By using displacement strategy, a red fluorescence probe based on naphthalene diimide (NDI) can report the presence of sulfide anion with high selectivity and sensitivity, and the detection limit achieved as low as 8.7 μM. The fluorescence response with “on” or “off” state is mainly due to the different kinds of excited states by coordination, which is related to the twisted intramolecular charge transfer (TICT) process.

基于萘二酰亚胺的红色荧光探针通过置换策略选择性检测硫化物

通过使用置换策略,基于萘二酰亚胺(NDI)的红色荧光探针可以高选择性和高灵敏度报告硫化物阴离子的存在,检测限低至8.7μM。“开”或“关”状态的荧光响应主要是由于配位的不同激发态,这与分子内电荷转移(TICT)过程有关。
