英文摘要: In this article, a novel pyrazine-derived hydrazone Schiff-base ligand bearing the quinoline unit (1) has been designed, synthesized and evaluated as a "turn on'' fluorescent chemosensor for Al3+ based on the photoinduced electron-transfer (PET) mechanism and the chelation-enhanced fluorescence (CHEF) phenomenon. The sensor 1 showed remarkably enhanced fluorescence intensity at 488 nm in the presence of Al3+ ion and it also showed high selectivity and sensitivity towards Al3+ ion over a wide range of metal ions in ethanol, for the detection limit of 1 for Al3+ could reach at 10(-7) mol/L.
