A novel fluorescent probe with a high quantum yield (0.41), large Stokes shifts (255nm), and red emission (635nm) was designed to detect all typical oxidation states of palladium species (0, +2, +4) by palladium-mediated terminal propargyl ethers cleavage reaction in water solution without any organic media. The probe showed a high selectivity and excellent sensitivity for palladium species, with a detection as low as 57nM (6.2gL(-1)).
