Abstract: | A new fluorescent turn-on chemosensor for Al3+ 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 Al3+ 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. |
