Abstract

Graphical abstract: Highlights: This paper reports a new diarylethene with a hydralazine unit that was designed and synthesized for the first time. The diarylethene could act as a fluorescent sensor for Zn 2+ and HSO4 − . The diarylethene also could be used to construct molecular logic circuits. Abstract: A new photochromic diarylethene derivative with a hydralazine unit was designed and synthesized. It was not only acted as a Zn 2+ sensor with the fluorescent color change from dark blue to bright orange, but also acted as a fluorescent sensor for HSO4 − with the fluorescent color change from dark blue to bright blue. Furthermore, the derivative also exhibits multi-addressable switching properties by the stimulations of lights and chemical reagents. Based on these characteristics, two combinational logic circuits were constructed with the emission intensity as the output signals, and the UV/vis lights, chemical species as the input signals.
