9‑Aryl-3-aminocarbazole as an Environment- and Stimuli-Sensitive Fluorogen and Applications in Lipid Droplet Imaging

Environment-sensitive
luminophoric molecules have played an important
role in the fields of smart materials, sensing, and bioimaging. In
this study, it was demonstrated that depending on the substituents,
9-aryl-3-aminocarbazoles can display aggregation-induced emission
and solvatofluorochromism, and the operating mechanism was clarified.
The application of these compounds to lipid droplet imaging and fluorescent
probes for cysteamine was demonstrated.
