Abstract

Abstract: A fluorescent hydrazine hydrate probe (DMA) based on 1, 4‐dihydropyridine derivatives was designed and synthesized. The fluorescence emission peak of this probe is in the near‐infrared region (667 nm), which has good selectivity to hydrazine hydrate and low detection limit (11 nM). Importantly, the probe exhibits aggregation‐induced emission (AIE) characteristics. In addition, the probe is prepared with a portable test paper to realize the identification of hydrazine hydrate in the solution and the quantitative detection of hydrazine hydrate gas. Abstract : A near infrared hydrazine hydrate fluorescent probe with aggregation‐induced emission (AIE) effect was prepared based on 1, 4‐dihydropyridine. The probe has good selectivity and low detection limit. Based on its AIE luminescence properties, we also prepared a strip for sensing hydrazine vapor.
