A novel fluoran-based fluorescent probe 2 has been designed and synthesized by using a strategy of blocking the intramolecular photoinduced electron transfer (PET) process. The probe keeps a ring-closed spirolactone structure in aqueous buffer solution. However, the oxidation of the probe by ClO− perturbs a new equilibrium of the structural interconversion between the nonfluorescent spirolactone and
通过使用一种阻断分子内光致电子转移(PET)过程的策略,设计并合成了一种新型的基于荧烷的荧光探针2。探针在缓冲水溶液中保持闭环螺内酯结构。然而,通过CLO探针的氧化-扰乱非荧光螺内酯和荧光开环两性离子,其产生用于CLO高度选择性的荧光探针之间的结构相互转换的新的平衡- 。同时,探针是细胞膜渗透性和可以用作荧光探针用于成像CLO -在活细胞。
