设计了胺功能化α-氰二苯胺衍生物（Z)-2-（4-氨基苯基）-3-（4-丁氧基）苯基）丙烯腈（ABA）和(Z)-3-（4-丁氧基）-2-[4-（丁胺基）苯基]丙烯腈（BBA），用于特异性识别环境和生物污染物苦味酸（PA）。在化学传感器和PA之间形成的1:1的主客体配合物增强了荧光猝灭，从而在水相和固相中实现了敏感和选择性的检测。
Amine-functionalized α-cyanostilbene derivatives (Z)-2-(4-aminophenyl)-3-(4-butoxyphenyl)acrylonitrile (ABA) and (Z)-3-(4-butoxyphenyl)-2-[4-(butylamino)phenyl]acrylonitrile (BBA) were designed for specific recognition of picric acid (PA), an environmental and biological pollutant. The 1:1 host-guest complexes formed between the chemosensors and PA enhanced fluorescence quenching, thus leading to sensitive and selective detection in aqueous media and the solid phase.
