A colorimetric fluorescent probe with fluorescence emission feature sensitive to SO derivatives, i.e. bisulfite (HSO) and sulfite (SO), was developed based on the HSO/SO-mediated nucleophilic addition reaction of the probe that. This probe exhibited SO sensing ability with detection limit down to 46 nM and desired selectivity over other reference anions and redox species. The preliminary fluorescence bioimaging experiments have validated the practicability of the as-prepared probe for SO derivatives sensing in living cells.
基于探针的 HSO/SO 介导的亲核加成反应，开发了一种对 SO 衍生物（即亚硫酸氢根（HSO）和亚硫酸根（SO））具有荧光发射特征敏感的比色荧光探针。该探针对 SO 具有传感能力，检测限低至 46 nM，对其他参考阴离子和氧化还原物种具有理想的选择性。初步的荧光生物成像实验验证了所制备的探针在活细胞中对 SO 衍生物传感的实用性。
