Embodiment 1
[0303] The anode is prepared by the following process: the thickness is The ITO substrate (manufactured by Corning) was cut into a size of 40mm × 40mm × 0.7mm, and a photolithography process was used to prepare it into an experimental substrate with patterns of cathodes, anodes and insulating layers, using ultraviolet ozone and O 2 :N 2 A plasma surface treatment was performed to increase the work function of the anode (experimental substrate) and to remove scum.
[0304] Vacuum evaporation of F4-TCNQ on the experimental substrate (anode) to form a thickness of The hole injection layer (HIL), and NPB was evaporated on the hole injection layer to form a thickness of the first hole transport layer.
[0305] PAPB was vacuum evaporated on the first hole transport layer to form a thickness of the second hole transport layer.
[0306] On the second hole transport layer, compound 1:GH-N:Ir(ppy) 3 Co-evaporation was performed at a ratio of 60:40:10% (co-evaporation rate rati...
Embodiment 2~ Embodiment 89
[0310] Organic electroluminescent devices were fabricated by the same method as in Example 1, except that the compounds shown in Table 11 were used instead of Compound 1 when forming the light-emitting layer.
