[0464] Polymer preparation

[0465] Preparation of compound 1

[0466]

[0467] Under nitrogen atmosphere, intermediate A (2.4g, 4mmol), intermediate B (1.4g, 4mmol), tris(dibenzylideneacetone)dipalladium(0) (183mg, 0.05eq), 1,1' - Bis(diphenylphosphino)ferrocene (55.4 mg, 0.1 equiv) and sodium tert-butoxide (1.2 g, 12 mmol) were added to toluene (80 ml) and refluxed at 80° C. for 24 hours. After the reaction was completed, methanol was poured into the reaction mixture to perform filtration, thereby obtaining a polymer.

[0468] The obtained polymer was dissolved again in toluene (20ml), and bromobenzene (0.16g, 1mmol), tris(dibenzylideneacetone)dipalladium(0) (46mg, 0.05eq), 1,1 '-bis(diphenylphosphino)ferrocene (14mg, 0.1 equivalent) and sodium tert-butoxide (0.4g, 4mmol), and refluxed at 80°C for 4 hours, to which N,N-diphenylamine (0.17 g, 1 mmol), and reflux again at 80°C for 4 hours. After the reaction was completed, methanol was poured thereinto for filtratio...

example 1

[0521] As the anode, a 15Ω / cm 2 The ITO glass substrate was cut into a size of 50 mm×50 mm×0.7 mm, ultrasonicated for 5 minutes each using isopropanol and pure water, and cleaned by ultraviolet irradiation and ozone exposure for 30 minutes. PEDOT-PSS was coated on the substrate and heat-treated at 150 °C for 30 minutes to form a The thickness of the hole injection layer. Inkjet deposition of ink 1 on the hole injection layer to form a thickness of the hole transport layer, which was dried at 230 °C for 30 min. By using ink dissolved in methyl benzoate, compound A as a fluorescent host and compound B as a fluorescent dopant were inkjet deposited on the hole transport layer at a weight ratio of 95:5 to form a thickness of the emissive layer. Compound ET1 is deposited on the emissive layer to form a The thickness of the electron transport layer, LiF is deposited on the electron transport layer to form a The thickness of the electron injection layer, Al is deposited o...
