RED PHOSPHORESCENCE COMPOUND AND ORGANIC ELECTROLUMINESCENCE DEVICE USING THE SAME

摘要

A red phosphorus compound is provided to increase the color purity and to ensure high luminescence efficiency and long lifetime by synthesizing the chemical formula 1 used as a dopant of a light-emitting layer. A red phosphorus compound is represented by the chemical formula 1. In the chemical formula 1, the formula (a) is the formula (b); R1 is selected from a group consisting of C1 - C6 alkyl group and aryl; R2 and R3 are independently selected from a hydrogen, C1 - C6 alkyl group, and C1 - C4 alkoxy group; at least one of R2 and R3 is C1 - C6 alkyl group or C1 - C4 alkoxy group.
