合成了三种具有检测胺能力的紫罗碱衍生物。与胺相互作用后,肉眼可以直接观察到紫罗碱衍生物与胺之间的电子转移和电荷转移引起的快速颜色变化。有了氟取代基,这些紫精衍生物对胺的检测灵敏度显着增强,达到ppm水平。
Three viologen derivatives with the ability to detect amines were synthesised. Upon interacting with amines, a rapid colour change caused by electron transfer and charge transfer between viologen derivatives and amines can be directly observed by naked eyes. With fluorine substituents, the detection sensitivity of these viologen derivatives for amines is remarkably enhanced to reach the level of ppm.
