Paragraph 0104-0106, (2021/03/23)
The invention relates to compounds and application thereof. The compounds have a structure represented by a formula (I) in the specification. The compounds are applied to an organic electroluminescentdevice. The organic electroluminescent device comprises a first electrode, a second electrode and at least one organic material layer interposed between the first electrode and the second electrode,wherein at least one organic material layer comprises any one or a combination of at least two selected from the compounds as shown in the formula (I). According to the boron-containing compounds provided by the invention, at least one substituted or unsubstituted C6-C30 aryl group is fused on carbazole, so a conjugate plane is enlarged, electron delocalization is more obvious, a HOMO energy levelis shallower, and a LUMO energy level is deepened, thereby improving the charge transmission performance of a material, balancing carrier transmission, and effectively reducing voltage and improvingluminous efficiency. The compounds are applicable to organic electroluminescent devices.
