A new diarylethene derivative containing a hydrazinylpyridine unit has been synthesized. The diarylethene derivative was highly selective and sensitive to Cd(2+ )and Zn2+ with significant fluorescence emission and color changes. Moreover, its multi-controllable photochromism and fluorescent switching characters were studied systematically with various stimuli (UV/vis lights and chemicals) in methanol solution. Based on the multi-addressable fluorescent switching characters, a combinational logic circuit was constructed by using the fluorescence emission intensity at 480 nm as output signal, the UV/vis lights, Cd2+, and EDTA as input signals.
