摘要: An efficient approach to make a fluorescent polymer both photoswitchable and stimuli‐responsive was successfully developed by rationally introducing a photochromic bisthienylethene derivative (BTE) and fluorescent 4‐dicyanomethylene‐2, 6‐distyryl‐4H‐pyran derivative (DPC) units in the side chains via copolymerization. Benefiting from the reversible photocyclization of BTE and the intermolecular Förster Resonance Energy Transfer (FRET) effect from DPC to the closed form of BTE, the emission signatures of the …
