- 摘要：Non-aromatic fluorescent materials with inherent visible light emission have received widespread attention. In this work, a biomimetic fluorescent molecule CA-AEP with a dipeptide structure is introduced.
CA-AEP will emit bright biomimetic fluorescence in aqueous solutions by adjusting the pH, which has
never been reported. This unique luminescent characteristic can be rationalized by the clusteringtriggered emission (CTE) mechanism. In addition, CA-AEP can be used to monitor the maximum dynamic
pH in the alkaline range of aqueous systems. Finally, the cytotoxicity assay to A549 cells showed that CAAEP was non-toxic. Therefore, this work provides a new type of luminogen, which has potential application prospects in the field of environmental monitoring and cell biology.
