Abstract
A novel turn on/off rhodamine 6G based fluorescent probe has been developed for selective detection of Au and Pd complexes in aqueous acidic solutions utilizing rhodamine spirolactam ring-opening process. Rhodamine derivatives have been widely used as versatile platforms for fluorescent probes. The newly designed probe reacts with [AuCl4]- and [PdCl4]2- to generate a product that has distinctly different optical properties. The probe undergoes a remarkable change in its absorption and emission spectrum upon addition of Au and Pd complexes that is associated with a discoloration and quenching of probe fluorescence. The probe exhibits near linear signal response and allows determination of Au and Pd content in aqueous solutions from 0.1 μM.
