Embodiment 1
[0137] Embodiment 1: red organic electroluminescent device
[0138] The anode was prepared by the following process: the thickness was The ITO / Ag / 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 was used for surface treatment to increase the work function of the anode (experimental substrate) and to remove scum.
[0139] Vacuum evaporation on the experimental substrate (anode) The HAT-CN is used as the hole injection layer (HIL), and then evaporated on the hole injection layer NPB, forming the first hole transport layer (HTL).
[0140] Compound 13 is vacuum evaporated on the first hole transport layer to form the second hole transport layer.
[0141] On the second hole-transporting layer, combine RH-1 with Ir(piq) 2 (acac) is co-evaporated at a 95%:5% e...
Embodiment 2~55
[0145] An organic electroluminescent device was fabricated using the same method as in Example 1, except that compounds shown in Table 8 below were used instead of Compound 13 when forming the second hole transport layer.
