A series of fluorene-based conjugated polymers containing the aggregation-induced emissive (AIE)-active tetraphenylethene and dicarboxylate pseudocrown as a receptor exhibits a unique dual-mode sensing ability for selective detection of lead ion in water. Fluorescence turn-off and turn-on detections are realized in 80%–90% and 20% water in tetrahydrofuran (THF), respectively, for lead ion with a concentration as low as 10^-8 m.
