Embodiment 1
[0095] Embodiment 1: blue organic electroluminescent device
[0096] The anode was prepared by the following process: the thickness was The ITO substrate (manufactured by Corning) was cut into a size of 40mm×40mm×0.7mm, and it was prepared into an experimental substrate with cathode, anode and insulating layer patterns by photolithography process, and the surface was treated by ultraviolet ozone and O2:N2 plasma , to increase the work function of the anode (experimental substrate) and remove scum.
[0097] Vacuum evaporated m-MTDATA on the experimental substrate (anode) to form a thickness of The hole injection layer (HIL), and compound 1 is vacuum evaporated on the hole injection layer to form a thickness of The first hole transport layer (HT1).
[0098] Evaporate TCTA on the first hole transport layer to form a thickness of The second hole transport layer (HT2).
[0099] Using α,β-AND as the main body and doping 4,4'-(3,8-diphenylpyrene-1,6-diylbis(N,N-diphenylanili...
Embodiment 2-5
[0103] An organic electroluminescent device was fabricated by the same method as in Example 1 except that the compounds shown in Table 1 were each used when forming the first hole transport layer (HT1).
[0104] That is, Example 2 uses Compound 2 to make an organic electroluminescent device, Example 3 uses Compound 3 to make an organic electroluminescent device, Example 4 uses Compound 4 to make an organic electroluminescent device, and Example 5 uses Compound 5 to make an organic electroluminescent device. Light-emitting device, the device performance is shown in Table 1.
Embodiment 6
[0116] Embodiment 6: red organic electroluminescent device
[0117] The anode was prepared by the following process: the thickness was The ITO substrate (manufactured by Corning) was cut into a size of 40mm × 40mm × 0.7mm, and it was prepared into an experimental substrate with cathode, anode and insulating layer patterns by using a photolithography process, using ultraviolet ozone and O 2 :N 2 Plasma surface treatment was performed to increase the work function of the anode (experimental substrate) and to remove scum.
[0118] Vacuum vapor-deposit m-MTDATA on the experimental substrate (anode) to form a thickness of The hole injection layer (HIL), and NPB is evaporated on the hole injection layer to form a thickness of The first hole transport layer (HT1).
[0119] Compound 6 is vacuum evaporated on the first hole transport layer to form a thickness of The second hole transport layer (HT2).
