A novel fluorescent sensor on the basis of diarylethene and benzohydrazide unit was successfully synthesized. Its photochromic and fluorescent switching properties have been studied in detail by the irradiation of UV‐visible (UV‐Vis) lights and the stimulus of Zn2+/EDTA. The sensor exhibited high sensitivity and selectivity toward Zn2+ in tetrahydrofuran, which is not interfered by other cations, especially of congener Cd2+. The fluorescence intensity enhanced 84 times along with a 44‐nm blue shift of the emission peak after adding Zn2+. The stoichiometric ratio between the sensor and Zn2+ was 1:1, and the limit of detection (LOD) was calculated as 5.60 × 10−9 mol L−1. Besides, the sensor was applied in the detection of practical water samples with high accuracy.

一种新型的基于二芳基乙烯的荧光传感器，带有苯并酰肼单元，用于检测Zn2 +
成功地合成了基于二芳基乙烯和苯并酰肼单元的新型荧光传感器。通过紫外可见光（UV-Vis）的照射和Zn 2+ / EDTA的刺激，已对其光致变色和荧光转换特性进行了详细研究。该传感器对四氢呋喃中的Zn 2+表现出高灵敏度和选择性，不受其他阳离子（尤其是同源Cd 2+）的干扰。添加Zn 2+后，荧光强度增强了84倍，并且发射峰出现了44 nm蓝移。传感器与Zn 2+的化学计量比为1：1，计算的检出限（LOD）为5.60×10 -9 mol L -1。此外，该传感器还用于高精度的实际水样检测中。
