Abstract

An efficient “turn on” fluorescence chemosensor Schiff base LH based on the combination of 2-Hydroxy-5-(p-tolyldiazenyl)benzaldehyde and N-(3-Aminopropyl)imidazole was prepared and characterized then evaluated for its selective fluorescent sensing of Cu 2+ amongst other metal ions. The CdbndN isomerization inhibition process induced by the Cu 2+ binding warrants the chelation-induced enhanced fluorescence (CHEF) effect. In addition, the detection limit sensing of LH for Cu 2+ was found to be 1.8 × 10 −6 M that is below the WHO recommendation level (20 μM) for drinking water. © 2019 Elsevier B.V.
