Ammonia is a common toxic gas in industrial and agricultural production, which will cause harm to the environment and human health in certain extent. Here, a novel fluorescent probe ()- based on 1,1′-binaphthol (BINOL) was synthesized for real-time, on-site and quantitative detection of ammonia. The mechanism study shows that the functional groups of –CHO and –OH on ()- interact with ammonia, which changes the electronic state of the probe molecule and excites strong fluorescence. A test strip for rapid detection of ammonia was developed, which changed from light yellow to reddish brown under natural light after interacting with ammonia, thus realizing the rapid detection and easy visualization of ammonia. Meanwhile, bioimaging experiments shows that probe ()- can detect exogenous ammonia in cells.

基于BINOL的大斯托克斯快速氨检测荧光探针

氨是工农业生产中常见的有毒气体，会对环境和人体健康造成一定的危害。在此，合成了一种基于1,1'-联萘酚（BINOL）的新型荧光探针（），用于实时、现场、定量检测氨。机理研究表明，()-上的-CHO和-OH官能团与氨相互作用，改变了探针分子的电子态，激发出强荧光。研制了一种快速检测氨的试纸条，与氨相互作用后，在自然光下由浅黄色变为红棕色，实现了氨的快速检测和轻松可视化。同时，生物成像实验表明探针()-可以检测细胞内的外源氨。
