Abstract

A isatin based Schiff base sensor, L was synthesized by simple one step condensation method and was characterized by various physico-chemical techniques. Sensor L, exhibited fluorescence turn off response to Cu2+ in DMSO: methanol solvent mixture which was further used to detect S2− with fluorescence turn-on response. On changing solvent mixture from DMSO: methanol to DMSO: water reversal of fluorescence behaviour was observed for Cu2+ and S2−. Also, the in-situ formed L-Cu2+ ensemble showed colorimetric response to S2− at high concentration of sulphide ions in both solvent mixtures. Sensor, L was successfully applied to recognize Cu2+ and S2− in human blood serum with micromolar detection limits.
