A highly efficient system that incorporates the instantaneous visualization of the cyanide ion in water was synthesized by keeping the fluorophore system (electron donor) as a julolidine-coumarin conjugate and changing the electron acceptor unit. The probes exhibit a notable color change in normal and UV light. The probe interaction modalities are based on the ICT process. With a detection limit in the nM range, it may preferentially react with cyanide, which is less than the tolerable level of 1.9 μM. According to H NMR data, the probes detect cyanide ions by nucleophilic addition reaction mechanism. Furthermore, current probe successfully determines real resources, including cyanide containing cassava powder, sprouted potatoes and various water samples. Besides the test strips, an electronic Arduino device was also employed to detect the cyanide ion. As such, the developed probes exhibit outstanding practical application with respect to the cyanide ion.
通过将荧光团系统（电子供体）保持为久洛定 - 香豆素共轭物并改变电子受体单元，合成了一种高效的系统，该系统能够实现水中氰离子的即时可视化。这些探针在自然光和紫外光下呈现出显著的颜色变化。探针的相互作用模式基于ICT过程。其检测限在纳摩尔范围内，它可能优先与氰化物反应，该反应程度低于1.9 μM的可耐受水平。根据核磁共振氢谱数据，这些探针通过亲核加成反应机制检测氰离子。此外，当前的探针成功地测定了实际样品，包括含氰化物的木薯粉、发芽的土豆和各种水样。除了测试条外，还使用了电子 Arduino 设备来检测氰离子。因此，所开发的探针在氰离子检测方面展现出出色的实际应用价值。
