We reported here the synthesis of a diarylethene with a 2,4-dihydroxybenzoyl hydrazine moiety (1O) for Zn recognition. The compound is easy to prepare with a high yield up to 85%. Compound 1O can act as a highly selective and specific fluorescent sensor for Zn without interference by other common metal ions. The LOD for Zn detection was determined to be 1.28 × 10 mol L. Meanwhile, 1O can be used as a naked-eye detector for the Zn ion with an obvious color change from colorless to olive. Based on the fluorescent properties of 1O, we constructed a logic circuit with four inputs of the combinational stimuli of UV/vis light and Zn/EDTA, and one output of fluorescence intensity.
我们在此报道了一种带有2,4 - 二羟基苯甲酰肼部分（1O）的用于锌识别的二芳基乙烯的合成。该化合物易于制备，产率高达85%。化合物1O可作为锌的高选择性和特异性荧光传感器，不受其他常见金属离子干扰。锌检测的检测限确定为1.28×10⁻⁸ mol/L。同时，1O可用作锌离子的肉眼检测器，颜色从无色变为橄榄色有明显变化。基于1O的荧光特性，我们构建了一个具有紫外/可见光和锌/乙二胺四乙酸组合刺激的四个输入以及荧光强度一个输出的逻辑电路。
