Used as a key intermediate in organic synthesis, particularly in the preparation of conjugated materials for optoelectronic devices. Its iodine substituents allow for further functionalization via cross-coupling reactions, making it valuable in constructing complex aromatic systems. Commonly employed in the development of organic semiconductors, sensors, and luminescent materials due to its rigid, twisted structure that can exhibit aggregation-induced emission (AIE) properties. Also utilized in pharmaceutical research for building blocks where steric bulk and halogen bonding are important.
