A kind of benzofurancarbazole-containing tert-butylbenzidine derivative and application thereof |
| abstract |
The invention relates to a benzofurancarbazole-containing tert-butylbenzidine derivative and an application thereof. The structural formula of the benzofurancarbazole-containing tert-butylbenzidine derivative is as follows [I]: The R substituents are aryl or heteroaryl groups between C6 and C80 and derivatives thereof. The benzofurancarbazole-containing tert-butylbenzidine derivatives are used in organic electroluminescence devices. It can be used as the host material of the hole transport layer or the light-emitting layer of the OLED device. The prepared organic electroluminescent device has obvious improvements in light-emitting time, light-emitting efficiency, and thermal stability, and has good optoelectronic properties. market expectation. |
