As a novel ultraviolet (UV) absorbent with excellent performance in UVA section (320 ~ 400 nm), 2-{2-hydroxy-4-[(octyloxycarbonyl)ethylideneoxy]phenyl}-4,6-Bis(4-biphenylyl)-1,3,5-triazine (CGL-479) was synthesized in a simple method with a total yield of 45.3% in four steps. Its outstanding UV absorption capability (λmax = 326 nm, ε max = 4.15×104 L·mol-1 ·cm-1), high thermostability [T5 (the temperature of losing 5% in weight) = 385 °C], and compatibility with polymer materials make it a potential substitute of the traditional UV absorbents.

Paragraph 0041-0042; 0044, (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.
