preparation example Construction
[0085] The present invention does not limit the preparation method of the light-emitting device, and conventional methods in the field are sufficient. In the present invention, methods such as thin film evaporation, electron beam evaporation or physical vapor deposition are preferably used to evaporate metals and conductive oxides on the substrate. and their alloys to form an anode, and then an organic layer and an evaporation cathode are formed thereon to obtain a light-emitting device.
[0086] The present invention also provides a light-emitting device comprising the above-mentioned light-emitting device.
[0087] Specifically, the above-mentioned light-emitting devices can be applied to organic light-emitting devices (OLEDs), organic solar cells (OSCs), electronic paper (e-paper), organic photoreceptors (OPCs), organic thin film transistors (OTFTs), and the like.
Embodiment 1
[0091] Raw material A is identical with raw material C in embodiment 1
[0092]
[0093] Under nitrogen protection, raw material A-37 (40.00 mmol) and raw material B-37 (40.00 mmol) were dissolved in toluene solution, sodium tert-butoxide (80.00 mmol), tris(dibenzylideneacetone)dipalladium ( 0.40 mmol), tri-tert-butylphosphine (2.00 mmol), stir evenly, heat up to 110 ° C, and reflux for 8 h; after the reaction, drop the temperature slightly, use celite for filtration, remove salt and catalyst, and cool the filtrate to room temperature Then, wash with water three times, keep the organic phase, and then extract the aqueous phase with ethyl acetate; after combining the organic phases, use anhydrous magnesium sulfate to dry, and use a rotary evaporator to remove the solvent, and dissolve in petroleum ether / ethanol, After recrystallization and filtration, the filter cake was rinsed with petroleum ether for several times, and dried in an oven at 60° C. for 5 h to obtain Intermedi...
