文摘A new coumarin derivative C2 was constructed to act as a highly effective turn-on fluorescent probe for Cu^(2+)ions.The introduction of Cu^(2+)could lead to the hydrolytic cleavage of the phenylhydrazone moiety in C2 and the transformation into strongly fluorescent aldehyde C1.Probe C2 could recognize Cu^(2+)through a marked fluorescence enhancement with the detection limit as low as 150 nmol/L.By virtue of this unique catalytic hydrolysis reaction,compound C2 displayed highly selective response toward Cu^(2+)over other common ions even in the presence of excessive competitive ions.Furthermore,there was a good linear relationship between the intensity change and the concentration of Cu^(2+)ions,which was beneficial for the exactly quantitative detection.Especially,the efficient detection of Cu^(2+)with C2 for the practical application was successfully performed in gas-generating agents detection.
