A triazole based fluorescence “turn-on” sensor for Al(Ⅲ) and Zn(Ⅱ) ions

A triazole based fluorescence “turn-on” sensor for Al(Ⅲ) and Zn(Ⅱ) ions

A triazole derivative containing trifluoromethyl and diphenol unit was synthesized as a fluorescent ‘turn-on’ chemosensor for Al3+ and Zn2+ ions with high sensitivity, a rapid response time and specific selectivity over other cations. •A fluorescence “turn-on” sensor can selectively detect two metal...

Zusammenfassung:A triazole derivative containing trifluoromethyl and diphenol unit was synthesized as a fluorescent ‘turn-on’ chemosensor for Al3+ and Zn2+ ions with high sensitivity, a rapid response time and specific selectivity over other cations. •A fluorescence “turn-on” sensor can selectively detect two metal ions simultaneously was designed and synthesized.•Upon the addition of metal ions, the fluorescence intensity increased remarkably.•The enhanced fluorescence was probably attributed to the formation of a 1:1 complex.
