Abstract

Abstract : The new sensor containing oxime-ether can detect Pd 2+ with high sensitivity and high selectivity in aqueous medium. Abstract : A new coumarin-based fluorescent probe (P ) has been developed for visual detection of Pd(ii ) ions, based on a striking color change from green to yellow and significant fluorescence quenching in the presence of Pd(ii ) ions. The probe shows high sensitivity and selectivity and a rapid response time to Pd(ii ) ions in aqueous medium, with a detection limit as low as 4.0 × 10 −8 M. Fluorescence microscopy imaging of HeLa cells showed that this fluorescent probe is effective for detecting intracellular Pd(ii ) ions.
