zn²⁺ was verified by Job's plot and ESI-MS analysis. Moreover, the limits of detection for Al³⁺ and Zn²⁺ were 8.99 × 10⁻⁹ mol L⁻¹ and 3.53 × 10⁻⁸ mol L⁻¹, respectively. Finally, the sensor could be used to detect Al³⁺ and Zn²⁺ in practical water samples with high accuracy.
