8-HYDROXYQUINOLINE-BASED WHITE-LIGHT-EMITTING ORGANIC ELECTROLUMINESCENT MATERIAL

摘要

A white light emitting organic electroluminescent material based on 8-hydroxyquinoline and the preparation method thereof, and an electroluminescent device containing such material. The material may be the compound of formula (IX), which uses CDCD group, 5-substituted 8-hydroxyquinoline zinc group and carbazolyl group as red, green and blue light-emitting groups, and has spectral bandwidth of 182.4 nm covering basically the visible light emitting region and color coordinate (0.3177, 0 3946) within the white light region. The material can emit white light and can be used in white light OLED as single light-emitting layer.
