Used as a key intermediate in the synthesis of organic semiconductors and luminescent materials. It plays a role in the preparation of conjugated polymers for optoelectronic devices such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). The bromine groups allow for further functionalization via cross-coupling reactions, making it valuable in constructing complex aromatic frameworks. Also employed in the development of metal-organic frameworks (MOFs) due to its rigid isophthalate core and reactive sites.
