9,10-Bis[2-(p-substituted phenyl)pyrimidin-4-yl] Anthracene Compounds, Methods of Preparing the Same, Organic Electroluminescent Devices and Organic Electroluminescent Display Apparatus

摘要

The invention relates to organic electroluminescent materials and provides 9,10-bis[2-(p-substituted phenyl)pyrimidin-4-yl] anthracene compounds and methods of preparing the same, organic electroluminescent devices comprising the compounds, and organic electroluminescent display apparatus comprising the devices. The compounds of the invention are easy to be synthesized and can be used as blue-phosphorescent organic electroluminescent materials. Due to the inherent ability of the materials to block holes, there is no need to arrange a hole-blocking layer between a light-emitting layer and an electron transport layer, which simplifies the manufacturing process of full color display panels of organic electroluminescent display apparatus and reduces the manufacture cost and time. The organic electroluminescent devices made from the materials exhibit high luminous efficiency.
