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.
三种新型 4-羟基苯并吡喃酮化合物 1-3 已被合成，其端基分别为二甲氨基（1）、溴（2）和氰基（3）。研究了它们在乙腈和水溶液中的光物理性质以及对氰根阴离子的识别性能。由于氰根阴离子与传感器的 O-H 部分之间的氢键反应，这些化合物对氰根阴离子表现出显著的响应，伴随着明显的颜色和荧光变化，因此可以肉眼检测到氰根阴离子。
