A ratiometric fluorescent probe for determining Pd2+ ions based on coordination.
An aniline-rhodamine-based ratiometric fluorescent probe (RI) was designed and synthesized. , the metal coordinating chromophoric ligand, exhibited high selectivity and sensitivity for Pd(2+) ions with a detection limit of 73.8 nM. This method of Pd(2+) detection had a 10 min response time.
