Paragraph 0041; 0046-0047; 0048-0049, (2021/06/22)
The invention relates to a compound for organic luminescence. The structure of the compound is shown as a formula (I), Ar1 and Ar2 are respectively and independently selected from hydrogen or an electron donating structural unit, but Ar1 and Ar2 are not hydrogen at the same time. The compound for organic luminescence is a thermally activated delayed fluorescent material with aggregation-induced emission property, is simple in process, easy to purify and high in yield, and can adjust the thermal property, luminescence property and the like of a final product by introducing different groups. When the material is applied to an organic electroluminescent device as a luminescent layer material, the manufactured device has long service life and can meet the requirements of panel manufacturing enterprises.
