Three hydroxy aurone compounds as chemosensors for cyanide anions

Huihui Chen; Yunhui Sun; Chuanjian Zhou; Duxia Cao; Zhiqiang Liu; Lin Ma

Three new 4-hydroxy aurone compounds 1-3 with dimethylamino (1), bromine (2) and cyano (3) as terminal group have been synthesized. Their photophysical properties as well as recognition properties for cyanide anions in acetonitrile and aqueous solution have also been examined. These compounds exhibit remarkable response to cyanide anions with obvious color and fluorescence change owing to hydrogen bonding reaction between cyanide anions and the O-H moiety of the sensors, which allows naked eye detection of cyanide anions.
