A high selectivity diarylethene sensor for the detection of Cu²⁺ and CO₃²⁻ was designed and synthesized. It not only has good photochromic properties, but also recognizes Cu²⁺ and CO₃²⁻ by colorimetric and fluorescent. When adding Cu²⁺, the diarylethene derivative exhibited an obvious fluorescence quenching, and the absorption spectrum also changed, the solution color was changed from the colorless to yellow. When adding CO₃²⁻, the reaction aroused a distinct change in the absorption spectrum and with the color change from colorless to yellow. In addition, the sensor can be used to detect Cu²⁺ and CO₃²⁻ by the test strips, and it’s very simple and convenient. The probe can also effectively detect Cu²⁺ and CO₃^2- in water samples. Besides, the probe can enter HeLa cells and recognize Cu²⁺ in the cell.

设计并合成了一种用于检测Cu ²⁺和CO ₃ ^2-的高选择性二芳基乙烯传感器。它不仅具有良好的光致变色特性，而且还可以通过比色法和荧光法识别Cu ²⁺和CO ₃ ^2-。添加Cu ^2+时，二芳基乙烯衍生物表现出明显的荧光猝灭，吸收光谱也发生变化，溶液颜色由无色变为黄色。当添加CO ₃ ^2-时，反应引起吸收光谱的明显变化，并且颜色从无色变为黄色。此外，该传感器还可用于检测Cu ²⁺和CO ₃²⁻通过试纸，非常简单方便。该探头还可以有效地检测水中样品中的Cu ²⁺和CO ₃ ^2-。此外，探针可以进入HeLa细胞并识别细胞中的Cu ²⁺。
