Used as a hole-transporting material in organic light-emitting diodes (OLEDs), this compound helps improve device efficiency and stability. Its large, rigid molecular structure supports high glass transition temperature, which enhances thermal stability in thin films. The triphenylsilyl and fluorene groups contribute to good solubility and film-forming properties, making it suitable for solution-processed OLEDs. It is particularly effective in blue-emitting OLEDs where balanced charge transport is critical. Also explored in perovskite solar cells as an interfacial layer to improve charge extraction and device performance.
