Embodiment 1

[0153] Examples 1-19 selected the compound of the present invention as the electron transport material in the organic electroluminescent device, and Comparative Example 1 selected Alq3 as the electron transport material in the organic electroluminescent device.

[0154]The structure of the organic electroluminescence device is: ITO / HIL02 (100nm) / NPB (40nm) / EM1 (30nm) / ETL (20nm) / LiF (0.5nm) / Al (150nm).

[0155] The fabrication process of organic electroluminescent devices is as follows:

[0156] The glass substrate coated with the ITO transparent conductive layer (as the anode) is ultrasonically treated in a cleaning agent, then rinsed in deionized water, then ultrasonically degreased in acetone and ethanol mixed solvent, and then baked in a clean environment until Completely remove water, clean with ultraviolet light and ozone, and bombard the surface with low-energy cation beams to improve the properties of the surface and improve the binding ability with the hole injection l...
