Paragraph 0075; 0076; 0079-0080, (2019/04/17)
The invention belongs to the technical field of organic photoelectric materials and provides a triarylamine compound and an organic light-emitting device. The compound is in a structure shown as a formula (I). Heteroatoms are introduced into the heterocyclic compound, and intramolecular heteroatoms have factors which determine core HOMO/LUMO level, band gap energy and T1 value. By introduction ofa triarylamine structure at a specific position of the heterocyclic compound, carrier transport is benefited, and a great transmission performance can be achieved. By introduction of a bridging structure, on the one hand, the molecular weight of the compound can be increased, the obtained material is high in glass transition temperature, and crystallization can be prevented, and on the other hand,the compound is distorted to some extent in spatial stereo structure, and accordingly the film forming performance is improved. The organic light-emitting device prepared by adopting the compound asa main material of a light emitting layer has advantages of low driving voltage and high light emitting efficiency, and the triarylamine compound is an organic light emitting material with excellent performances.
