[0057] Preparation Example 1: Synthesis of Compound 6

[0058]

[0059] In a 250mL three-neck flask, nitrogen gas was introduced, 0.02mol of raw material I, 150ml of DMF, 0.022mol of raw material II, 0.0002mol of palladium acetate were added, stirred, and then 3mL of 0.01mol / mLK was added. 3 PO 4 Aqueous solution, heated to reflux at 150°C for 12 hours, sampled and plated, the reaction was complete. Cool naturally, add 100mL of water, filter the mixture and take the filter cake to dry in a vacuum oven, and the resulting residue is purified through a silica gel column to obtain raw material A-1; elemental analysis structure (molecular formula C 24 h 15 BrIN): theoretical C, 54.99; H, 2.88; Br, 15.24; I, 24.21; N, 2.67; found: C, 54.98; H, 2.87; Br, 15.25; ESI-MS(m / z)(M + ): The theoretical value is 524.20, and the measured value is 524.28.

Abstract

The invention relates to an organic compound containing triarylamine and carbazole, and an application thereof, and belongs to the technical field of semiconductors. The structure of the compound is represented by general formula (I) shown in the description. The compound provided by the invention has a strong hole transport ability, so the hole injection and transport performances are improved atan appropriate HOMO level; and the organic compound also has an electron blocking at an appropriate LUMO level, so the recombination efficiency of excitons in a luminescent layer is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor materials, in particular to an organic compound containing triarylamine and carbazole and its application in organic electroluminescent devices. Background technique [0002] At present, OLED display technology has been applied in smart phones, tablet computers and other fields, and will further expand to large-size applications such as TVs. However, compared with actual product application requirements, the luminous efficiency and service life of OLED devices Further improvement is required. The current research on improving the performance of OLED light-emitting devices includes: reducing the driving voltage of the device, improving the luminous efficiency of the device, and improving the service life of the device. In order to realize the continuous improvement of the performance of OLED devices, not only the innovation of OLED device structure and manufacturing process is required, but ...
