CONJUGATED HIGH-MOLECULAR-WEIGHT COPOLYMER, COLOR CONVERSION FILM USING SAME, AND MULTICOLOR LIGHT-EMITTING ORGANIC EL DEVICE

摘要

Disclosed is a green light-emitting color conversion film which can be produced by a low-cost wet process and is capable of maintaining a sufficient converted light intensity for a long time without having an increased thickness.  The color conversion film contains a conjugated high-molecular-weight compound represented by general formula (1).  Also disclosed is a multicolor light-emitting organic EL device which comprises: a pair of electrodes, at least one of which is a transparent electrode; an organic EL layer interposed between the pair of electrodes; and a color conversion film containing a conjugated high-molecular-weight compound.
