Paragraph 0058-0063, (2021/06/06)
The invention provides a compound, application thereof and an organic electroluminescent device. The compound has a structure shown in the specification. Boron atoms contained in the compound have a resonance effect with other atoms in the same ring, the opposite resonance effect on para-position positions of the boron atoms can be enhanced, HOMO and LUMO tracks can be obviously separated through the effect, and therefore the compound has the thermal activation delayed fluorescence property. Meanwhile, the introduction of an electron withdrawing group Rn is beneficial to the adjustment of the energy level of the compound so as to adjust the charge distribution of the compound and is beneficial to further delocalized distribution of electrons, so that the fluorescence quantum yield of the compound is improved, and the compound is favorably used as a dye; the red shift of the emission spectrum of the compound is further facilitated, so that the compound is matched with the main body material in the light-emitting layer, and the phenomenon that the emitted light is too blue is avoided; and meanwhile, the electron transmission performance of the compound is improved, carrier transmission in a device is balanced, an exciton recombination region is expanded, and the performance of the device is improved.
