本文介绍了一种新型的检测芥菜及其模拟物的传感器，该传感器采用苯并噻唑对红石发色团进行功能化，然后将螺内酰胺进行硫代化。合成的化学剂量计（RHBT）在SM及其模拟刺激下表现出明显的黄绿色荧光增强和从无色到紫红色的显色变化，这是基于硫内酰胺的s -烷基化和rhodol苯并噻唑的激发态质子转移（ESIPT）协同作用诱导rhodol的螺硫内酰胺环打开。此外，化学剂量计在常温下可快速检测溶液、土壤和空气中的SM及其模拟物，表明其在芥菜现场检测中的潜在应用前景。
In this paper, we introduced a new sensor for detecting sulfur mustard (SM) and its simulant through the functionalization of a rhodol chromophore with benzothiazole, followed by thionation of the spirolactam. The synthesized chemodosimeter (RHBT) exhibited an obvious green-yellow fluorescence enhancement and chromogenic change from colorless to fuchsia in the presence of SM and its simulant stimuli, which is based on the spirothiolactam ring opening of rhodol induced by the synergy of S-alkylation of thiolactam and the excited state intramolecular proton transfer (ESIPT) of rhodol benzothiazole. Furthermore, the chemodosimeter was successfully demonstrated for the rapid detection of SM and its simulant in solution, soil and air at ambient temperature, indicating its potential application for on-site detection of sulfur mustard.
