Abstract

Graphical abstract: Highlights: A new fluorescent chemosensor for Al 3+ based on diarylethene unit was synthesized. Photochromism, and fluorescence switch of this diarylethene were investigated. The diarylethene sensor for Al 3+ shows a detection limit of 9.3 × 10 −8 mol L −1 . Abstract: A new fluorescent turn-on chemosensor for Al 3+ based on a diarylethene unit was designed and synthesized. Photochromism, fluorescence switch, and metal ion recognition behaviors of this diarylethene derivative were investigated by absorption and fluorescence emission spectra. It shows an outstanding fluorometric sensing ability toward Al 3+ ion, and the detection limit was measured to be 9.3 × 10 −8 mol L −1 via fluorescence methods. Based on these interesting properties, a combinational logic circuit was constructed successfully.
