In this work, a simple one-step reaction was used to obtain a novel -fused ring based compound . According to the UV–vis absorbance, fluorescence spectra tests, compound has a good selectivity to the detection of Fe and Fe, thus it can be further developed into the probe of Fe and Fe. After the addition of Fe and Fe, the solution (1,4-Dioxane/HO, v/v = 9:1) is turned yellow and its fluorescence is decreased. Based on the results of Job's plot and HRMS spectra, the possible sensing mechanism is proposed as the formation of complexes. As calculated, the limit of detection of on Fe is 0.203 µM while on Fe is 0.331 µM. Noteworthily, probe can response quickly (within 10 s) to Fe and Fe. In addition, probe can be further processed into portable test strips for visual identification of Fe and Fe.

新型N稠环有机分子探针的合成及其铁检测

在这项工作中，使用简单的一步反应获得了一种新型稠环基化合物。根据紫外可见吸光度、荧光光谱测试，化合物对Fe和Fe的检测具有良好的选择性，因此可以进一步开发为Fe和Fe的探针。添加Fe和Fe后，溶液（1,4-二恶烷/H2O，v/v=9:1）变成黄色，荧光减弱。根据乔布图和 HRMS 谱的结果，提出了可能的传感机制为复合物的形成。根据计算，Fe 的检测限为 0.203 µM，Fe 的检测限为 0.331 µM。值得注意的是，探针可以对 Fe 和 Fe 快速响应（10 秒内）。此外，探针还可进一步加工成便携式测试条，用于目视识别Fe和Fe。
