摘要: A catalytic fluorescent probe based on V-shaped bis-coumarin has been designed and synthesized for detection of palladium (Pd). The mechanism the is palladium-catalyzed Tsuji‒Trost reaction process photoinduced electron transfer (PET), which can distinguish detect (0, +2/+4) in different valence states under conditions. fluorescence intensity enhances after adding about 10 min at room temperature. limit (LOD) as low 40.0 nM (4.2 ng/g), it good selectivity high sensitivity. Apart from that, successfully applied to environmental waters.
