Abstract

The invention discloses a compound taking a quinolinone derivative as a core and an application of the compound in an organic electroluminescent device. The compound structurally contains the quinolinone derivative as an electron acceptor, so that transmission of electrons in a light-emitting layer is facilitated. A connected heterocyclic group is an electron donor, so as to facilitate the transmission of holes in the light-emitting layer. Nitrogen atoms in the heteroatom-containing benzoazadione are saturated atoms, have quite strong rigidity and are beneficial to improving the triplet stateenergy level of the parent nucleus compound, and the combination of the electron donor and the electron acceptor can improve the recombination efficiency of excitons, the starting voltage is reduced and the performance of the device is improved. When the compound is used as a light-emitting layer material of the organic electroluminescent device, the current efficiency of the device is greatly improved, and the service life of the device is obviously prolonged.
