Used as a key intermediate in organic light-emitting diode (OLED) materials, particularly in the synthesis of electron-transport or host materials for blue-emitting layers. Its boron-containing group (a boronic ester) enables cross-coupling reactions such as Suzuki coupling, allowing incorporation into larger conjugated systems for improved charge mobility and thermal stability. Commonly employed in phosphorescent and thermally activated delayed fluorescence (TADF) devices to enhance device efficiency and lifespan. Also utilized in research for developing new emissive materials in display and lighting technologies.
