Recovery of PET-quenched Fluorescent Conjugated Polymers with Aza-15-crown-5 as Pendant Groups on Interaction with Ions

Novel conjugated polymers with aza-15-crown-5 as pendant groups, P1 were synthesized by the Sonogashira coupling reaction. The polymer P1 was found to show fluorescence en-hancement response towards Ba2＋. The gradual recovery and turning-point of emission intensity of polymers appeared in the additi...

Summary:Novel conjugated polymers with aza-15-crown-5 as pendant groups, P1 were synthesized by the Sonogashira coupling reaction. The polymer P1 was found to show fluorescence en-hancement response towards Ba2＋. The gradual recovery and turning-point of emission intensity of polymers appeared in the addition of Ba2＋, which provided good evidence for the fluorescence amplification mechanism of conjugated polymers.
