4-Carbazol-9-yl-N,N-bis(4-carbazol-9-ylphenyl)aniline(CAT: M440027) is a multifunctional carbazole–triphenylamine derivative designed as a high-performance host and hole-transport material in organic optoelectronic devices. Its tri-cabazole-substituted structure provides excellent thermal and morphological stability, high triplet energy, and efficient hole mobility. Widely applied in organic light-emitting diodes (OLEDs), it serves as an effective host for phosphorescent and thermally activated delayed fluorescence (TADF) emitters, enabling balanced charge injection, reduced exciton quenching, and extended device lifetimes. With strong film-forming properties and compatibility with multilayer architectures, this compound enhances brightness, efficiency, and color purity in advanced OLED displays and lighting applications.
