Used as a key intermediate in the synthesis of organic semiconductors, particularly in the development of blue-emitting materials for OLED (organic light-emitting diode) devices. Its rigid, twisted molecular structure helps suppress aggregation and excimer formation, enhancing emission efficiency. Commonly employed in host materials for phosphorescent OLEDs due to its high triplet energy and good thermal stability. Also utilized in the preparation of hole-transport materials and as a building block in conjugated polymers for optoelectronic applications.
