Abstract

Abstract : Pyrazine derivative1 for selective detection of Al 3+ with fluorescence enhancement. Abstract : In this study, a novel pyrazine-derived fluorescent sensor bearing the furan unit (1 ) has been designed, synthesized and characterized. This sensor1 showed large enhancement in the fluorescence emission intensity at 517 nm in the presence of Al 3+ and it also showed high selectivity and sensitivity for Al 3+ over other common environmentally and biologically important metal ions, as the detection limit of1 towards Al 3+ could reach 10 −7 mol L −1 . Moreover, the enhancement of fluorescence emission intensity was attributed to the chelation-enhanced fluorescence (CHEF) phenomenon upon complexation of1 with Al 3+ .
