Abstract
Chemosensor L derived from vitamin B6 cofactor pyridoxal-5-phosphate was investigated for the selective detection of Cu2+ and Fe3+ in aqueous medium. Sensor L formed a 1:1 complex with Cu2+ and displays a perceptible color change from colorless to yellow brown with the appearance of a new charge transfer band at ∼ 450 nm. In contrast, the fluorescence of L was quenched selectively in the presence of Fe3+ without any interference from other metal ions including Cu2+.
