Used as a key intermediate in organic light-emitting diodes (OLEDs), particularly in the electron-transport layer due to its high electron affinity and thermal stability. Its structure supports efficient charge transport and enhances device efficiency in blue-emitting OLEDs. Commonly employed in phosphorescent and thermally activated delayed fluorescence (TADF) OLEDs for display and lighting applications. Also utilized in perovskite solar cells as a hole-blocking or exciton-blocking material to improve device performance. The boronic ester group enables further functionalization via Suzuki coupling, making it valuable in synthesizing complex conjugated systems for optoelectronic devices.
