Abstract

We have synthesized a new asymmetric chemo-sensor (E)-4-((2-((2-hydroxybenzylid-ene)amino)phenyl)amino)-3-nitro-2H-chromen-2-one (1) based on the combination of 2-hydroxybenzaldehyde and precursor 4-((2-aminophenyl)amino)-3-nitro-2H-chromen-2-one. Receptor 1 showed a selective color change from colorless to yellow in the presence of Cu^{2 +} in aqueous solution. The detection limit (18 μM) of 1 for Cu^{2 +} is lower than that (30 μM) recommended by WHO in drinking water, and sensor 1 could be recyclable simply through treatment with a proper reagent such as EDTA.
