摘要

Abstract

Novel conjugated polymers with aza-15-crown-5 as pendant groups

were synthesized by the Sonogashira coupling reaction. The polymer

was found to show fluorescence enhancement response towards Ba

. The gradual recovery and turning-point of emission intensity of polymers appeared in the addition of Ba

which provided good evidence for the fluorescence amplification mechanism of conjugated polymers.
