Paragraph 0110-0112; 0138-0140, (2021/03/05)
The invention relates to an organic electroluminescent compound and application thereof. The organic electroluminescent compound has a structure as shown in a formula I which is described in the specification. The invention provides the novel organic electroluminescent compound. A special condensed ring structure is used as a parent nucleus; the structure has torsion of a certain angle, the hole transport rate is reduced to a certain degree, hole and electron transport rate balance is facilitated, and when the structure is applied to an organic light-emitting device, especially when the structure is used as a light-emitting layer main body material, the device can have high light-emitting efficiency, low driving voltage and long service life.
