It is critical to develop probes for rapid, selective, and sensitive detection of the highly toxic hydrazine in both environmental and biological science. In this work, under mild condition, a novel colorimetric and off-on fluorescent probe was synthesized for rapid recognition of hydrazine with excellent selectivity over other various species including some biological species, metal ions and anions. The limit of quantification (LOQ) value was 1.5×10-4M-3.2×10-3M (colorimetric method) and 1.5×10-4M-3.2×10-3M (fluorescent method) with as low as detection limit of 46.2μM.

肼的比色和荧光检测具有高灵敏度和出色的选择性。

开发用于快速，选择性和灵敏地检测环境和生物科学中的剧毒肼的探针至关重要。在这项工作中，在温和的条件下，合成了一种新型比色和关闭式荧光探针，用于快速识别肼，与其他一些物种（包括一些生物物种，金属离子和阴离子）相比，具有出色的选择性。定量下限（LOQ）为1.5×10-4M-3.2×10-3M（比色法）和1.5×10-4M-3.2×10-3M（荧光法），检出限低至46.2μM。
