A novel diarylethene‐based ratiometric fluorescent sensor with full symmetric structure, 1o , was designed and synthesized successfully. 1o could identify lysine (Lys) with high selectivity and sensitivity and the fluorescence emission peak was red shifted 85 nm upon addition of Lys, which could realize ratio recognition. It exhibited excellent anti‐interference performance in the presence of various amino acids in CH 3 CN/H 2 O (7/3, v/v) solution. Moreover, the limit of detection of 1o to Lys could reach 0.019 μM based on a good linear range of 0–40 μM. In addition, the fluorescence emission intensity of 1o could be turned off/on by ultraviolet/visible light due to the special structure of diarylethene. A logic circuit was designed with three inputs. The ratiometric fluorescent sensor 1o could be as a new tool and provide a new method for detection of Lys.
