摘要：
A polarity-sensitive single-fluorophore and -component system probe An-EA was able to generate tunable luminescence as well as white-light (0.33, 0.36) due to a broad emission spectrum containing monomer and excimer bands that are associated with nanoparticles and aggregated fiber formation, respectively in an aqueous media. In addition to the spectroscopic evidence for monomer and excimer properties in aggregated states, transient absorption spectroscopy was used to investigate charge-transfer properties between donor aniline and acceptor anthracene.
