Paragraph 0175-0177, (2020/05/01)
The invention belongs to the technical field of organic materials, and provides a compound with a structure as shown in a chemical formula 1 which is described in the specification. In the chemical formula 1, Ar1, Ar2, Ar3 and Ar4 are H or a group as shown in a chemical formula 1-1, and at least one of Ar1, Ar2, Ar3 and Ar4 is the group as shown in the chemical formula 1-1. As the molecular structure of the compound contains a triarylamine group, and contains an electron-donating triphenylamine part and a molecular large conjugated system, the molecule of the compound has the property of intramolecular charge transfer. An organic light-emitting device prepared from the compound has high device efficiency. Compared with the prior art, an organic electroluminescent material disclosed by theinvention has higher stability, so the service life of an organic electroluminescent device is prolonged. In addition, a phenanthrene fused ring derivative is used for structural modification of an electron donor and an electron acceptor respectively, so the photophysical and electrochemical properties of the material can be effectively regulated and controlled, and a luminescent layer material with a narrow energy level band gap is obtained. The invention further provides the organic light-emitting device and an electronic device.
