A new asymmetrical diarylethene containing a 1 H ‐imidazo [4,5‐ f ][1,10] phenanthroline unit was synthesized. The compound showed typical photochromism and functioned as a notable fluorescence switch upon alternating irradiation with ultraviolet (UV) and visible light. Its closed‐ring isomer could be used as a selective ‘naked‐eye’ colorimetric sensor for Cu 2+ , accompanied by a notable color change from blue to colorless. Furthermore, the compound was found to be selective towards Ca 2+ , Mg 2+ , and Sr 2+ with significant fluorescence changes. On the basis of this characteristic, a logic circuit was constructed by utilizing both light and chemical stimuli as inputs and fluorescence intensity at 487 nm as output.
