Abstract

Abstract: A novel diarylethene containing a 5-aminouracil unit was synthesized. Its multi-responsive properties induced by base/acid, UV/Vis lights, and metal ions were investigated in detail. The diarylethene was highly selective towards Al 3+ and Zn 2+ with obvious fluorescence changes and different binding modes. Furthermore, based on the multi-addressable characteristics, two logic circuits were constructed by using both UV/Vis lights and chemical species stimuli as inputs and fluorescence intensity as outputs. Graphical abstract: A new photochromic diarylethene with a 5-aminouracil unit for highly selective affinity to Al 3+ and Zn 2+ was synthesized. The diarylethene could act as a fluorescent sensor for Al 3+ and Zn 2+ and be used to construct molecular logic circuits. Highlights: This paper reports a new diarylethene with an aminouracil unit that was designed and synthesized for the first time. The diarylethene exhibited multi-responsive switch behaviors with the stimuli of lights, base/acid, and metal ions. The diarylethene could act as a fluorescent sensor for Al 3+ and Zn 2+ and be used to construct molecular logic circuits.
