Used primarily in organic semiconductor research, this compound serves as a key intermediate in the synthesis of high-performance hole-transport materials for OLED (organic light-emitting diode) devices. Its rigid fluorene backbone and bromine functionality make it ideal for cross-coupling reactions, enabling the construction of conjugated polymers and small molecules used in blue-emitting layers and host materials. The dimethyl and phenyl substitutions enhance thermal stability and film-forming properties, which are critical for efficient and durable electroluminescent devices. It is also employed in the development of materials for perovskite solar cells due to its favorable energy level alignment and morphological stability.
