Used as a key intermediate in the synthesis of organic light-emitting diodes (OLEDs), particularly as a building block for host materials in blue phosphorescent OLEDs due to its high triplet energy and good thermal stability. Also employed in the development of photoredox catalysts for organic transformations, enabling efficient cross-coupling reactions under mild conditions. Its rigid, conjugated structure makes it valuable in designing thermally activated delayed fluorescence (TADF) emitters for energy-efficient displays and lighting. Additionally, derivatives are explored in medicinal chemistry for their potential as antitumor and antimicrobial agents.
