Title:
COMPOSITION CONTAINING POLYMER COMPOUND AND LIGHT-EMITTING ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/008493
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a composition using a polymer compound and useful for producing a blue phosphorescent light-emitting element having excellent light-emitting efficiency. The present invention provides a composition comprising: a polymer compound which substantially comprises structural units selected from a structural unit represented by formula (1)-1, a structural unit represented by formula (1)-2, a structural unit represented by formula (2)-1, a structural unit represented by formula (2)-2, and a structural unit derived from a phosphorescent light-emitting compound having an emission spectral peak less than 480 nm and which contains at least both of the structural unit represented by formula (1)-1 and the structural unit represented by formula (1)-2; and a phosphorescent light-emitting compound having an emission spectral peak less than 480 nm.
