Paragraph 0172-0175; 0192-0195, (2021/03/03)
The invention provides dianthracene compounds shown in a general formula I in the specification. In the general formula I, L1 and L2 independently represent single bonds, substituted or unsubstituted heterocyclic aromatic groups of C2-C60 or substituted or unsubstituted hydrocarbon aromatic groups of C6-C60; L3 represents a substituted or unsubstituted heterocyclic aromatic group of C2-C60 or a substituted or unsubstituted hydrocarbon aromatic group of C6-C60; R10, R11, R12, R13, R14, R15, R16, R17, R18, R21, R23, R24, R25, R26, R27 and R28 independently represent hydrogen, halogen and substituted or unsubstituted alkyl or alkoxy of C1-C10. The compounds have good luminescence properties, high electron transport capacities and terrific solubility and can be used in luminescent materials, electron transport materials and hole-blocking materials in the electroluminescence field. The invention also provides an organic electroluminescence device at least comprising a pair of electrodes and organic luminescent media between the electrodes. The organic luminescent media at least comprise the dianthracene compounds.

The invention relates to a blue light electroluminescent material and an application thereof. A structural formula of the blue light electroluminescent material is represented by a chemical formula 1shown in the specification. The blue light electroluminescent material provided by the invention has the advantages of high luminous efficiency, high color saturation, good film-forming performance, better thermal stability and the like; compared with a conventional blue host material, the blue light electroluminescent material provided by the invention has the characteristics of high luminous efficiency and long service life of a prepared device; and inventors also find that when a deuterium element is introduced into the material structure, by using the characteristics of the deuterium element, the quantum efficiency, color saturation, service life and the like can be improved, and at the same time, the material has higher tolerance when used for preparing the device.
