COLOR CONVERSION FILM COMPRISING CONJUGATED HIGH-MOLECULAR-WEIGHT COPOLYMER, AND MULTI-COLOR-EMITTING ORGANIC EL DEVICE USING THE SAME

摘要

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.
