Used in organic light-emitting diodes (OLEDs) as a blue-emitting material due to its favorable luminescent properties. Also serves as a building block in the synthesis of photoreactive compounds and fluorescent probes for biological imaging. Its rigid acridine core enhances stability and electron transport in optoelectronic devices. Additionally, it has been investigated for use in photodynamic therapy owing to its ability to generate singlet oxygen under light irradiation.
