Embodiment 1

[0114] The synthesis of embodiment 1 compound 1:

[0115] synthetic route:

[0116]

[0117] In a 250ml four-neck flask, under nitrogen atmosphere, add 11.8g 1,4-dibromobenzene (0.05mol) and 1.33g Mg powder (0.055mol), 60ml tetrahydrofuran, heat and reflux for 4 hours, no Mg powder remains, The reaction is complete, and the format reagent is generated;

[0118] 9-Fluorenone (9.01g, 0.05mol) was dissolved in 50ml tetrahydrofuran, the above-mentioned Grignard reagent was added dropwise, heated to 60°C for 24 hours, a large amount of white precipitate was formed, and finally saturated NHCl was added 4 solution until the precipitation disappears, the Grignard salt is converted into a tertiary alcohol; after the reaction is completed, extract with 100ml ether, the extract is dried with anhydrous sodium sulfate, the solution is rotary evaporated to remove the solvent to no fraction, and the mixed solvent of petroleum ether and dichloromethane ( Volume ratio 3:2) is the neutral ...

Abstract

The invention discloses a fluorene-containing compound and an application thereof. The compound has the structure shown in the general formula (1). The compound has higher glass transition temperatureand molecular heat stability, proper HOMO and LUMO energy levels and higher Eg, the photoelectric property of an OLED (organic light emitting diode) device can be effectively improved and the servicelife of the OLED device can be effectively prolonged through structure optimization of the device.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a compound material containing fluorene as a central skeleton and its application in the field of OLEDs. Background technique [0002] Organic electroluminescent (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products and also can be used to make new lighting products, which is expected to replace the existing liquid crystal display and fluorescent lighting, and has a wide 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 application 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 device, a...
