Title:
COLOR CONVERSION FILM COMPRISING CONJUGATED HIGH-MOLECULAR-WEIGHT COPOLYMER, AND MULTI-COLOR-EMITTING ORGANIC EL DEVICE USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/143276
Kind Code:
A1
Abstract:
Disclosed is a color conversion film which can keep the converted-light intensity at a satisfactory level for a long period without the need of increasing the thickness thereof. The color conversion film is characterized by comprising a conjugated high-molecular-weight copolymer having such a structure that a repeating unit having a fluorene group and an arylenevinylene repeating unit are contained in an alternating sequence and a phenylene group is inserted to both termini of the fluorene group as a spacer (i.e., a structure represented by formula (1)). Also disclosed is a multi-color-emitting organic EL device produced by using the color conversion film.
