Na+ triggered fluorescence sensors for Mg2+ detection based on a coumarin salen moiety.


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… (More)
