The design and synthesis of novel fluorescence sensors for Fe3+ in aqueous media have important prospects for practical applications. In this work, the novel bis-biphenylacrylonitrile bridged with crown ether chains 3a-3c were prepared in yields of 73-80%. Compounds 3a-3c exhibited high fluorescence in aqueous media based on the AIE effect. The sensing abilities for a series of metal ions suggested that the compound 3b possessed the selective detection for Fe3+ in aqueous media with strong fluorescence quenching. The detection limit of compound 3b for Fe3+ was 1.67 × 10-7 M and the sensing mechanism was proposed with the assistance of 1H NMR and MS studies. Compound 3b displayed excellent fluorescence imaging properties with a sensing ability for Fe3+ in living cell systems, indicating the good application prospect for sensing Fe3+ in aqueous media and complex environments.
