A novel turn-on fluorescent sensor for Al based on photochromic diarylethene with a 2-hydroxybenzhydrazide unit has been successfully designed and synthesized. The photochromic and fluorescent characteristics were studied methodically in methanol under irradiation using UV/vis light and induced by Al/EDTA. This fluorescent sensor was highly selective toward Al with an obvious fluorescent color change from dark blue to blue. The Job's plot and mass spectrometry (MS) analysis indicate a binding stoichiometry of 1 : 1 between the fluorescent sensor and Al. Moreover, a test strip containing this fluorescent sensor was prepared to allow for the easy detection of Al in water. Finally, a logic circuit was designed using four input signals (In1: UV; In2: vis; In3: Al; In4: EDTA) and one output signal.
一种基于带有2-羟基苯甲酰肼单元的光致变色二芳基乙烯的新型铝离子开启型荧光传感器已成功设计并合成。在甲醇中，通过紫外/可见光照射并由铝/乙二胺四乙酸诱导，系统地研究了其光致变色和荧光特性。该荧光传感器对铝具有高度选择性，荧光颜色从深蓝色明显变为蓝色。Job曲线和质谱（MS）分析表明荧光传感器与铝之间的结合化学计量比为1∶1。此外，制备了含有该荧光传感器的测试条，以便于检测水中的铝。最后，使用四个输入信号（In1：紫外光；In2：可见光；In3：铝；In4：乙二胺四乙酸）和一个输出信号设计了一个逻辑电路。
