<p>Disclosed is a polymer compound which, when used in a light-emitting device, imparts an excellent luminance life to the light-emitting device. Specifically disclosed is a polymer compound comprising a structural unit represented by formula (1). In formula (1), R1A, R1B, R2A and R2B represent an unsubstituted alkyl group; R3 and R4 represent an unsubstituted or substituted alkyl group, an unsubstituted or substituted alkoxy group, an unsubstituted or substituted aryl group, an unsubstituted or substituted aryloxy group, an unsubstituted or substituted heterocyclic group, an unsubstituted or substituted silyl group, a halogen atom, an alkoxycarbonyl group, a carbonyl group or a cyano group; R5 and R6 represent an unsubstituted or substituted alkyl group, an unsubstituted or substituted alkoxy group or an unsubstituted or substituted aryl group; and a, b, c and d represent each an integer of 0-3, provided that when there are multiple R3's, R4's, R5's and R6's, these R3's, R4's, R5's and R6's may be either the same or different.</p> |
