A novel highly active fluorescence chemical sensor (TBQN) for HSO3- was synthesized by Knoevenagel reaction based on triphenylamine-benzothiazole as a new fluorophore. The probe possessed well selectivity toward HSO3- and...
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
