[0122] Preparation method of organic light emitting diode device:
[0123] (1) First, the ITO substrate was cleaned in the following order: 5% KOH solution ultrasonic for 15 min, pure water ultrasonic for 15 min, isopropanol ultrasonic for 15 min, oven drying for 1 h; then the substrate was transferred to UV-OZONE equipment for surface treatment for 15 min, treated Transfer to the glove box immediately after finishing.
[0124] (2) A layer of hole injection layer material, namely PEDOT:PSS film, was spin-coated on a clean ITO substrate, and then baked at 230 °C for 15 min. A layer of HTL layer thin film, namely VNPB, was spin-coated on the hole injection layer, and the thin film was baked at 200° C. for 30 min after spin-coating.
[0125] (3) A layer of HTL layer thin film, namely VNPB, was spin-coated on the hole injection layer, and the thin film was baked at 200° C. for 30 min after spin-coating.
[0126] (4) Dissolve the dendrimer compound with solvent o-xylene and prepa...
