摘要： A turn-on fluorescein-based probe (1) has been successfully developed for the highly sensitive and selective detection of sulfite. The probe exhibits high SO32- selectivity over other common anions and biothiols (Cys, Hcy and GSH), and the detection limit was measured to be 0.55 mu M. Probe 1 exhibited high selectivity towards SO32- with a broad pH (4-9). A significant change from colorless to yellow could be directly observed by the naked eye. Furthermore, living cell imaging results demonstrated its practical application value in biological systems.
