- Compound for organic luminescence and application of compound
-
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.

- CARBAZOLE DERIVATIVE, MATERIAL FOR LIGHT EMITTING ELEMENT, LIGHT EMITTING ELEMENT, LIGHT EMITTING DEVICE, AND ELECTRONIC DEVICE
-
An object of the present invention is to provide a carbazole derivative which is useful in manufacturing a substance having resistance to oxidation. Another object is to provide a carbazole derivative which is useful in manufacturing a novel material with high reliability. Still another object is to provide a material for a light emitting element with high reliability. The present invention is a carbazole derivative represented by the following general formula (1) (where each of Ar1 and Ar2 represents an aryl group having 6 to 14 carbon atoms which may include a substitute, Ar1 and Ar2 may be either the same or different, and R in the formula represents hydrogen or an alkyl group having 1 to 4 carbon atoms). In addition, the present invention is a material for a light emitting element which includes a carbazole derivative represented by the following general formula (1) as a substituent.
