Abstract

A new rhodamine-based derivative modified with allyl group, RPd4, was synthesized as fluorescence-enhanced probe with excellent selectivity for Pd²⁺ and good anti-jamming ability over other cations. The fluorescence intensitiy was linearly proportional to the amount of Pd²⁺ added in μmol/L level with a detection limit of 0.51μmol/L. With the pK_a of 3.81 ± 0.02, it can be used for Pd²⁺ detection in neutral pH range. The colorimetric and fluorimetric response between RPd4 and Pd²⁺ can provide a convenient method for visual detection of Pd²⁺.
