Heterocyclic com pounds and organic light-emitting diode including the same
-
Paragraph 0127; 0152-0156, (2021/07/27)
The present invention relates to a novel heterocyclic compound and an organic light emitting element including the same as a light-emitting material and, more specifically, to a heterocyclic compound having excellent light emission properties, such as a driving voltage, light emission efficiency, and service life, and an organic light emitting element including the same. Since the heterocyclic compound according to the present invention is more stable compared to conventional materials and has the excellent light emission properties for the driving voltage or current efficiency, and service life, the organic light emitting element including the same can be more stably driven in a low-voltage and light emission efficiency can be improved.

-
, (2021/08/11)
The invention provides a preparation method of a diaryl-substituted chlorotriazine OLED intermediate, and the method comprises the following steps: S1, carrying out heating reaction on an aryl nitrile compound and urea in an organic solvent under the action of strong alkali, and carrying out intermolecular ring closing to form a diaryl hydroxyl triazine compound; S2, enabling the diaryl hydroxyl triazine compound obtained in the step S1 to be subjected to a reaction under the action of phosphorus oxychloride, and obtaining the diaryl chlorinated triazine compound. According to the method, the final product can be obtained only through two-step reaction, raw materials are cheap, and expensive catalysts are not needed. The method has the characteristics of low cost, few steps, high yield, few three wastes, easiness in operation, environment friendliness, suitability for industrialization and the like.
