Two coumarin salen-based sensors CS1 and CS2 can exhibit a pronounced fluorescence enhancement response toward Mg(2+) as high as 36-fold (CS1) and 111-fold (CS2) in the presence of Na(+) as a synergic trigger. More importantly, the fluorescent color of CS1 was bright green instead of weak yellow after the addition of Mg(2+) and Na(+) together, which can be easily detected by the naked eye.
两种香豆素水杨醛席夫碱传感器 CS1 和 CS2 在钠离子作为协同触发剂存在的情况下，对镁离子表现出高达 36 倍（CS1）和 111 倍（CS2）的显著荧光增强响应。更重要的是，CS1 的荧光颜色在加入镁离子和钠离子后变为亮绿色而不是微弱的黄色，这可以通过肉眼轻松检测到。
