Although organic light-emitting device (OLED) has been commercialized since 1997,blue light-emitting material is still a challenge for full color display. It is crucial to develop blue emitting material with high efficiency and color purity. The thermal stability and its color purity of blue electrophosphorescent materials are still far from commercialization,but a lot of achievements on excellent blue electrofluorescent materials have been made. Anthracene derivatives and spirobifluroene compounds show high performance in thermal stability and color purity,while nitrogen-containing compounds are competitive in efficiency because of their special electronic structure. Based on its structure,the blue electrofluorescent materials can be classified into aromatic hydrocarbons,nitrogen-containing compounds,and other organic compounds containing other hetero-atoms. The developments of blue electrofluorescent materials are reviewed at present,and the prospect on blue electrofluorescent materials is also discussed.
