CAS.1533406-38-0 3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-9-([1,1′-Biphenyl]-3-yl)carbazole

Carbazole structure is a common hole transport material (HTM) in OLED materials, which can effectively promote the migration of holes in the organic layer. These types of compounds are typically used for hole injection or hole transport in the luminescent layer. In addition, the biphenyl group provides additional π – conjugation, which helps to enhance charge transport capability and strengthen electronic coupling between molecules, optimizing luminescence efficiency. The combination of carbazole and biphenyl skeleton forms a highly rigid molecular structure, inhibits intermolecular aggregation, helps reduce exciton quenching, and improves luminescence efficiency. This stability is crucial for maintaining the performance of OLED devices under long-term operating conditions.
