Dark blue organic light-emitting material with high exciton utilization rate and preparation and application thereof

The invention belongs to the technical field of organic photoelectric materials, and discloses a dark blue organic light-emitting material with a high exciton utilization rate as well as preparation and application thereof. The structure of the dark blue organic light-emitting material is shown as a formula I in the specification. The invention also discloses a preparation method of the dark blueorganic light-emitting material. The material provided by the invention is a dark blue luminescent material, can form hybrid local charge transfer state (HLCT) luminescence, realizes crossing of high-energy triplet state heat excitons to a singlet state reverse system, and improves the exciton utilization rate. Meanwhile, the dark blue organic light-emitting material is high in fluorescence quantum yield and high in carrier mobility. The material provided by the invention has good performance in organic light-emitting devices. The dark blue organic light-emitting material is used for preparingan organic light-emitting device.

SECONDARY HOLE TRANSPORTING LAYER WITH DIARYLAMINO-PHENYL-CARBAZOLE COMPOUNDS

Novel diarylamino phenyl carbazole compounds are provided. By appropriately selecting the nature of the diarylamino substituent and the substitution on the carbazole nitrogen, compounds with appropriate HOMO and LUMO energies can be obtained for use as materials in a secondary hole transport layer.
