| Abstract: | A novel pyrrole-substituted salicylimine zinc (II) ion complex has been synthesized and evaluated its anion binding affinity. The probe 4 has high selectivity for HSO4 − over other anions in CH3OH:H2O (70:30, v/v) solvent system. The emission intensity of 4 was quenched upon addition of HSO4 − . The probe 4 is highly selective for HSO4 − with a detection limit of 40 nm. Photoinduced electron transfer (PET) is responsible for observed change. The binding affinity of 4 for HSO4 − was further authenticated through ratiometric change in absorbance profile. |
