Used in organic electronics as a key intermediate for hole-transport materials and host compounds in OLEDs. Its iodophenyl group allows for easy functionalization via cross-coupling reactions, enabling the synthesis of complex conjugated systems. Commonly applied in the development of blue emitters and phosphorescent hosts due to its high triplet energy and good thermal stability. Also employed in photovoltaic devices and perovskite solar cells as a building block for efficient charge-transport layers.
