The abnormal level of Cu2+ or GSH can cause variety of neurodegenerative diseases in humans. Thus, the selective and sensitive detection of Cu2+ and GSH has inspired intensive research efforts in biological sample analysis fields. Herein, an “on–off–on” fluorescent probe based on nitrogen and sulfur...
