We synthesized a new fluorescent probe 1O by attaching a diarylethene molecule to a functional group. The probe can be used to detect Al and Zn at the same time with high selectivity, and its detection limit is very low. When Al was added, the fluorescence intensity was increased 310 folds, and was accompanied by a fluorescent color change from black to grass-green. Similarly, after the addition of Zn, the fluorescence intensity was enhanced 110 folds, with a concomitant color change from black to yellow-green. Moreover, based on the properties of 1O, we designed a logic circuit, and that also can be used for water sample testing.
我们通过将二芳基乙烯分子连接到一个官能团上合成了一种新的荧光探针1O。该探针可用于同时高选择性地检测铝和锌，其检测限非常低。加入铝时，荧光强度增加310倍，并伴随着荧光颜色从黑色变为草绿色。同样，加入锌后，荧光强度增强110倍，同时颜色从黑色变为黄绿色。此外，基于1O的性质，我们设计了一个逻辑电路，其也可用于水样检测。
