【Abstract】 Oxadiazole units are known as electron deficient groups and poor hole acceptors. The compounds containing 1,3,4 oxadiazole units are a kind of electroluminescent material which has good electron transporting capability. In the paper, recent progresses of organic molecular and polymeric electroluminescent materials which contain 1,3,4 oxadiazole units are reviewed, and the prospect of molecular design of these materials are also given briefly.更多还原
