Abstract

A new chemosensor, N′-[(2-hydroxyphenyl)methylidene]imidazo[1,2-a]quinoline-2-carbohydrazide (L2), was developed, which could detect Al³⁺ in DMSO/H₂O HEPES buffer and Zn²⁺ in EtOH/H₂O HEPES buffer. The chemosensor exhibits high selectivity and sensitivity for sensing Al³⁺ and Zn²⁺ with a fluorescence "turn-on" mode.
