A dual‐function fluorescent probe (Probe 1 ) was developed for discriminative detection of Hg²⁺ and N₂H₄. Probe 1 could discriminatively detect Hg²⁺ and N₂H₄ through two different reaction sites, with the mechanism for Probe 1 for Hg²⁺ depending on a desulfurization reaction and for N₂H₄ depending on the Schiff‐base reaction. N₂H₄ had minimal effect on Hg²⁺ detection in dimethyl sulfoxide (DMSO)/H₂O solution, but Hg²⁺ could interfere with N₂H₄ detection in DMSO/buffer solution. Different concentrations of Hg²⁺ and N₂H₄ resulted in different blue shades of Probe 1 test strips, and the shade of blue was different with the same concentration of Hg²⁺ or N₂H₄, as observed under ultraviolet light at 365 nm wavelength.

使用双功能荧光探针判别检测汞（II）和肼。

开发了一种用于区分检测Hg ²⁺和N ₂ H ₄的双功能荧光探针（探针1）。探针1可以通过两个不同的反应位点判别检测Hg ²⁺和N ₂ H ₄，探针1的Hg ²⁺机理取决于脱硫反应，而N ₂ H _4的机理取决于Schiff碱反应。N ₂ H ₄对二甲基亚砜（DMSO）/ H ₂ O溶液中Hg ^2+的检测影响最小，但是Hg²⁺可能会干扰DMSO /缓冲溶液中N ₂ H _4的检测。Hg ²⁺和N ₂ H _4的浓度不同，导致探针1测试条的蓝色阴影不同，而Hg ²⁺或N ₂ H _4的浓度相同时，蓝色阴影在365紫外线下观察到纳米波长。
