Embodiment 1

[0092] Embodiment 1: the synthesis of compound 1:

[0093]

[0094] In the three-necked flask, nitrogen was introduced, 0.025mol of intermediate A1, 100ml of DMF, 0.03mol of intermediate B1, 0.0002mol of palladium acetate were added, stirred, and then 0.03mol of K 3 PO 4 Aqueous solution, heating and reflux reaction for 12 hours, sampling point plate, the reaction is complete. Cool naturally, pour the reaction solution into a 500ml beaker, add 200ml distilled water, and carry out mechanical stirring for 10min, then the mixed solution is suction filtered, the filter cake is rinsed once with 100ml distilled water, and then rinsed with 100ml ethanol to obtain Pale yellow solid powder. Finally, the light yellow solid powder was purified by silica gel column with the eluent of dichloromethane:petroleum ether=1:3 to obtain compound 3 with HPLC purity of 99.11% and yield of 75.89%; elemental analysis structure (C 48 h 30 N 6 O) Theoretical: C, 81.57; H, 4.28; N, 11.89; Found:...

Abstract

The invention discloses an organic compound containing a triazine structure, and belongs to the technical field of semiconductor materials. The structure of the compound provided by the invention is shown as a general formula (I); the compound provided by the invention has the characteristics of relatively high glass transition temperature and molecular thermal stability, good electron mobility, relatively low evaporation temperature, proper HOMO/LUMO energy level and the like. When the compound is used as a material of the organic electroluminescent device, the driving voltage, the current efficiency and the service life of the device are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor materials, in particular to an organic compound containing a triazine structure and its application in organic electroluminescent devices. Background technique [0002] Organic electroluminescent device (OLED: Organic Light Emission Diodes) technology can be used to manufacture new display products and also can be used to make new lighting products. It is expected to replace the existing liquid crystal display and fluorescent lighting, and has a wide application prospect. The OLED device has a sandwich-like structure, including electrode material film layers and organic functional materials sandwiched between different electrode film layers. Various functional materials are stacked together according to the application to form an OLED light-emitting device. OLED light-emitting devices are current devices. When a voltage is applied to the electrodes at both ends, and the positive and negative...
