Used as a key intermediate in the synthesis of advanced organic semiconductors and liquid crystal materials. Its rigid biphenyl-like structure with iodine substituents makes it suitable for cross-coupling reactions, particularly in forming conjugated systems for optoelectronic devices. Commonly employed in the development of organic light-emitting diodes (OLEDs) and thin-film transistors due to its thermal stability and ability to facilitate charge transport. Also explored in medicinal chemistry as a scaffold for radiolabeled compounds, leveraging the iodine atoms for imaging or therapeutic applications.
