Organic luminescent material and preparation method and application thereof

The invention provides an organic light-emitting material as well as a preparation method and application thereof. The organic light-emitting material has a structure as shown in a formula I, the organic light-emitting material provided by the invention is a novel benzimidazole derivative, can be used as an efficient electron transport material, and not only has excellent carrier injection and transport performance, but also has good stability; the organic electroluminescent material is suitable for preparing an electron transport material of an OLED device, can reduce the turn-on voltage of the OLED device, improves the luminous efficiency, and prolongs the service life.

4H-IMIDAZO[1,2-A]IMIDAZOLES FOR ELECTRONIC APPLICATIONS

The present invention relates to compounds of formula (I), a process for their production and their use in electronic devices, especially electroluminescent devices. When used as electron transport and/or host material for phosphorescent emitters in electroluminescent devices, the compounds of formula I may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.
