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.
