开发了一种基于 ESIPT 机制和取代-环化-消除级联的用于灵敏检测肼的荧光探针。添加肼后，在 10 分钟内观察到 465 nm 处的荧光强度增强约 50 倍，随后在 375 nm 处观察到荧光强度下降，检测限为 0.147 μM。我们还成功地在 HeLa 细胞中检测到了肼。
A fluorescent probe for sensitive detection of hydrazine based on an ESIPT mechanism and a substitution-cyclization-elimination cascade was developed. After the addition of hydrazine, an approximately 50-fold enhancement in fluorescence intensity at 465 nm was observed and the subsequent decrease at 375 nm was observed in 10 min with a detection limit of 0.147 μM. We also detected hydrazine in HeLa cells successfully.
