A new chemodosimetric probe (1) is reported that selectively detects thiols over other relevant biological species by the turning on of its fluorescence through a Michael type reaction. The fluorogenic process upon its reaction was revealed to be mediated by intramolecular charge transfer, as confirmed by time-dependent density functional theory calculations. The application of probe 1 to cells is
报道了一种新的化学计量探针(1),其通过迈克尔型反应通过开启其荧光来选择性地检测相对于其他相关生物物种的硫醇。如时间依赖性密度泛函理论计算所证实的,荧光反应在其反应过程中被揭示是由分子内电荷转移介导的。还通过共聚焦显微镜检查了探针1在细胞上的应用,并通过对细胞代谢产物的体外LC-MS分析观察到了其半胱氨酸的偏爱。
