preparation example 1

[0032] Synthesis of 2-(2,4-difluorophenyl)pyridine (2-(2,4-difluoro-phenyl)-pyridine) ligand (46dfppy for short):

[0033] The synthetic route is as follows:

[0034]

[0035] Get 2,4-difluorophenylboronic acid (2,4-difluorophenyl boronic acid) (1.0g, 6.3mmol) and palladium diacetate (Pd(acetate) 2) (0.036g, 0.16mmol) and triphenylphosphine ( triphenylphosphine) (0.168g, 0.641mmol) dispersed in 2M K 2 CO 3 Aqueous solution (12mL) and 1,2-dimethoxyethane (1,2-dimethoxyethane) (6mL) solvent, add dropwise 2-bromopyridine (2-bromopyridine) (0.6mL, 6.33mmol) in the above reaction flask solution, reflux for 24 hours. After the reaction was completed, let it stand to cool to room temperature, and drain the solvent in the reaction bottle to obtain a yellow-brown solid, which was dissolved in an appropriate amount of water (60mL), and extracted with dichloromethane (50mL×2). Take the organic layer and reuse Na 2 SO 4 In addition to water, use the filter plate to remove Na 2 S...

[0040] cyclometalated Pt(II)μ-chloro-bridge dimer[(46dfppy)Pt(μ-Cl) 2 Synthesis of Pt(46dfppy)]:

[0041] The synthetic route is as follows:

[0042]

[0043] Take potassium tetrachloroplatinate (II) (potassium tetrachloroplatinate (II)) (0.54g, 1.3mmol) and 2-(2,4-difluorophenyl)pyridine (2-(2,4-difluoro-phenyl)- pyridine) (0.52g, 2.73mmol) was dissolved in the mixed reagent of adding glycol ether / water=3:1 as a solvent, and after reflux reaction for 24 hours, after the reaction was completed, water (20mL) was added in the reaction flask, and A large amount of solids were precipitated, and the product was obtained by air suction and filtration. After repeated rinsing with water and n-hexane for many times, it was vacuum-dried to obtain a platinum metal two-body complex with a yield of 0.89g (1.07mmol, 82 %).

[0045] cyclometalated Pt(II)μ-chloro-bridge dimer[(ppy)Pt(μ-Cl) 2 Synthesis of Pt(ppy)]:

[0046] Synthetic route:

[0047]

[0048] Potassium tetrachloroplatinate (II) (1g, 2.41mmol) was dissolved in a mixed reagent of ethylene glycol ether / water=3:1 as a solvent, and phenylpyridyl (phenylpyridyl) (1.12g, 7.23mmol) was added dropwise ), after reflux reaction for 24 hours, after the reaction is completed, add water (20mL) in the reaction bottle, a large amount of solids will be precipitated, and the product will be obtained by air suction and filtration. After repeated washing with water and n-hexane for many times , vacuum-dried to obtain a platinum double-body complex with a yield of 1.57 g (2.05 mmol, 85%).

Abstract

An organic metal complex and the organic electroluminescent device containing said organic metal complex are disclosed.

Description

technical field [0001] The invention relates to an organic metal complex, in particular to an organic double metal complex used in an organic electroluminescent device, which has a metal-metal bond and can be used as a light-emitting layer of the organic electroluminescent device. Background technique [0002] An organic electroluminescent device, also known as an organic light-emitting diode (OLED), is a light-emitting diode (LED) that uses an organic layer as an active layer. Due to the advantages of low-voltage operation, high brightness, light weight, wide viewing angle, and high contrast value, organic electroluminescent devices have been gradually used in flat panel displays in recent years. [0003] In general, an OLED includes a counter electrode, and a light emitting layer between the electrodes. Luminescence is caused by the following phenomenon. When an electric field is applied to the two electrodes, the cathode emits electrons to the light-emitting layer, and ...
