Abstract
The present invention provides an organic polymer light-emitting element material having a gold complex structure as a part of the side chain or crosslinking group as represented by formulae (5) and (8) and an organic polymer light-emitting element comprising layer(s) comprising the organic polymer light-emitting element material. The present invention provides a polymer-based phosphorescent material useful for a multicolor or white light-emitting organic EL device having high luminous efficiency and capable of large-area formation and mass production.
Claims3
An organic polymer light-emitting element material having a gold complex structure as a part of a side chain, which is obtained by polymerizing a composition containing a polymerizable gold complex represented by formula (5) or (9):
