Embodiment 1

[0083] Example 1: Synthesis of intermediate A1:

[0084] synthetic route:

[0085]

[0086] In a 250ml four-neck flask, add 11.8g 1,4-dibromobenzene (0.05mol), 1.2gMg powder (0.05mol), 60ml tetrahydrofuran, and reflux for 4 hours under a nitrogen atmosphere. The reaction is complete. Reagent

[0087] 9.0g of 9-fluorenone (0.05mol) was dissolved in 50mL of tetrahydrofuran, and the above reagent was added dropwise, and reacted at 60℃ for 24 hours, a large amount of white salt was formed, and saturated NHCl was added. 4 Solution until the precipitation disappears, the formal salt is converted into tertiary alcohol; after the reaction is completed, it is extracted with 100ml ether, the extract is dried with anhydrous sodium sulfate, the solution is evaporated to remove the solvent until there is no distillate, and the tertiary alcohol crude product is obtained. The mixed solvent of petroleum ether and dichloromethane (volume ratio 3:2) was used as the eluent to be purified by neutral si...

Embodiment 2

[0089] Example 2: Synthesis of Intermediate A2:

[0090] synthetic route:

[0091]

[0092] The intermediate A2 was prepared according to the synthesis method of the intermediate A1 in Example 1, except that 1,1'-biphenyl was used instead of the compound bromobenzene;

[0093] Use DEI-MS to identify the compound, molecular formula C 31 H 21 Br, detection value [M+1] + =473.31, the calculated value is 472.08.

Embodiment 3

[0094] Example 3: Synthesis of Intermediate A3:

[0095] synthetic route:

[0096]

[0097] Intermediate A3 was prepared according to the synthesis method of intermediate A1 in Example 1, except that benzene was used instead of bromobenzene in the third step of the reaction;

[0098] Use DEI-MS to identify the compound, molecular formula C 25 H 17 Br, detection value [M+1] + =397.21, calculated value 396.05.

Abstract

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

Description

Technical field [0001] The present invention relates to the field of semiconductor technology, in particular to a compound material containing fluorene as a central skeleton and its application in the field of OLEDs. 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 device, and the positive and n...
