Abstract
A polymer compound comprising a repeating unit represented by formula (1) and a repeating unit represented by formula (2), 1 —Ar6— (2) wherein, Ar1, Ar2 and Ar6 each independently represent an arylene group, a divalent heterocyclic compound group, etc.; Ar3 is an arylene group, arylene vinylene group, or a divalent heterocyclic compound group; Ar4 and Ar5 are each independently an aryl group or a monovalent heterocyclic compound group. The polymer compound has excellent characteristics of strong fluorescence and large charge transporting property.
