Potassium is added in dry dimethyl sulfoxide (DMSO), under the protection of nitrogen, 90 DEG C is heated to while stirring, reacts 12h, and cooling is stood afterwards
To room temperature, extracted with water and dichloromethane, then dried with anhydrous magnesium sulfate, filtering, and remove organic solvent, obtain end-product thick
Product;And post purifying is crossed, obtain the borate of carbazole;
The borate of carbazole and R-X (X is halogen) and tetrakis triphenylphosphine palladium are added to toluene, ethanol and 2M carbon by step b '
In the mixed solution of sour aqueous solutions of potassium, under the protection of nitrogen, side stirring change is heated to 90 DEG C, reacts 12h, stands be cooled to afterwards
Room temperature, is extracted with water and dichloromethane, then is dried with anhydrous magnesium sulfate, filtering, and removes organic solvent, obtains product crude product;
And post purifying is crossed, obtain the carbazole monomers of R substitutions;
The carbazole monomers that step c replaces above-mentioned R are added to 1,2- dichloros with potassium carbonate, potassium hydroxide and TBAB
In ethane, 5h is reacted under the conditions of 50 DEG C, stand be cooled to room temperature afterwards, extracted with water and dichloromethane, then use anhydrous magnesium sulfate
Dry, filtering, and remove organic solvent, obtain product crude product;And post purifying is crossed, obtain the chloroethyl carbazole monomers of R substitutions;
Chloroethyl carbazole monomers that step d replaces R obtained above and potassium hydroxide, hydroquinones be added to isopropanol and
In the mixed solution of toluene, 3h is reacted under the conditions of 85 DEG C, stand be cooled to room temperature afterwards, solvent is spin-dried for, with water and dichloromethane
Extraction, then dried with anhydrous magnesium sulfate, filtering, and organic solvent is removed, obtain product crude product;And post purifying is crossed, obtain final
Monomer.
4. a kind of application of new bipolar polymer host material as claimed in claim 1, it is characterised in that the material and phosphorus
It is applied in organic electroluminescence device as luminescent layer after the doping of light guest emitting material.Knot in organic electro phosphorescent device
Structure is:Transparent anode/hole transmission layer/polymer host material and phosphorescent guest luminescent material/electron transfer layer/metal are cloudy
Pole, the compound of the material of main part of luminescent layer as described in right 1, guest materials is metal complex phosphor material.
