Abstract
A novel electroluminescent polymer is represented by the general formula (I).
A is (a-1) or the like, and B or B′ is either the following (b-1) or (b-2). A film of the polymer represented by the general formula (I) can be formed by electrolytic polymerization, and further emits light in a different color by an electric field when a substituent thereof is changed. Therefore, a light-emitting device that is capable of multicolor displaying can be easily obtained.
