It is important to develop probes for rapid, selective, and sensitive detection of highly toxic benzenethiols in both environmental and biological science. In this work, based on the selective cleavage reaction by benzenethiols under mild conditions, a novel naphthalimide-based fluorescent probe was designed and synthesized for the rapid recognition of benzenethiols with excellent selectivity and anti-interference over other various species including some nucleophilic species, aliphatic thiols, anions and metal ions. The limit of quantification (LOQ) value was 0–4.0 μM and the detection limit could be as low as 10.3 nM. The fluorescence enhancement of this probe upon addition of benzenethiol on test paper and the application of the probe for selective detection in water samples and living cells have been successfully demonstrated.

苯硫酚荧光探针及其在试纸，水样和活细胞中的应用†

在环境和生物科学中，开发用于快速，选择性和灵敏检测高毒性苯硫酚的探针非常重要。在这项工作中，基于苯硫酚在温和条件下的选择性裂解反应，设计并合成了一种新型的萘二甲酰亚胺基荧光探针，用于快速识别苯硫酚，其选择性和抗干扰性优于其他各种物种，包括一些亲核物种，脂肪族硫醇，阴离子和金属离子。定量限（LOQ）值为0–4.0μM，检测限可能低至10.3 nM。已经成功地证明了在试纸上添加苯硫醇后，该探针的荧光增强，以及该探针在水样和活细胞中进行选择性检测的应用。
