Paragraph 0139-0140; 0147-0148, (2021/10/27)
The invention provides a heterocyclic compound and an organic light-emitting device thereof. The heterocyclic compound has high electron mobility, and can effectively balance transmission balance of holes and electrons in a device; meanwhile, the HOMO energy level of the heterocyclic compound is deep, and the holes can be blocked in the light-emitting layer, so that the recombination rate of the electrons and the holes in the light-emitting layer is improved, and the luminous efficiency of the organic light-emitting device is greatly improved; meanwhile, the heterocyclic compound has a high glass transition temperature and can form a uniform and stable film, and the service life of the organic light-emitting device can be effectively prolonged when the heterocyclic compound is used as a hole blocking/electron transport layer material; meanwhile, the heterocyclic compound also has a good refractive index, and can effectively reduce total reflection of light in the device and improve the light extraction efficiency of the device when being used as a covering layer material; and the heterocyclic compound and the organic light-emitting device thereof have a good application effect and industrialization prospect.
