RED COLOR PHOSPHORESCENT MATERIAL CAPABLE OF IMPROVING CHROMATIC PURITY AND LUMINOUS EFFICIENCY, AND AN ORGANIC ELECTROLUMINESCENT DEVICE USING THEREOF

摘要

PURPOSE: A red color phosphorescent material for an organic electroluminescent device is provided to secure high purity and high brightness of an image of the electroluminescent device.;CONSTITUTION: A red color phosphorescent material contains a host material capable of transferring electrons or holes, and a dopant material marked as the chemical formula 1. In the chemical formula 1, R1 to R4 refer to an alkyl group with hydrogen and C1~6, or an alkoxy group with C1~6. R5 to R7 refer to the alkyl group with the hydrogen and the C1~6, or a halogen atom, respectively. X and Y refer to an un-substituted alkyl group with the hydrogen and the C1~6, or a fluorinated alkyl group with the C1~6.;COPYRIGHT KIPO 2010
