Abstract

Abstract : A novel multi-responsive fluorescence sensor based on a diarylethene derivative with a 4, 6-dimethylpyrimidine unit was developed for Zn 2+ detection. Abstract : A novel turn-on mode fluorescent diarylethene containing a 4, 6-dimethylpyrimidine unit was developed to fluorescently sense Zn 2+ . Its multiple-responsive properties induced by Zn 2+ /EDTA and ultraviolet/visible light have been systematically studied. The fluorescence sensor could efficiently detect Zn 2+ with a 10 times enhancement of emission intensity and fluorescence color change (dark-green). In addition, the sensor showed clear discrimination from Cd 2+ . The limit of detection of the sensor was measured to be 8.48 × 10 −8 mol L −1 for Zn 2+ . Finally, a molecular logic circuit was fabricated with the emission at 528 nm as the output signal and light and chemical stimuli as input signals.
