, (2020/08/29)
The invention relates to the technical field of display, in particular to a boron-nitrogen heteropolyaromatic ring compound and application thereof. The boron-nitrogen heteropolyaromatic ring compoundhas a structure as shown in a formula I, the compound is based on interaction between a boron-nitrogen structural unit and a surrounding aromatic ring or heteroaromatic ring. The boron-nitrogen heteropolyaromatic ring compound has higher glass transition temperature, higher and balanced charge mobility and more suitable single-triplet state energy, and when the boron-nitrogen heteropolyaromatic ring compound is used as a light-emitting main body material of an organic light-emitting device, the light-emitting efficiency of the device can be greatly improved, and the working voltage of the device is effectively reduced.
