Abstract:

The 1,3,4-oxadiazole ring is known as a group which has high electron affinity and hole blocking effect. The compounds containing such a group are a kind of electro-luminescent material which has good electron transporting capability. The blue-light-emitting organic electro-luminescent material with 1,3,4-oxadiazole ring is recently a research focus in materials science. The research status of molecular structures, properties and related device performance of small molecular and macromolecular blue-light-emitting organic electro-luminescent materials with 1,3,4-oxadiazole ring is reviewed, and the prospect of molecular design to improve the properties of these materials is also presented.
