Title:
ORGANIC LIGHT EMITTING DEVICE MATERIAL AND ORGANIC LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO2004046274
Kind Code:
A3
Abstract:
The present invention provides phosphorescent materials and polymer phosphorescent materials that generate lights of various colors including blue, green, yellow, orange and red, which are useful for high performance multicolor organic light-emitting EL devices, and also provides an organic light emitting device material containing a gold complex represented by formulae such as (2) and (6) below (symbols in the formulae are as described in the specification) in which gold is bonded to at least one atom selected from carbon, oxygen and sulfur, and organic light-emitting EL device including the material in its light-emitting layer.
