摘要：In view of palladium contaminants and their adverse effects on human health, it is valuable to develop an effective probe for palladium. In this work, a coumarin-based colorimetric and turn-on fluorescent probe, Cou-1, for highly selective and sensitive detection of palladium was designed based on the Tsuji-Trost allylic reaction. Upon the addition of palladium to the solution of probe, the probe gave an emission peak at around 498 nm as well as displayed a selective chromogenic behavior toward palladium from colorless to yellow-green, which could be easily observed by the naked eye. Moreover, compared with typical transition metal canons and other common cations used, Cou-1 showed great selectivity toward palladium. Further, the detection limit toward palladium was calculated to be as low as 17.4 nM. (c) 2015 Elsevier Ltd. All rights reserved.
