A novel 100% aqueous solution near-infrared ratiometric fluorescent CN- probe based on 1,4-dihydropyridines, with a large fluorescent emission peak shift.

1,4-Dihydropyridines are a class of drugs with a wide range of biological activities and pharmacological effects. However, there are few reports on its optical activity, especially its application on fluorescent CN probe. In this experiment, we designed and synthesized a fluorescent probe based on 1,4-dihydropyridines to detect CN.
