Cas No.7428-91-3 2-Dibenzothiophenamine

Dibenzothiophene has high conjugation and good charge transport properties, while the amine group as an electron donor can further enhance the hole transport performance of the material. Therefore, dibenzothiophene-2-amine can be used as an important intermediate for OLED hole transport materials. The rigid planar structure of dibenzothiophene provides high charge transfer efficiency, while the electron donating properties of the amino group further enhance the hole transport ability. This compound can effectively promote the transfer of holes from the anode to the light-emitting layer in OLED devices, reduce charge loss, and thus improve the luminous efficiency and brightness of the device. In addition, dibenzothiophene has a high electron affinity and can effectively transfer electrons. By adjusting the LUMO energy level of the material, the amino group enables dibenzothiophene-2-amine to exhibit good electronic conductivity when used as an electron transport material. It can be combined with other electronic transfer materials to ensure efficient injection and transfer of electrons in OLED devices.
