Novel Diarylethene-Based Fluorescent Switching for the Detection of Al³⁺ and Construction of Logic Circuit.

ABSTRACT: A novel photochromic diarylethene was synthesized successfully containing a phthalazine unit. Its multistate fluorescence switching properties were investigated by stimulating with UV/vis lights and Al³⁺/EDTA. The synthesized diarylethene displayed excellent selectivity to Al³⁺ with a distinct fluorescence change, revealing that it could be used as a sensor for fluorescence identification of Al³⁺, and a logic circuit was constructed by utilizing this diarylethene molecular platform. Moreover, it also exhibited a high accuracy for the determination of Al³⁺ in practical water samples.
