摘要：

The novel turn-off fluorescent chemosensor for silver ion based on cinnamylidene derivatives of malononitrile trimer with 1,1,3,3-tetracyanopropenide unit was developed. The quenching of fluorescent emission can be observed by naked eye, even in the presence of interference cations. The binding mode turned out to be a 1: 1 ratio as determined using Job plot. Good solubility in water can be applied for the detection of Ag+ in water samples. (C) 2020 Elsevier B.V. All rights reserved.
