•A highly Ga(III) selective chemosensor 1 was synthesized and investigated.•1-Ga complex can be utilized for detection of HSO4− ions.•The sensor showed high selectivity for Ga+3 even in the presence of other interfering metals (Al+3, In+3, Zn+2).•The mechanism of fluorescence was based on the inhibition of excited state intramolecular proton transfer.
A new highly selective turn-on fluorescent chemosensor based on 2′-hydroxyphenylthiazole for the detection of gallium and hydrogen sulfate ions in acetonitrile was synthesized and characterized. The mechanism of fluorescence was based on the inhibition of excited state intramolecular proton transfer (ESIPT). The sensor demonstrated high selectivity for gallium as compared to aluminum and other cations and allowed sequential detection of hydrogen sulfate.
