Used in organic light-emitting diodes (OLEDs) as an emissive layer component due to its efficient luminescent properties. Exhibits blue light emission with high quantum yield, making it suitable for display technologies and solid-state lighting. Also investigated as a photosensitizer in photodynamic therapy for its ability to generate reactive oxygen species under light exposure. Serves as a fluorescent probe in biochemical assays for detecting DNA interactions and monitoring cellular processes. Its rigid acridine core enhances photostability and binding affinity to nucleic acids.
