Embodiment 1

[0045]Embodiment 1: the synthesis of target compound

[0046]

[0047] Under nitrogen atmosphere, add 0.06mol raw material B in the three-neck flask of 500ml, add mixed solvent (300ml toluene, 90ml H 2 O) it is dissolved, and nitrogen gas is stirred for 1 hour, then slowly add 0.05mol raw material A, 0.1mol K 2 CO 3 , 0.005mol Pd(PPh 3 ) 4 , heated to 90° C., reacted for 8 hours, and observed the reaction by thin layer chromatography (TLC) until the reaction was complete. After naturally cooling to room temperature, water was added to the reaction system for extraction, liquid separation, and the organic phase was rotary evaporated under reduced pressure until there was no distillate. The resulting material was purified by silica gel column to afford intermediate N.

[0048] Under a nitrogen atmosphere, add 0.06mol intermediate N to a 500ml three-necked flask, add a mixed solvent (300ml toluene, 90ml H 2 O) dissolve it, and stir for 1 hour with nitrogen gas, then slow...

Abstract

The invention discloses a triarylamine organic compound containing a pyrene structure and application of the triarylamine organic compound, and belongs to the technical field of semiconductors. The structure of the triarylamine organic compound containing the pyrene structure is shown as a general formula (I). The organic compound provided by the invention has a relatively high triplet state energy level, a relatively wide band gap and relatively high mobility, and a device adopting the organic compound provided by the invention can effectively improve the efficiency of an OLED (Organic Light Emitting Diode) device and prolong the service life of the OLED device through structural optimization.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a triarylamine organic compound containing a pyrene structure and an application thereof. 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. 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, and the positive and nega...
