Used primarily as an intermediate in organic synthesis, especially in the preparation of polycyclic aromatic compounds for optoelectronic materials. It serves as a building block in the development of organic semiconductors and light-emitting diodes (OLEDs). The bromine functionality allows for further cross-coupling reactions, enabling the construction of complex conjugated systems. Its rigid, fused-ring structure contributes to thermal stability and electronic properties useful in advanced material science. Also explored in the synthesis of ligands for metal-organic frameworks and catalysts.
