A multi-functional fluorescent sensor for Zn2+ and HSO4− based on a new diarylethene derivative

Abstract

A new photochromic diarylethene derivative with a hydralazine unit was designed and synthesized. It was not only acted as a Zn2+ 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.
