| Abstract: | 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 enhancement 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. |
