[0123]Implementation
[0124]The OLED includes a first electrode and a second electrode, and an organic material layer between the electrodes. The organic material can be divided into multiple regions. For example, the organic material layer may include a hole transport area, a light emitting layer, and an electron transport area.
[0125]In a specific embodiment, a substrate may be used below the first electrode or above the second electrode. The substrates are all glass or polymer materials with excellent mechanical strength, thermal stability, water resistance, and transparency. In addition, thin film transistors (TFT) may also be provided on a substrate used as a display.
[0126]The first electrode may be formed by sputtering or depositing a material used as the first electrode on the substrate. When the first electrode is used as an anode, transparent conductive materials such as indium tin oxide (ITO), indium zinc oxide (IZO), tin dioxide (SnO2), zinc oxide (ZnO), and any combination ...
Example Embodiment
[0172]Example 1:
[0173]Preparation of organic electroluminescent device IVD-1, the specific preparation process is as follows:
[0174]The glass plate coated with the transparent conductive layer of ITO is ultrasonically treated in a commercial cleaning agent, rinsed in deionized water, degreasing ultrasonically in a mixed solvent of acetone and ethanol, and baked in a clean environment until the water is completely removed. Light and ozone cleaning, and bombard the surface with low-energy cation beams;
[0175]Put the above-mentioned glass substrate with anode in a vacuum chamber and evacuate to-5Pa, 10nm HT-4:HI-3 (97 / 3, w / w) mixture was vacuum thermally evaporated on the above-mentioned anode layer film as the hole injection layer, 60nm compound C1 of the present invention was used as the hole transport Floor;
[0176]Vacuum evaporate HT-14 on the hole transport layer as the electron blocking layer of the device, the evaporation rate is 0.1nm / s, and the total evaporation film thickness is ...
Example Embodiment
[0179]Example 2-7:
[0180]The organic electroluminescent devices IVD-2 to IVD-7 were prepared by the same method as IVD-1, replacing C1 in the hole transport layer with the corresponding material as described in the hole transport layer in Table 1.
