The present subject matter relates to fluorescent compounds that have aggregation-induced emission (AIE) characteristics and tunable emission colors. The emission range of these compounds covers the whole visible region and extends to the near infrared (NIR) area. The compounds can be utilized as bio-probes for lipid droplet (LD) -specific imaging with excellent image contrast to the cell background. Additionally, the high brightness and homology of these compounds endow them with excellent performance for visualizing cell fusion. Further, upon exposure to white light irradiation, the compounds can generate reactive oxygen species (ROS) with high efficiency. As such, the compounds can be effective in photodynamic ablation of cancer cells.
