Used as a key intermediate in the synthesis of functional organic materials, particularly in the development of fluorescent dyes and optoelectronic compounds. Its brominated structure allows for further cross-coupling reactions, making it valuable in constructing complex aromatic systems for use in organic semiconductors and sensor technologies. It is also employed in research settings to prepare acenaphthylene-based polymers with potential applications in organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs). Due to its electron-deficient nature, it participates in cycloaddition and condensation reactions to form fused heterocyclic frameworks with biological or photophysical activity.
