Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLEDs (organic light-emitting diodes). Its rigid, twisted structure helps suppress aggregation and excimer formation, enhancing emission efficiency. Also employed in host materials for phosphorescent OLEDs due to its high triplet energy level. Additionally, it serves as a building block in the synthesis of conjugated polymers for photovoltaic cells and field-effect transistors, contributing to improved charge transport and thermal stability.
