A novel Tb(III) complex-based time-resolved luminescent probe, BBPNA-(DO3A-Tb3+)2 (L), was designed and synthesized for the recognition of Cu2+ and sulfide ions in aqueous solutions. The luminescent probe L was efficiently quenched by Cu2+ and displayed “on–off” type luminescence change towards Cu2+. Once combined with Cu2+ to form the non-luminescent L–Cu complex, the L–Cu complex could serve as...
