Tunable AICPL of ( S )‐Binaphthyl‐Based Three‐Component Polymers via FRET Mechanism

Five three‐component chiral polymers incorporating ( S )‐1,1′‐binaphthyl, tetraphenylethene (TPE) and fluorene moieties are designed and synthesized by Pd‐catalyzed Sonogashira reaction. All these polymers show obvious aggregation induced emission enhancement response behavior in the fluorescence emission region of 460–480 nm. Interestingly, three of them show aggregation‐induced circularly polarized luminescence (AICPL) signals in tetrahydrofuran–H 2 O mixtures. Most importantly, these AICPL signals can be tuned by changing the molar ratios of TPE and fluorene components through fluorescence resonance energy transfer and give the highest glum = ±4.0 × 10 −3 . This work provides a novel strategy for developing AICPL‐enhanced materials.
