Used as a key intermediate in the synthesis of organic semiconductors and optoelectronic materials. Its rigid, planar structure enhances charge transport properties, making it valuable in the development of OLEDs (organic light-emitting diodes) and perovskite solar cells. Frequently employed in the design of host materials for blue phosphorescent emitters due to its high triplet energy and good thermal stability. Also serves as a building block in the preparation of functional dyes and photoactive compounds for sensing applications.
