OH protected 2-(hydroxyphenyl) benzothiazole (HBT) based ratiometric chemodosimeters have previously been reported to undergo regeneration of excited state intramolecular proton transfer (ESIPT) process upon deprotection. In the current work it is demonstrated for the first time that generation of anion of HBT leads to the optical changes in these types of chemodosimeters rather than regeneration of HBT by using a Hydrazine specific chemodosimeter based on substituted HBT.

脱保护后受保护的基于HBT的化学计量仪的去向：ESIPT的恢复或发光酚的产生？

先前已经报道了基于OH保护的2-（羟苯基）苯并噻唑（HBT）的比率化学计量计在脱保护后经历了激发态分子内质子转移（ESIPT）过程的再生。在目前的工作中，证实为第一次产生阴离子的HBT导致在这些类型chemodosimeters而不是再生的光学变化HBT通过使用基于取代的肼特定chemodosimeter HBT。
