A coumarin-based fluorescent probe for the fast detection of Pd0 with low detection limit

We design a fluorescent probe for the detection of palladium with the high sensitivity and selectivity. The probe shows nonfluorescence when connected with allyl carbonate ester which destroys the ICT system. The effect of palladium to the probe can change the structure. As a result, the fluorophore is exposed and it shows fluorescence.
