A novel coumarin-derived Cu 2+ -selective Schiff base fluorescent "turn-off" chemosensor CTPE was successfully obtained, which showed an AIE effect. It could identify Cu 2+ by quenching its fluorescence. The lower limit of detection was 0.36 μM. CTPE can act as a highly selective and sensitive fluorescence probe for detecting Cu 2+ .
