A Novel Fluorescent Probe for the Highly Selective and Sensitive Detection of Palladium in Aqueous Medium.

Based on the Pd0 -catalyzed Tsuji-Trost allylic oxidative insertion reaction, we developed a fluorescent probe PdL1 for sensing Pd0 . As expected, probe PdL1 exhibited high selectivity and excellent sensitivity in both absorbance and fluorescence detection of Pd0 in CH3 CH2 OH/PBS (10 mM, pH = 7.4, 6:4, v/v) solution. The detection limit was calculated to be as low as 15 nM, which can meet the selective requirements for practical application.
