CAS.897921-59-4 N-[4-(1-Naphthyl)phenyl]-4-biphenylamine

Aniline groups have excellent hole transport properties and can promote hole transport in OLED devices. As a hole transport layer (HTL) material, this compound can ensure efficient injection and transport of holes, improve the recombination efficiency of electrons and holes in the luminescent layer, and thus enhance the luminescence efficiency and brightness. In addition, the naphthyl and biphenyl structures form a highly conjugated system, which is crucial for enhancing charge transport capability. Conjugated structures can enhance charge mobility, ensure effective transfer of electrons and holes in OLED materials, and help improve the optoelectronic performance of OLED devices.
