Embodiment 1

[0085] Example 1: Synthesis of Compound 631

[0086]

[0087] Referring to the general synthetic route, the K 2 PtCl 4 (1.1 mmol), Ligand 1 (1.2 mmol), CHCl 3 (75 mL) and AcOH (50 mL) were added to a two-necked round-bottomed flask, then heated under reflux for 120 hours, stopped heating, cooled to room temperature, and removed the solvent. The resulting solid was extracted several times with dichloromethane, then dried and concentrated, and the crude product was purified with a short column of silica gel. The solvent was removed under reduced pressure, and the solid obtained by concentration was recrystallized with methanol and dichloromethane to obtain the final target product. The yield of the final product was 34%. Mass spectrum m / z, theoretical value 1010.35; observed value M+H: 1011.38.

Embodiment 2

[0088] Example 2: Synthesis of Compound 632

[0089]

[0090] Referring to the general synthetic route, the yield of the final product was 41%. Mass spectrum m / z, theoretical value 1016.39; observed value M+H: 1017.51.

Embodiment 3

[0091] Example 3: Synthesis of Compound 633

[0092]

[0093] Referring to the general synthetic route, the yield of the final product was 36%. Mass spectrum m / z, theoretical value 960.33; observed value M+H: 961.35.

Abstract

The invention provides an organometallic complex. The structure of the organometallic complex is shown as a formula I. An organic optoelectronic device comprising the organometallic complex has good luminous efficiency, reduced driving voltage and prolonged service life.

Description

technical field [0001] The invention relates to an organometallic complex, in particular to an organometallic complex, a preparation, an organic optoelectronic device and a display or lighting device, and belongs to the field of organic optoelectronics. Background technique [0002] Organic optoelectronic devices (especially organic electroluminescent diodes (OLEDs)) have the advantages of self-luminescence, wide viewing angle, low energy consumption, high efficiency, thinness, rich colors, fast response speed, wide application temperature range, low driving voltage, flexible The unique advantages of curved and transparent display panels and environmental friendliness can be applied to flat panel displays and next-generation lighting, and can also be used as a backlight for LCDs. [0003] Since its invention in the late 1980s, OLED has been applied in industry. OLED emits light in two ways: fluorescence emission and phosphorescence emission. According to theoretical speculat...
