Abstract

A thiourea-based fluorescent chemosensor NADA, (E)-2-(4-(diethylamino)-2-hydroxybenzylidene)-N-(naphthalen-1-yl)hydrazine-1-carbothioamide, has been designed and synthesized. NADA could detect Ga³⁺ through a fluorescent turn-on with a low detection limit (0.29 μM). Importantly, NADA could effectively discriminate Ga³⁺ from Al³⁺ and In³⁺. The binding mechanism of NADA with Ga³⁺ was identified by ESI-mass, NMR titration, and DFT calculations.
