Embodiment 1

[0072] Example 1: Synthesis of Compound 2

[0073]

[0074] (1) In a 250ml three-necked flask, under the protection of nitrogen, add 0.01mol 1-bromo-2,4-diiodobenzene, 0.008mol raw material A-1, 100mL ethylene glycol dimethyl ether, stir and mix, then add 5 ×10 -5 mol PdCl 2 (PPh 3 ) 2 , 20mL of 2M potassium carbonate aqueous solution, heated to 60°C, refluxed for 10 hours, sampling points showed that there was no A-1 remaining, the reaction was complete; naturally cooled to room temperature, filtered, the filtrate was rotary evaporated to no fraction, and passed through a neutral silica gel column, The intermediate product M-1 was obtained with an HPLC purity of 99.66% and a yield of 76.8%. HRMS (EI): The molecular weight of the material is 447.8960, and the measured molecular weight is 447.8929;

[0075] (2) In a 250ml three-necked flask, under the protection of nitrogen, add 0.01mol of the intermediate product M-1 obtained in step (1) and 0.01mol of raw material B-1, 150ml of x...

Abstract

The invention discloses a compound taking a carbazole ring as a core, a preparation method and application thereof, wherein the structure of the compound is represented by a general formula (1). The compound provided by the invention has high glass transition temperature and molecular thermal stability, proper HOMO and LUMO energy levels and high mobility, and can effectively improve the photoelectric property of an OLED device and prolong the service life of the OLED device by optimizing the structure of the device.

Description

Technical field [0001] The present invention relates to the technical field of organic electroluminescence materials, in particular to a compound containing a carbazolo ring in its structure, and a preparation method and application thereof. Background technique [0002] Organic Light Emission Diodes (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products as well as new lighting products. It is expected to replace the existing liquid crystal display and fluorescent lighting, and has a broad application prospect. [0003] The OLED light-emitting device is like a sandwich structure, including electrode material film layers and organic functional materials sandwiched between different electrode film layers. Various functional materials are superimposed on each other according to the purpose to form an OLED light-emitting device. As a current device, when a voltage is applied to the electrodes at both ends of the OLED light-emitting devic...
